what's up guys Jays $0.02 here and today we're going to talk about a piece of your computer that often gets overlooked and quite often I hear people say yeah you just get a cheap one that's not gonna really matter well in this case it actually can today we're gonna talk about case fans and radiator fans and how much of an improvement they really can make in your system with its aluminum bezel solid construction and adjustable base the vast 35 inch ultra wide 100 Hertz VA panel for mass drop offers performance at an affordable price learn more about this drop by following the link in the description below so what we're looking at right here is my in windy frame build that I did last year well getting the year before I think technically whatever doesn't really matter this was my personal computer until I ended up bringing skunkworks back home so it's got two Titan XP or little piece so it's the biggest Titan of the ten series that was made it's in a parallel loop a single loop with dual rad so to 360 rads by ek we've got our singularity computer computers reservoir we've got our single block right here for the CPU and vrm so it's a mono block for our rampage motherboard and it's got a 70 900 ex in there so it's not a crazy system in terms of like core count and all that but it's certainly no slouch either it definitely gets the job done with 20 cores well 10 cores 20 threads whatever but the issue with this is although this is a very tubular like cubular type of frame here it's very open there's no fans on top it's not sealed off in any way if you look at the temperatures right here we have had heaven running now for about 45 minutes and you can see the temperatures are at 54 and 55 it will bounce between 54 and 58 degrees right now depending on the scene and the crazy thing about this is you may know heaven does not stress the system nearly as much as games can so what I saw when I was gaming on this is that my temperatures would reach the low 60s in playing things like battlefield 5 and stuff entirely too hot for a water-cooled system especially one that it's got an open chassis like this that should not be impeding air flow in any way the top right here is if I had to make a guess I'd say this is probably about 45 maybe even 50 C like it's extremely hot to come out of here when you touch the metal the metals heat soaked it's heat soaking in something that is not sealed which is a problem so the polaris fans that I'm using on here they're in when Daisy chainable fans that are 12 volt RGB so not addressable they're just a standard 12 volt RGB that's hooked up to the asus motherboard being controlled by the AI suite now they're running a hundred percent right now so these temperatures that you're seeing the 54 and 55 c is with the fans on the bottom bringing cool air in there's plenty of gap down here for it to get air from underneath the chassis it's bringing cool air in and up through the top and this is also bringing cool air from the front like that so the airflow is kind of like this and the idea was if we've got all these fans pushing in it will give us positive pressure to push the air out the problem is you cannot feel any air flow in here the polaris fans although greatest case fans and daisy chain able making it easy to have one wire able to connect like six fans and i think it's eight actually i don't that doesn't really matter the point is they're not good with static pressure and overcoming the resistance of the radiator fins so what we're getting now is the air is just kind of coming through the radiator very slow and stale and what we're getting now is a convection effect so what we're dealing with right now is this is heat soaking to the point to where it finally gets hot enough to where the air rises and pushes itself out but it doesn't do it nearly efficiently enough and what's happening is the radiators cannot get enough air flow through them meaning that we're getting this heat soak problem in fact my cpu right now is even sitting at 57 C with heav'n running no that's not super hot but again it's water cooled and it's not even that big of an overclock it's like 4.2 gigahertz because anything higher and it was starting to get way too hot now no I have not lapped the CPU and I have not done a deal it on the CPU which would probably benefit it quite a bit but how hot the GPUs are getting to are telling me that we clearly are having a cooling inefficiency so what we're gonna do today is we're gonna try a couple of things one I just want a sort of proof of concept that if I can get this hot air out of this case that it will help the overall cooling makes sense right if the hot air is trapped in here that's causing a heat soak it means the radiators aren't efficient at this point then the hot air that's just sitting in here soaking everything is causing the temperatures as a whole to rise so I'm gonna start by taking a 140 millimeter fan this is one of the the new fractal Prisma fans I'm just gonna set it on top right here plugging the to the motherboard to let this assist with the exhausting of air to where this fan is pulling a good chunk of the hot air out rather than forcing the positive pressure coming through the rads to do the job with a convection assistant or a natural convection assistant shut up shut up ah well the whole ring turns there we go that'll do it now what we're looking for here before I go through all the work is to see if this is gonna drop the temperatures at all because if it doesn't well then I don't know at that point it's at 50 51 right now so after only being like 60 seconds in front of it it's dropped like three degrees up 49 15 all right so proof of concepts working more air means cooler who would have thought so we're bouncing around between 48 and 50 right now yeah so this is actually a good proof of concept because you turn this off this fan is not actually pushing air through the radiator it's just lowering the temperature as a whole inside because the fans are still kind of working as resistance so the air is still all gonna be able to go through the radiator as fast as the fan can push it so this was probably speeding up those blades a little bit and we saw a good 5 C reduction maybe even a little bit more than that so we're gonna go ahead and push forward now with changing out those front fans possibly the bottom ones as well and seeing if we can't get these temperatures down I'd be fine with anything in the mid 40s but Pascal sitting in the mid 50s on water that's way too hot that means something isn't right what's a forties high forties is better than mid to high 50s which is what we were seeing and like I said in a bedroom environment that's was hitting the 60s so all I did was I changed out the in wind fans for the ek VAR DARS in RGB now yes I'm well the way that they're louder as you can hear yes I'm well aware the different blade design and that they're spinning faster obviously that's the point of this video is to show that by adding more rpm and more static pressure and more flow through these radiators our temperatures greatly increased what the efficiency of the radiators increased the temperature decrease which is kind of what we were looking for here the polaris fans are not good radiator fans and and when Amy told me that but they were pretty and I was like they're daisy-chained and it's fine I've told people before you could go with more radiator surface area in this case to 360 rads and just go with some slower fans and you'll be fine but the problem in this particular use case is the fact that what I said is partly true you can use cheaper fans fans that are not going to be you know 20 30 bucks apiece and just use more radiators and get the same benefit of cooling without the noise and all that stuff as long as your chassis has fans that are exhibit assisting with the exhaust the problem is the radiator fans who are responsible for not only pushing air through the radiator but also the only air flow in this chassis whatsoever so it was just too much for the players to overcome the resistance of the radiator fins as well as having to deal with the exhausting of air with even the assistant the assisted effective convection with heat rising it just isn't enough cuz he doesn't rise until it gets hot and then obviously well he just hot right so the air doesn't rise until gets hot enough for convection to become a thing which at that point it's already too hot for the components also too if you're if you're commenting like well you sure to use the different fan with the steam specs to test know that that's not what we're testing we're testing if we can if we had the same CFM as we had before we would have the same problem so that would have done nothing so in this case because of in this case get it so in this case our sacrifice has to be noise to overcome the amount of airflow and stuff so if the radiator was up top however and this air was coming in to the front and then just going out the top like a case would be like a normal you know rectangular case then the Polaris would have probably performed a whole lot better than what this radio drew on the bottom the problem is all the heat coming off this radiator both of them actually is pushing into the chassis which is causing some of that heat so by flipping a rat up here where to fix that problem not possible in this particular chassis so as you can see with the test still running we're sitting at 47 and 49 respectively so heck of a lot cooler than it was before at the sacrifice a little bit of noise so the whole point of this video was just to show you that there there is a point of where the fans in the speed and all that does matter even with the amount of radiators because if I had had another radiator on top let's say had one in the front one of the bottom one on the top it would be the same issue in fact it could have potentially even been a little bit worse only because if we were still using Polaris fans on a top Brad with on the front and on the bottom it still wanted to be moving enough air we'd have added a little bit more of a choke point in my opinion and then this would it ended up becoming just as heat soaked and the temperatures would have risen just the same it just might have taken a little longer to get there so there you go at the case you guys haven't seen in a while and a build that I'm very fond of and I don't want to take apart but it's got some damn good pieces in here that I could use in other bills it's got an M about to drive it's got the rampage motherboard on X 299 and of course we've got the two 360 rads and the class 2 Titan X bees it's like wouldn't be funny if I took these all out just to build another build which means I could've just left for this one together all along yeah whatever I digress you know give it to my 9 year old sorry guys I'll see you in the next one
