everyone welcome back to another episode of ask GN as always if you have questions for next episode leave them in the comment section below or in the SDN channel on patreon of the in the discord so for this one we have a couple questions about under bolting and whether that can actually hurt your hardware and a couple of other good ones including talking about well we have a present for NZXT that will catch you later in the episode before that this video is brought to you by the new cable mod pro series cable mods new pro cables come with pre-installed closed combs for clean builds accompanied by a revamped color style and vibrance the cables are now using thicker wires and they've also added right-angled internal USB 3 extension and right angled SATA data cables by the pro series cable kits at the link below or customize that your cable set with the configurator also linked below prior to starting I want to show off two new things that we just added to the store one is a hoodie I think it's pronounced Raglan I'm not sure the type of hoodie where it has different colored sleeves so it's a two-tone and we have the GN I just gave everyone the middle finger I mean the GN logo on the chest and on the back side under the blue hoodie is the teardown or anniversary edition logo so really happy with how it came out it's a pretty snug fit and it's really like a lightweight material as opposed to the other hoodies we have that are more for winter weather so this is more like spring or I don't know mid 60s weather or something like that but super lightweight and a cool design bit different so we're pretty happy with it that's on the store already if you're interested and then we also added we previously sold these black flex fit hats and now we're trying out a blue and white striped two-tone hat also on the store at store rock gamers nexus net so starting out first of all I guess I'll point out the previous content we did something cool with the motherboard for that we were talking about previously in a CSB through the em-dash II board with no vrm cooling and got it up to about 150 degrees internal mosfet temperature you should check out that content if you haven't it's from the day before this video went up I think so first real question NatWest said or no twist whatever it is said can under vaulting the GPU hurt the card in any way particularly if during testing you undervolt too far and it gets unstable not really over or yeah applying voltage to a CP or something you can certainly damage stuff on a hardware that will by by giving it too much voltage you can see previous video for that but in terms of under bolting especially on a GPU you don't have a lot of control or voltage for GPS anyway and then for the level of control that you do have if you under bolt too far and it becomes unstable the panel which GPU you're using one of two things will really happen one is it ignores your request and it just applies the voltage it wants this is why with like everyone talking about I under bull today a gun I got way less power consumption okay great but also if you type in really as we found if you type in a really low number for the voltage and it looks like it's stable it's probably just actively adjusting upwards to accommodate as necessary you can certainly under bolt it and you can certainly reduce power consumption but there's kind of a limit to it so the one possibility is that it ignores you if it's not enough voltage and just adjusts on-the-fly the other possibility is that it's unstable and crashes or has a driver crash or software issues things like that and these things don't hurt the hardware none of these would hurt the hardware the only real thing you could potentially lose I guess is maybe if you have a bad enough crash that you like some kind of bsod you could potentially corrupt system files or the application that was running we had this happen recently with Raven Ridge when we had that video bsod issue that was related to gpu-z and 3dmark fighting over asus info file that was out of date or different between the two of them so in that case it wasn't an under voltage saying however if you had a similar under voltage while many instability issue that caused a blue screen of death of a high enough severity you could maybe corrupt something like 3dmark but it's not really that big of a deal windows of course I know there's always potential potential to do damage to Windows but I have not personally had any issues with window is becoming corrupt from under bolting or anything like that it's typically like a driver crash and you restart and you increase the voltage and it's fine so the answer is now especially on a hardware level the answer's no but on a softer level it's maybe you might I don't know he might mess up a file or something if it's active any crash but I'm talking about the hardware next question is a pimp theis guy says why did nvidia decide to go 20 X X instead of 11 X acts like a lot of people were saying thanks for the great content so I think this is in reference the last time when I put GTX 20/80 and scare quotes the reason we did that is because that's what everyone was calling it that week that was the flavor of the week and that's why I had scare quotes around it so that's not like the actual name necessarily that was just me saying this is what everyone's expecting to see when we're talking about taurine or ampere or whatever it's the easy way to say this is what we're talking about and signal it it could very well be an 1100 series card I'm I don't know if any of the rumors actually have stated that they confidently know the name of the next card so yeah the answer to your question is Nvidia didn't necessarily decide that everyone on the internet decided that so I don't know maybe one of the rumors said 20xx but it's not confirmed next question galio says is it possible to damage or degrade a GPU more than in a normal use case space clocks just by overclocking the memory to hide no or no over-voltage power limit would be under set kiss times like a Mayan system parent would be under 70 and good temperatures 55 to 60 degrees Celsius I'm asking this because for example I have an MSI 1063 gigabyte with Samsung memory I can overclock it with plus 1000 and it doesn't crash when mining called it but in benchmarking I can see artifacts so I keep my OC at plus 700 you know I could get some extra mega hashes I don't know enough really about precisely how mining transacts memory but let's just answer this the base question here and without the specificity of mining and the base question is is it possible to damage the degrade GPU just by overclocking memory - hi the thing that starts damaging components is temperature is runaway thermals things like that so I don't what is the detail card this is 1060 gddr5 has a spec of something like ninety degrees Celsius I've taught my head I don't I I I'm pretty it's plus or minus five degrees it's in that range so let's say 90 degrees 85 to 95 basically is if I remember correctly what the spec is for gddr5 so as long as you're under that you're not causing any any serious damage I guess depending on if you're doing any weird BIOS mods or anything like that from mining with playing around with voltages that could change the story a bit but if you're just kind of running at stock and doing an offset on the memory I don't suspect that you should have any long-term damage or degradation from increasing the frequency if there's not also a significantly higher temperature on the on the dies so depend on how good your cooling is what kind of cooler you have on the card which brand it is it should be okay now 700 is pretty damn high though a thousand is really high so I don't know first question is is it actually doing plus a thousand because that sound that's pretty serious do like check gpu-z and some other software maybe do like a memory bandwidth test and see if you can actually validate in numbers and in scores that it is in fact offset by plus 1000 and if it is then great but that does sound awfully high as far as crashing at 1000 with gaming or benchmarking but not with mining this is just coming down to a matter of what type of software you're using so I can't speak to mine specifically but I can speak to some other things so let's talk about fur mark and fire strike because I know those with fur mark you can set whatever frequency you want but fur mark is ultimately a power virus test and I don't know maybe mining might be Haven I'm really not sure but fur mark is a power virus test so it puts a ton of load on the VRMs and the clocks will not actually be all that close or anywhere close actually to what they are in reality when you're gaming so you might see 1,200 to 1,400 megahertz clocks and fur mark with a Pascal card and then a game you might see 1800 but thermally you'll be in worst case with fur mark because it's burning the hell out of the VRMs and you'll be in similar or worse case with the GPU temperature so this is a matter of what type of instruction you're processing on the GPU and where it's being processed which specific piece of the GPU is being used to do the calculation I know that at some point with mining there is a switch and what specific hardware components they were using to do the calculations but I honestly don't know enough about it so perhaps someone in the comments can address that more specifically and educate all of us on what specifically mining does these days or what it loads on GPUs but with regard to instruction types just to give you an example from the CPU world one example would be prime95 with AVX instructions written on AVX so you go 26 point six versus twenty nine point two or twenty-eight point five for AVX and if you run the AVX person on EDX with largely the same settings you'll see way higher temperatures with AVX workloads blender is another application that uses AVX workloads and part of this is because the instruction types different and so on an Intel CPU for example you can burn to a BX threads versus one non AVX and so that will increase your sort of the the density of power in a particular spot of the die and therefore increase the core temperature of whatever core is being used to do the load so the roundabout thing I'm getting at here is although I can't answer your specific question about mining what I can say is that the instruction type matters and it's very common for some applications to be stable with an overclock but not others and with GPUs we see this with for example when we tested for honor and all of our GPU reviews we could hold a much higher overclock with other games but not in for honor and that was an instance of an applique dictating the stability it doesn't mean that your overclock is necessarily unstable overall but certainly of that game or in your case the benchmark you're talking about is part of your daily routine that you can't really qualify to us stable so you step it down and adjust accordingly because if it's a daily type application and you want to be able to actually be stable for it so the the long story short of this is it possible to down to degrade or damage the memory basically is what you're asking by running the overclock to high you can always damage stuff with too high of an overclock however the thing to keep an eye on is your thermals so if the memory is cooled sufficiently you've already eliminated most of the concern and beyond that just don't mess around with mods that you don't know what they do I guess so yeah hopefully someone else can post account though about the mind stuff because I'm curious as well as to how or what specifically on a card mining engages with these days I know it does stuff with memory I don't know what it does on the core though next question is from Andrews Ravens who says I took my reference r9 290x to a computer shop for changing the fan oh and thermal pads and thermal paste a day later they called me telling me that the heatsink is damaged and needs replacing I asked what was wrong with it and they said that it had run at high temperatures and has changed color okay haha so first of all a shop saying hey there's something wrong with your car can you come back and pick it up and you go back and and you brought in like a silver car and then they show you a blue one I don't I don't know that this is I don't know that this change of colors from your use it sounds like something may have happened in the repair process but I don't know so I asked what's wrong with it they said that I ran high temperatures okay I'm not sure if I should ask them to get a new heatsink because does not make sense that it's unusable just because the color has changed and that heat sinks get damaged from running at high temperatures maybe the liquid or the gas and the heat pipes is permeated through although that would not make sense because why would there be gas or liquid with a temperature range that lets it permeate at a temperature where graphics cards would still work this is an excellent point my question is that could a heat sink get damaged from a graphics card at 100 degrees Celsius or even 120 in an extreme case scenario at what temperature does the gas to liquid I'm gonna keep I permeate i I don't have a hard number for that what I can tell you is that your line of thought here it's correct if you're running at 100 degrees or let's say in your worst case 120 degrees on like the vrm or something the electrical components will get damaged first the rest of its copper I don't know what exact card you have but I'm assuming like most cards it's aluminum and copper and aluminum and copper don't melt or change color at even 100 degrees Celsius if they do it's so exceptionally minor that's completely irrelevant but definitely not any kind of like the only kind of damage I can think of so you've got like it what does a heat sink ultimately heat sink is metal aluminum copper and solder to hold the two together a heat sink has some liquid in the heat pipes but they are effectively a vacuum and and there's no reason that that should really I don't know I mean if it gets damaged because they if you if you dam really heats a heat pipe because you puncture it that's one story but if you're just running it on the card then no it's it's fine other than that fans and the fans are the first thing typically to go to the rest is metal and metal is pretty resilient does a hundred degrees is not a lot for copper to take so to answer your question I do not I can't think of a good common normal use reason that a heat sink would get damaged from even running with VRMs at 120 degrees because what will happen is maybe your VRMs are running pretty hot maybe your capacitor is nearby are rated for 105 C let's say it's a really cheap card five thousand hours maybe ten thousand hours so you have like five K caps 105 C and that's kind of a worst-case like cards running the first point of failure is gonna be a capacitor or a MOSFET or a power component and not the metal that's contacting those things so I don't know I'd love to see a picture of the card or of the damage because I can't really do a ton with just hearing the heatsinks damage and needs replacing but they could be saying that the fit maybe one of the fans is dying or maybe they've damaged it accidentally or maybe the I don't know I really have no idea punctured heat pipe or something if you tried to mod it I'm struggling to think of reasons why a heatsink would would be physically damaged if you just had it in normal use but send me a like post an injury link or something to a photo of the card because we can include it in the next episode and everyone upload it so that I see it next question Homer Thompson this is referring to last week when I kind of ranted about people wanting free stuff Homer Thompson said I don't want a free shirt but can I have a free puck well Homer good news NZXT is very accessible via Twitter and NZXT also likes to send us lots of pox in fact we have quite a few of them on the wall over there and I would it be really a shame if anyone tweeted at NZXT with hashtag please puck pls puck I that would just be really unfortunate if NZXT Zen box got a bunch of hashtag please puck tweets because then they then they might okay honestly they have sent out free parks quite often so I don't know try it tweet that at them and link to that into this video so that they know where it's coming from and NZXT good luck all right next question blessed man Fred says why don't you guys show off some crazy hardware builds like a lot of other youtubers not necessarily custom loop stuff there's a thing where I mean we could do that at like conventions and sometimes we do because it's built by someone else we just show it but our time is is so focused on testing and advancing test methods and processing data that doing fancy builds it seems like the kind of thing where I would rather give that segment of the market to someone else and let the other guys focus on it because if they can cover it well then great we don't need to compete in that space because we compete elsewhere and there's just not enough time I would have to reduce the quality of something else to do that but at a show keep an eye out what's next one serpent xsf says if I use the liquid metal on a GPI while using nail polish or electrical tape to protect surrounding areas how often would I need to maintain the graphics card with the electrical tape or a nail polish degrade over time so it depends I guess on the tape and the or the nail polishes but ultimately what you're using those things for is to protect the components from liquid metal spillover so the first thing you should do is not worry about either of those and worry instead about how much liquid metal you're applying and maybe even just do a test application like apply a known amount that you can replicate mount it pull it apart and see if there's any spillover without turning it on if there's not you don't really need to worry about the nail polish or the tape or anything else like that because all it's doing ultimately is protecting the components from spillover so if you've eliminated spill over that's first problem is solved now as far as maintaining I we have a it's gonna depend on the nail polish you buy if you're using nail polish I have some instructions on one of our articles that lists like specific chemicals that are ideal for a nail polish for this type of application and I will if I forget this remind us in the comments but I'll try and post in the description below what the composition is that we recommended previously because I don't have the chemicals memorized but but we did talk to some people and we got answers previously on what's best to use and that's what I would still recommend because I spoke to VSG of thermal bench and a couple other people about it and they're Bauer I believe so we'll I'll post that in the description so that you can see what we recommended as far as like maintaining tape or something like that captain tapes and good examples of captain tape aka thermal tape is really good and it can stand high temperatures like 100 T plus the power which one you buy so that's not gonna degrade just from the temperature because it's not gonna get hot enough to melt it or anything like that I have had to replace captain tape on thermocouples and on motherboards probably in a in an environment where they are exposed to dust I've had to replace them probably about at six-month intervals if it's not really exposed to dust it could probably go longer because the issue tends to be that tiny dust particles get in under the tape and then it just loses that adhesive quality over time not necessarily that the heat wears it out because they should be rated to pretty high temperatures that exceed the temperature the GP will be operating that or it's not even on the GP it's next to it so yeah in my experience because of dust about six months and then in my experience for nail polish we've only started using that for about a year on delayed CPUs and I have one that's been running almost the whole time and it's still fine there's been no degradation of it I don't know why there necessarily would be unless just running so hot that it's melting it but there should be enough of a spacing between the dye and where you apply the nail polish I really depending on the chemical composition the stuff we use any way which below has not had any degradation or anything like that it hasn't needed maintenance you could remove it with like rubbing alcohol or something but that's kind of a different story next question two arrows said how do you think the original out-of-the-box thermals guy feels right now does he still watch you I don't know do you do you still watch let us know how does it feel to have created the most successful medium on her channel for which we thank you by the way if anyone's not familiar with it it's in one of the sgn episodes I want to say 60 or 61 something like that but yeah that was a good one basically it was there's someone complaining that we or other people don't test CPUs for their out-of-the-box thermal performance to which I basically put some CPUs on the table and pointed this at them and said uh 21 degrees there's your out-of-the-box thermals so that's the meme if anyone doesn't know it that's what we came from fun fact that test was actually flawed because the heat the IHS is have some level of reflectivity and emissivity so this is not a great tool to measure them and our testing methodology therefore claiming that it is 21 degrees Celsius is in fact flawed and the out-of-the-box thermals may have been slightly different although to be fair for being realistic they are ultimately reflecting the room temperature which would be ambient which would be your out-of-the-box thermal so we've got a nice circular loop of logic coin there where it all works out in the end the next question silk monkey when did you have a surprising triumph ie reviving that hardware or a screw-up ie broke apart with ESD and what did you learn a really quick one that answers both of those questions where it was a sort of screw-up and sort of success in one go I had an AMD FX 9000 CPU I still I took it out of the system I'm using but it was in my personal system I have like garbage 80 through 50 in there now that was abused from testing and whatever but there was 9000 CPU in there 93 70 maybe and if anyone's ever taken and ECB's out of the socket the saw it's not particularly strong in the retention force so when you take the cooler off sometimes if you even if you kind of like work the cooler sideways a bit when you take it off it can just like pull the CP out of the socket and so one of the times when I did that the thrown paste had basically become glue by the time I removed the cooler and when I pulled it out the one of the pins from the CPU was left in the socket when I removed the CPU and so you're looking at it you look at the socket there's a pin in there and so that was the the screw-up and I don't I don't fully blame myself for that because I did try to remove it properly first the success was I just decided okay this motherboard is designated for the CPU and the other CPU will ever go in it and I put the CPU back in and applied enough pressure and the pin being in the socket was still contacting the CPU and if anyone's saying well but some pins are unused on TVs you're correct however I went and removed that pin with tweezers put the CPU back in and I had a memory channel issue so it actually wasn't necessary pin and just just sort of dropping it into the socket and then clamping it all back down it all worked so that would be the answer to that one I think I have couple quick ones left and then we'll have our patreon version of this so next one Carl says with all these tempered glass panel cases coming out like the coarser 500d with gaps between the panels for dust entry does this affect air flow or thermals with the case or is it minimal with a non-gaap side panel perform better air tight side panel cases are really complicated because it's always gonna tend to depend on the components you have inside of it and a case specifically the third will take v71 is a good example of this it has huge gaps in the side panels the top panel all of them has glass everywhere however it actually cools exceptionally well like I remember when we requested the case I had seen reviews elsewhere where someone did actually do a thermal test and it performed well enough that I was like that's someone most of that testing we got it in it was actually it was legitimate like it actually performed really well and part of the reason for that is because of the huge gaps that were like three quarters of an inch and all the side panels in the front panel so that it could actually breathe so yes to your point that does mean more dust will get in there especially depending on the pressure orientation of the system but positive or negative so so yeah more dust will get in through there but you're always got more dust for airflow ideally you have filters in the places of intake which is not the case for most of these tempered glass caps but if you can deal with dust it should theoretically be better for airflow there are instances where and we have a review coming up in the next couple weeks there are instances where a a set up with no top intake can't perform better for thermals gonna set up with or I should say no no top fans at all it's hard to talk about because like a product that's under NDA but I can give me the basics so I imagine a case with no fans on the top but there is a mesh on the top there's holes so in that configuration there are use cases where the CPU can be cooler with no fans up there and even no fan directly across from the CPU then if you put a fan directly across from the CP on the front of the case because of how the air pressure will pull some of that air up and out through the top of the case as opposed to air drafting down and in and into the CPU cooler and if that's confusing I'm speaking ambiguously on purpose we have review coming up eventually in the next couple weeks that will address it further so make sure you stay tuned for that but to answer your question typically the thermals would be better with gaps but it does depend on everything else dust will be worse though two more questions here Brom says Steve apologies it's been asked before but any latest ask John your answer about commenters for a little while and you mentioned you weren't planning on doing pre-release content we know you have some kind of professional relationship with - tech tips and I saw your float bird tweet Luke would you consider using floatplane or rather stick with patreon I think they can go exist I've talked with Luke first of all the misconception about their platform right now is that it has to have exclusive early access content because that's what Linus tech tips does and I think that's what Kyle does as well but it's up to the Creator so you could choose to do no early access like we do presently aside from the very occasional behind-the-scenes footage which tends to just go on a side channel anyway we don't really do early access I personally don't really believe in it I think it's okay to do like exclusive content on occasion like low-quality low production value behind-the-scenes videos that are basically going out to people who support us directly to say look this is a way to show you what's going on and it's cool stuff other people don't get to see and we're giving it to you because you support us financially however we're not gonna put a ton of effort into it because frankly there's not enough time and we know that everyone has an agreement including the patreon backers that it would be best for our greatest efforts to be focused on things like benchmarks and reviews not behind-the-scenes video so I think everyone kind of understands what's going on there but the point is I generally believe more in some exclusive content pieces like that that are more I don't know just it's like what you get on it if you bought a blu-ray or DVD you get kind of like directors commentary basically so that's more of what I believe in then early access so I have spoken with the floatplane team we don't have any plans right now I'm kind of waiting and we'll work on something later potentially but I mean I really haven't I have zero plans with them so yeah that said I'm interested in the platform it needs to develop more they have some good ideas and the main thing I think is that it's not all about early access its what does the how does the content creator want to use it so they probably haven't really put that in messaging yet because not a lot of people have I mean it's just Kyle and Linus so they don't really needed to message that to the community but yeah no plans presently but I've spoken with them so it's it's not even alpha or it's barely alpha at this point next question is from resident peanut who says what snowflakes out of the bed thermals well I mean we could ask the vet but I don't think that's no flake really likes the process required to provide that answer so thank you for all for watching if you have questions next week leave them in the comments below and we will have a separate patreon ask to be on video after this will be an extra couple minutes for those of
