120mm vs 140mm fans - What’s the difference? Probing Paul #28

2018-09-28
the master case each 500 M by Coolermaster sports dual tortor millimeter addressable RGB fans a USB 3.1 gen2 type-c port and 4 tempered glass side panels both sides top and front and the front can swap out for a mesh panel if you want maximum airflow it has a plethora of cable routing covers to keep things tidy too so click the sponsor link in the description to learn more what's up guys welcome back to Pauls hardware this is probing Paul episode number 28 this is a monthly Q&A video that I do where I answer the questions that you asked me last months it's a pretty straightforward premise last month was episode 27 so now we are on episode 28 here is a look back through the Oh down the hole of time to the past probing Paul's and with that said let's just get right into it with the first question Clarion Hatake asks hey Paul wanted by two fans for my NZXT s340 I've two empty spaces in the front for two 140 or 220 millimeter fans what is the difference other than these size for these fans this is a good question I will address it here with some visual aids so this is a typical hundred and twenty millimeter fan for a computer this is 140 millimeter fan it is larger I should start out by saying that not all fans are made the same so this is an NFA 12 X 25 pwm fan from Noctua and they put a lot of time and effort into designing this to make sure that the fan blades are very very close to the ring around the edge so there are factors with fans that you should check such as CFM there as an airflow statistic as well as static pressure which is a very key thing to look at if you're going to be using the fan with a radiator or a thin stack behind it that said and ignoring the differences between slight variations and spec and performance from the fans themselves if you're just comparing a hundred and twenty millimeter 240 millimeter there are a couple of general things that you can say about them this is larger yes so you need a little bit more space in your case and you need to have mounting points for these but larger fans will generally be able to move more air so bigger fan moves more air and they can often spin at lower rpms while moving more air which is why the rage for quite a while was like larger fans like hundred and eighty millimeter or 200 millimeter fans those are less practical because they're even larger and so you do need a large case to support them but that's the basic difference between them if you have 40-millimeter mounts I'd recommend going with 140 millimeter fans simply because chances are you'll be able to get a quieter experience but again remember that not all fans are designed the same the motor is also something to consider so take those specs into consideration and then get a bigger fan if you can fit it in your case next question from APEC hey Paul can we have a power wall update please want to know my thoughts and what I think as well as efficiency and power savings now that it has been in for a few months my solar installation video I got a Tesla solar array as well as a power wall and those videos did quite well I had lots of people asking me about them so I am still planning some follow-ups on them I apologize that I have not done them quite yet but there are a few factors contributing to that one of them is that I was gone for a good chunk of the summer when I first turned the power wall on I was gone for two weeks there at the end of the summer I was gone for two weeks again also the temperatures keep changing and fluctuating so I feel like I could give an assessment right now for like this one month of summer but to be a little bit more thorough I feel like I need a little bit more data that said I can share at least this with you guys right now Southern California Edison likes to send guilt-trip letters to its customers comparing your energy usage with your neighbors and I used to get this thing that was like here's your efficient neighbors and here's uu inefficient piece of garbage not much energy you're using never mind the fact that I work at home and like I run something of a mini studio out here in my garage and stuff but here's the more recent one and now we can see here's me compared to my efficient neighbors and way better now I got the great smiley face there and if you look at the comparison here for the past few months you can see my March April May where I was kind of generally above the usage of everyone else and then June July especially in summer when everyone else's you should spiked mine stay low I was still using power from the grid size did stuff to pay a power bill during those months but it was way way better so I'm saving probably a hundred two hundred and fifty bucks a month right now but I have one follow-up video coming where I am going to clean my solar panels because they really need to be cleaned right now and I wanted to do kind of a before and after comparison there and then yes I'm planning a final follow-up video where I kind of give an assessment of the entire thing it'll be kind of a one year later thing from when I initially signed up to get everything installed next question from Joey Gil Holtz since the NDA will be over next month why doesn't Vidya get away with increasing GPU prices year-over-year including the founders edition price up facin with tanks performance in mind do you think they're going to lose sales to much more reasonably priced Pascal cards yes they are I think that's kind of their plan it's a weird situation right now because everyone's like oh the Archie x-series is too overpriced by 10 80s and 10 70s and everything instead and NVIDIA is probably like that's fine with us we make money either way but more to your question of how it is in video get away with it and I think it is a serious long-term marketing scheme as well as like you said obfuscation a bit of manipulation going in there too I have mentioned this back when an Nvidia first launched the Titan which was $1,000 graphics card at the time when the most expensive graphics cards were maybe five and six hundred bucks each they launched the Titan at that $1000 price and then they said don't worry it's like a prosumer product it's made for people who are using it for scientific applications and stuff like that and that may be true to some extent I can speak somewhat an totally from my time back at Newegg when the original Titan launched to say that those sold those did not stop selling they were not a Halo product that set and every once in a while one of them would get sold but a lot of times they were sold to universities and institutions that were using them for FB compute performance and stuff like that at the same time though that halo product that Titan class graphics card was used by gamers and it was put in like the highest of the high end gaming PC's at the time so there was sort of this creeping up in the past five six seven eight years from 5 $600 graphics cards to the 1080i which was like 650 $700 at 1081 at when it launched was a was over $600 as well and he could even point to the launch event for the RT x-series when Jensen was up on stage walking back and forth talking about the power and performance of the new graphics cards and very vague terms but what was he comparing it to $68,000 workstation clash class machines which does a couple things one gives you the impression that the power of this card is somehow equivalent to those you know crazy expensive stuff that the price classes using and makes you think like up maybe twelve hundred bucks isn't that bad and you know I'm not saying you all thought that most people were like oh my gosh twelve hundred ollars is very expensive but it's a long-term process of getting people to pay more money for stuff and I think constantly valuing the new graphics cards at higher and higher prices just slowly erodes people's thoughts of like here's what a high-end graphics card should cost versus now what should a high-end graphics card cost and point case in point here this is a twenty atti for a thousand or twelve hundred bucks you've never had a graphics card that was a consumer mainstream gaming graphics card that cost that much but prior to now everything was a Titan I was like oh that you could use that for gaming but you can also use that for other stuff too and that's why it cost so much this is just another step in the process of getting people to pay more money for graphics cards and the economists and and whatnot and the audience can argue that further but that's I I agree with you I guess this is my final comment on that next question from phrase M why do we never see a new major company that develops CPUs or graphics cards there's always big guys like Intel AMD and NVIDIA that dominate the market no one challenges them short answer here is that there is a massive barrier to entry when it comes to designing stuff like integrated circuits CPUs GPUs they're incredibly complex there's other factors that play into it such as intellectual property rights and patent law and since that's international it's just very complex you need like lawyers you need engineers you need very smart people it costs a lot of money to pay those people and therefore there's just very few companies that actually have the backing to manufacture something like this also bear in mind there are chip designers and their fabs the fabs are where the chips are actually produced and then you can have design houses that then go and take their designs and work with a fab like tsmc or Global Foundries AMD for example used to be both a chip designer and had their own fabs but they spun off their fab just GlobalFoundries back in the 2000s not going to dive down that but that's a short answer to your question it's very very very expensive to get into this space so probably not going to see any new players in this space for the time being unless you look at China maybe China might come through with that but I believe they have government's help next question from Elvis Clark hey Paul of the channel keep up the great work thank you thank you very much Elvis he's built his first gaming PC and he built it during the mining craze so graphics cards are very expensive but he's got an ASUS Maximus nine code motherboard is 7700 K 16 gigs of g.skill memory a crabber gauge seven quad Lumi and a geforce 1050 TI GPU which is an adequate GPU but definitely a little underpowered compared to the rest of the rig NZXT elite case and he's got a very nice monitor here monitor is the asus rog Strix XG 3 5 v q which is 35 inch curved 34 40 by 1440 ultra wide and it's got free sink support 730 bucks you can get this for right now this is just a testament to like how much cheaper free sink monitors are because this is kind of in the same range as my Easter predator x34 back there but a very nice monitor and definitely you want to pair this up with a free sink capable graphics card and you can upgrade from your 1050 Ti so I'm over on PC part picker I'm looking at video cards and I'm only looking at rx5 80s as well as vague at 56 is in 64's the RX 588 gig which is what you would want to upgrade to is 220 bucks and that's very reasonable that's much cheaper the retail price for this is supposed to be 250 so it's great you can get at that cheap that said this isn't gonna be a huge upgrade it's a pretty decent upgrade but not a huge upgrade over your existing 1050 Ti so if you want to get a little bit better you can scroll down to the Vega 56 options which you can get as cheap as 420 dollars right now just reality checking yes this Radeon rx 580 is available for $240 and there's a $20 million rebate card also right now you get a game pack with these AMD cards which includes assassin's creed's Odyssey strange Brigade and star control origins maybe you're interested in those games maybe or not but it's cool that you can actually recommend AMD graphics cards for reasonable prices now Vega 56 the cheapest one I found for the time being is 420 dollars also a very good price for that card the other thing you should probably look into is the used market just bear in mind with AMD cards in particular there's a very good chance you're going to get a card that was used for mining which might be perfectly all right just reality check see if you can some additional information about the cards use from the used cell you're buying it from but hopefully that gives you some options for now and start taking advantage of that awesome monitor you have just a couple questions still left fsx toute asks i want to build a pc with a 2200 g which is an AMD APU eight gigs of ram and a 240 SSD could I use these in a finished builds to edit 4k video Wow so short answer for you is yes you can edit 4k video with that setup the longer answer is you're gonna have kind of a painful time I think you're actually gonna have the most difficulty with your SSD you're gonna run out of space because 4k footage takes up a lot of room and if you're editing off that single drive it's just gonna be very slow and choppy so yes it's possible to do one thing you could do is take that raw 4k video and then re encode it into Sena form files and then use those as proxies while you're editing Sena form is unencoded which means it's much simpler to simply read off of the drive and display it on screen so it's a lot faster when you're discovering around the timeline and actually doing your edit that said you're looking at a pretty underpowered system for 4k video editing so you could do this it's just not going to be the best experience for you but this is also a nice starter system so if you need something to edit with right now you could upgrade that 2200 g2a six core or an 8 core rise in the processor in the future you could upgrade here memory to 16 gigs or 32 gigs in the future that would be a big boost in performance and of course you can add more storage higher capacity SSDs and especially hard drives for massive long-term storage for all of your raw footage and those will all be very helpful upgrades for an editing system just like this so best of luck to you in the future and I hope that advice has given you something to go off of last question here from John and this really isn't a question it's a comment from last month and you just said finally a video without music when talking thank you and 22 people thought enough to upload that comment so I thought it would end this video with a question for you guys for a video like this where it's just kind of a talking had me responding to questions or whatever should there be background music because honestly it's more work to add background music into any given video so just wanted to get your guys feedback on that whether you appreciate the background music whether you think it just shouldn't be there are we wasting our time by editing that into our video edits that we do because that is all the time I have for now for a probing Paul episode number 28 thank you so much for watching this video hit the thumbs up button if you enjoyed it and leave me questions in the comment section down below so I can answer them next month in next month's probing Paul it's been good to have been probed by you all today and we'll see you in the next video
