everyone welcome back to another episode of ask GN finally back from CES working on some follow-up CPU testing for KB Lake and other CPU so do stay tuned for that the questions as always if you have them leave them in the comments below I'll try to get them for the next episode this week we have a couple that are wordy but I think we can get through them somewhat quickly I'm still waiting on responses from intel on a few previous questions we sent them they've been a bit slow getting the answers really anything that they do acknowledge all of the questions I guess that's a start before we get into the questions this video is brought to you by cyber power and there's cyber XL gaming PC which has the invertible motherboard tray layout and a couple of other cool features with the polycarbonate side panel and lights of course check the link in the description below for more information on that the first question this week is from Tim Tom T Chris who says question for Steve many motherboards I have different connections like for your mouse USB stick or other device audio ports etc does the quality of signal suffer when devices are connected directly into your motherboard into your keyboard rather does a mouse latency increase USB Drive transfer speed and decrease audio quality worsen is it better to connect to your motherboard instead the one I haven't tested here is USB Drive speed that'd be kind of interesting but generally the so those ports on keyboards and know what you're talking about they're normally called pass throughs so the Logitech I think that Jesus 710 plus or something a lot of them but that one especially comes to mind use two USB headers out of the keyboard and one of those connects into a slot and your motherboard and basically just passes it through to the keyboard so you should have full bandwidth that shouldn't be a problem at least if you're doing it that way where there's two USB headers on the board the keyboard connecting into the motherboard then you you do pass that signal through the potential I suppose downside would be latency technically if you plug into the keyboard it's got to go through one extra layer to get to the motherboard so there could be an increase in latency there whether or not it's relevant I haven't actually tested that would be kind of interesting but I don't have the tools to test that and in a way that would be repeatable and accurate one thing not just kind of in general I do prefer to plug my mouse and my keyboard directly into the motherboard and then if there's a pass-through on the keyboard I'll use it for something else I have had issues with several keyboards in the past where they'll drop signal now and then to the USB device so I would not want that to happen to a mouse while I'm gaming because you just lose signal for a second and have no movement well you also don't want to happen to a USB key so it's not a lot of good options there most of them are fine truth be told in terms of connectivity but I've had enough issues with some of the earlier samples of the usb pastors on keyboards that I just generally try to avoid them for anything critical at this point other than maybe a USB key that's not gonna do a whole lot of them transfer files for a few seconds to answer your question I don't have a hard number for you latency would increase because you are going through another layer if if not digitally definitely at least physically you've got more travel but again that could be totally insignificant and from sort of just hands-on use I don't know that I've really noticed any Mouse speed decreases from connecting to the mouth of the keyboard but just because I wouldn't want to drop connection and because I guess to some extent maybe I was gaming the superstition or something I would rather have my mouse plugged directly into the motherboard the next question is from apple maggot that's a lovely thing haha a boo maggot says question I have a Toshiba laptop l 675 D that has failed and needs a reflow or reball of the video chip what is your experience with this xbox360 had the same red rain of death that was solved with reflow and third-party cooling and has since turned into a cottage industry due to laptops having inferior cooling solutions there seem to be four solutions the oven reflow heat gun reflow professional reball with new graphics chip for $120 on a 17 inch laptop so Louis rossman I think as his name has a really good video on this and it was directed at Linus from - tech tips because Linus did a reflow video some time ago Louis is an experienced repair technician mostly works on Mac units but has done enough with reflowing things and actually soldering things to fix them to know what's up soldering and rhe flowing normally you're going to reflow something because the solder has micro fractures in it as Lewis said it's not a permanent solution this is something that if it works you get a couple months out of it and then the problem comes back to a more permanent form so this I would not recommend using an oven to reflow your video card or your GPU or laptop one it could go wrong and two if it works it's temporary so if there's no other action I guess you could do it to try and get data off of there but you can still just pull the drive anyway hopefully and just recover the drive through an external enclosure connected to a PC or something like that so I don't know that I would really recommend reflow in it maybe maybe if you have no other good options and you need to get an extra couple months maybe one to three months out of the thing before you upgrade maybe it's worth doing but check out Lewis Rothman's video and it's he's got a pretty good one and Linus actually revisited him in New York City where he works and they did a follow up video where they actually tried to reflow some stuff or properly restore some some equipment so that's a bit educational but generally I would not recommend it my experience with it is very little and I am NOT an expert on it and I don't think that anyone who isn't an expert on it should be doing it either because really you're only good option is to actually properly replace the chip and that's normally not worth it on a laptop unless it's an MX M card anyway that you can kind of just swap if you can get a professional to do it like you're saying for 120 bucks and they're actually going to properly reball the GPU rather than reflow it then that's not a bad price I don't know how old that laptop is but I might be worth considering I would do that before sticking it enough and I think exiled storm asks my question is what is the difference between an OEM CPU 6,700 cavers om 6700 K and why do they usually cost more money than a standard version so the OEM CPU is normally I think on Amazon or Newegg one of them recently I was talking normally when it's listed as om the I don't know about the case keys for skylight because they don't come with CPU coolers but traditionally om has meant that it they removed the box anything in the box other than the CPU and I sell you a straight CPU and my idea is that it should be cheaper not more expensive kind of like how any other OEMs of anything like Windows is going to be a bit cheaper because idea is that it's sold to system integrators who then pass it on to a customer and can do so at a reduced cost for the product the 6700 case specifically I haven't looked into but generally it's an absence of a CPU cooler and absence of manuals or the box and things like that don't think it should cost more because it's not going to give you anything special the next question is well and quick note if you saw it on Amazon their prices are all over the place anyway so that might be why a next question is from Rodney Rogers he says how easy would you say it is to revive a not working graphics card how can you tell it's the dye and not something you can repair with soldering I would say that it is very not easy to repair now working video card this goes into the this the reflow in question just pulling out a soldering iron and applying it to parts on the GPU isn't gonna fix it especially if it's the dye there has to be something really specific that you can recognize and understand how it works and how it's connected to the PCB and what its job is to to make anything work with the soldering iron so generally with video cards unless it's something really expensive you're out of warranty the manufacturers not going to help you at all retailers not going to help you at all if that's the case and it's maybe a six or seven our video card I guess would be worth looking into I have no idea where to tell you to start because it's not what I do but I would have to imagine that pain a professional to do that would cost close to a new card and probably had just be better to get a new card so the answer how easy it is to revive a dysfunctional card would be not easy the best thing to do probably is to just do some basic troubleshooting so plug it into a different system see if it works it doesn't work that well try different ports as well hdmi displayport TV i use all of them see what happens you can do some testing with the different monitor just to make sure it's not the monitor that's broken those are all the things I would do first after that point if you're really desperate and there's nothing else to do it might be worth opening the thing up and seeing if there's anything really obvious and that's wrong like for example if the GPU heatsink is applied incorrectly or something like that and the card is just refusing to function because it's running too hot too quick or something but I yeah again not really worth sort of reflowing or soldering anything unless you really know what you're doing and can identify the problem quickly and I can't that's not what I do so the next question is from super goody I'm planning to build my first PC soon I'm planning to use the i3 6100 concerned about my options question KB Lake has the 1151 socket like skylake so could you use a KB Lake processor on a motherboard designated for skylake I've seen that there needs to be a BIOS update if one were to do that how would I go about that I plan to buy the be 150 I gain Pro AC wood MSI released an update for this that's on MSI yes you can sort of mix and match cable akin skylake processors and motherboards to an extent check the board manufacturers website a lot of them have been pretty eager in releasing BIOS updates MSI included for some of their boards I've seen them for MSI ACS gigabytes I think as rock as well a couple I'm sure almost all of them at this point have done that they released BIOS updates they are for specific motherboards so you can't just take a BIOS update from MSI's what our gaming Pro carbon or something and apply it to whatever it is you want to buy it has to be specifically for that board it would be listed if you type in what do you by MSI be 150 I game Pro AC drivers that would take you to MSI site click the support button download go to BIOS see if there's a BIOS update that has the compatibility patch that you want and then you would download it and install it through this depends manufacturer manufacturer you install it either through an exe that you just run from the desktop or you put it on a flash drive restart boot into BIOS go to some easy flash utility pick the drive pick the file and tell it to load and then it will flash your BIOS it needs to be compatible you can't lose power during this because anything like that would potentially brick the motherboard and you might not be able to get it to turn on again keep that in mind it is pretty easy so I don't don't want to scare anyone away but just make sure everything looks good the short answer how do you know if a board will support it check their website they will definitely tell you if it does support any kind of forward compatibility with KB Lake because that's a feature to brag about so they would let you know it's not hard to do if they do though the next question is from name I can't pronounce will just go with my cutie coca I suppose I apologize question is I liked I would like to know if aftermarket blower GPU is like MSI arrow and the issues turbo are any better than referenced founded edition in terms of cooling and sound Emma didn't blow our Styles because of my case this I'd like to know if it's better to go with aftermarket coolers or reference and yes so it depends on the fan and the heatsink because the blower cooler itself based there are different types of blower fan just like there are different types of radial fans and there gonna be a different qualities the founders edition fan to give NVIDIA credit where it's due is actually pretty high-end they used a good fan it doesn't cool very well in terms of the rest of the GPU but it's a good fan the and when I say it doesn't cool very well I mean compared two aftermarket solutions like the dual radial fans or axial fans rather and insert so is it good it depends on you look up a teardown for the cards you're looking at the MSI arrow I don't really like to be honest but if you look up a teardown you'll want to look at the heatsink itself so as the heatsink better than or equal to the founders Edition heatsink if it is then and it's cheaper then it might be a better card to buy just because it's cheaper has the same cooler heatsink you want to pay attention to finding city doesn't have a copper base plate or aluminum does it have a vapor chamber or copper heat pipes or anything like that and they'll tell you all of those things or they should in their marketing materials and then you just have to find sites that have torn it apart I haven't torn apart either of those specific cards I am NOT a big fan of the MSI Aero card I did use that but didn't tear it down well I guess we sort of didn't tear it down with the Seahawk the Corsair an MSI Seahawk mostly the same card but yes so yeah they can be better or worse than founders edition absolutely it just depends on if they used a better or worse fan and heatsink and the fan for the founders editions pretty good so if they have a better heat sink on the aftermarket card it might be better but the fan that's gonna be harder to beat a Massiah it's not a big fan of Asus I have no experience with that specific card and then oh also it's kind of worth noting this the PCB layout is also important so if you're using basically a reference PCB with a modified cooler it normally means they've gone with a cheaper cooler cheaper fan cheaper heatsink and they've stuck with the Nvidia reference PCB if that happens it's gonna be a worst card overall in terms of cooling specifically unless they run a higher fan rpm profile which is definitely possible and the piece of you if it's aftermarket they might have added to the vrm so it might have more phases if that's the case you're spreading heat out over a larger area which is important and that could reduce your temperature as well so it just depends on the specific card there's no yes X is better than Y for this question next question is motherboard airflow is it a myth for some water cooling builds having the radiators in some locations without case fans it's clearly going to give you great temperatures on CB and GPU but no real airflow over the vrm is etc on the motherboard where you'd usually have case fans blowing air over them and then goes on to say that they're building a water cooling system and that's the concern yeah there's it's not a myth motherboard airflow matters but VRMs can get really hot and go over a hundred C easily and pretty much every case on a motherboard that doesn't mean you should he shouldn't try the to that but I generally wouldn't worry if you're doing some serious overclocking maybe put a fan pointed directly at the vrm is depending on how serious the serious overclocking is because if it's actually really extreme like builds I'd would do then you're gonna go with something like with liquid nitrogen or dry ice or something like that or Peltier cooler but yeah a lot of the VR M's like for the was that board reviewed the RS game in seven the Z 270 board the VR m4 that you could probably run it without a heatsink even on the motherboard because they're really not going to get that hot especially with the new Intel stuff they just don't tax the tax of erm that heavily so I would not worry about it too much now if you're putting your system in a box where there's zero airflow and your fans aren't gonna push any air anywhere near the motherboard I'd probably put a fan in there pointed at the board just to help get rid of the heat even if it's at a low rpm like 800 rpm just because sitting heat makes me nervous in a computer and the memory is going to generate heat the PCH generates Heat when you're doing i/o and of course the vrm around the cpu the GPU vrm on the motherboard all that stuff generates heat at some level so having still air is not something I like I would put a low rpm fan in there and then hopefully that can just kind of keep it circulating enough that your liquid cooling radiators and their fans can get rid of whatever heat is sitting in the case but yeah not a huge deal but definitely not something to just completely ignore in all use cases either so that is it for this episode there's a ton of CES coverage on the website gamers Nexus not net
