pc top radiator as intake

The GPU outputs the most heat into the case but again, most of that gets ejected by the exhaust fan. Components running 5-10 degrees Celsius more because of bad airflow aren’t going to last as long. Also, if you have three intake fans, this whole debate is pointless, that's more than enough airflow even for full air build on low RPM. This is also why I'm not a big fan of CPU watercooling, because it's the GPU that outputs the most heat and does the most noise. Top fans exhaust. I was going to go straight across for water flow, but my friend pointed out to me that the inflow of water should always be at the bottom of a radiator so that it fills up the bottom and then overflows into the outlet up above. Utilising the proven XAIR VE/VF OTR Intake Body design we redesigned it with a recess in the bottom to allow the factory radiator cap to sit up inside. Hot and cold air are sectioned off in a top-v-bottom layout. That's my problem because using it on top is the only option for this case. It's really weird. This isn’t a question really of right or wrong, just more of which you prefer. Unfortunately, that effect is small and will only last a few minutes with a top mount radiator as intake. Exhausting air form inside the case through a radiator may give you a few degrees higher CPU temp in games because GPU makes a lot of hot air. This ensures the pump is below the radiator and that air will sit at the top of the loop and not be sucked into the tubes. You’ll end up with a bunch of hot components real quick otherwise. As long as you have extra intake from side/bottom you don't even feel it. 12 Aug 2019 at 11:57 #4. ttaskmaster. If you read the install manual for the AIO cooler, it would tell you the same. Flip the fans. It’s supplied with a pair of huge 200mm front intake fans, making the top radiator location the obvious choice for a 240mm CPU radiator expelling hot air out of the top … Anyone is welcome to seek the input of our helpful community as they piece together their desktop. You want them as exhaust. https://www.youtube.com/watch?v=QjYli6itP38 - It doesn't really matter much in terms of cooling, https://www.youtube.com/watch?v=YDCMMf-_ASE - Everything people think they know about airflow is a joke :) "Oh, I forgot the tape. PC cooling: there’s a right way and a wrong way. A heatsink spreads that heat over a large surface area and blows air on that area. I got much lower temps (13C) having my top and front (radiator) fans as intake with only a single small exhaust fan at the back. In my new rig I had to front mount my rad for an intake. I was watching some youtubers put the radiator in front and have it serve as an intake instead of exhaust. Mostly depends on a few things but for me when I had a top mounted radiator I had it set in a pull configuration exhausting air out. I think the way I have my fans set up my GPU is slightly cooler. I was using a 280mm radiator in the front initially, I then swapped for the 240mm radiator to test my theory. "Dude you're fucking retarded, you're supposed to flip the fans and push air out of these case through the radiator instead because hot air rises, blah blah blah." The internal case temperature goes up as you dump CPU waste heat in and the H115i water temperature (and everything else) will be warmer than if you exhausted it directly. positive pressure will build in your case and the fans will have to work harder. Any warm air being blown into the case isn't going to heat up the CPU, especially if the CPU is the source of the heat. I wouldn’t say it doesn’t matter. This way the hot air isn't in your case. yes the air will get warmed up a little by the gpu and whatnot before it goes through the radiator, this is also not a big deal. 2010-2015 5th Gen Camaro runs the same Chassis/Engine/Driveline platform as VE/VF Commodore except the Radiator Cap is in the centre instead of offset to one side. Just curious, I'm not an expert at thermodynamics tho since I barely passed Physics 12 back in hs haha, but wouldn't the front intake fans circulate that hot air coming from the top radiator into the exhaust fan in the back? PC components heat up to temperatures like 50-80 degrees, that's quite normal. I guess anything can be OK if you have enough fans, but isn't this incredibly* inefficient? cant you mount your radiator on the back or on the top? People crack me up in here sometimes. I … The front only has … Thanks! Planning on building a computer but need some advice? 2 front and 1 back. Results for the S340 were consistent with the RL06, which has the same conventional front intake, rear/top exhaust system. 280mm radiator top-mounted, pull-exhaust configuration. Just make sure your exhaust fan in the back is at full speed to compensate. However I've been seeing alot of builds with the radiators as intakes, on the front of the machine usually. If you blow the heat back to the cpu, you’re what, trying to just create a circle of heat? exhausting out the top makes for far better airflow in your case, pun intended. some cases have dust filters all over so it wouldnt really matter but you'd be cleaning off the top filter a lot. you have fresh air coming in from the front. Someone who overclocks very high, needs the coolest CPU temperatures, and doesn't mind the noise too much will benefit from having the radiator intake from the top. Exhaust, you shouldn’t even consider anything else. The 240mm radiator, however, is thicker and has tighter packed fins. Results. https://www.maketecheasier.com/intake-exhaust-fans-airflow-desktop-pc But if I were to instead use it as an exhaust fan, I would be blowing hot air into my radiator which can increase the temperatures of my CPU. On a side note, I have a deepcool matrexx 55 case and the front 3 are intake but for some weird reason which I'm assuming to be pressure related my top most fan of the 3 pulls air out instead of pushing it in and yes I've checked the direction of rotation and the arrows on the fan and they're correct. But if you do this, wouldn't you ALWAYS want the fans to be exhaust? The radiator needs to be put in a way it is not impeded by any device in the system to ensure you get the most performance out of the cooling system. Edit: Wow! Simply turn it one way, run a few bench marks then compare it to the same temperature post benchmarks the other way. The CPU will be measurably cooler when gaming if the AIO is intake, dude. Side-mounted fans can be intake or exhaust, depending on the setup. My question is if I'm limiting airflow and/or cooling by going with either of these and if one is generally a better option than the other. Manage Your Cables and Other Obstructions. everyone saying 'heat rises' is just parroting this common idea but convection is negligible in an active cooling context, the air is far too busy being pushed through your case by the fans. The cpu is getting fresh, cool air. This is the place to ask! How were the GPU temps? Your brother is right. For most mid tower cases, you will preferably want around two or three fans on the intake on the front side of your PC and one exhaust fan. right now you have way more intake than exhaust so you have positive pressure in the case, balanced is the way to go. While the top becomes intake then. However, you want to consider if a single rear fan will be capable or removing the GPU and CPU waste heat you are likely to see in mixed load conditions. /r/buildapc is a community-driven subreddit dedicated to custom PC assembly. Intake on top is a no-no unless its the only option like it is for my 280mm AIO in the PC-O11D. I personally would do them as exhaust but it will only make a few degrees difference maximum. 6700K + 1080Ti. From a logical standpoint, just think about what an AIO is for, to dissipate heat away from your cpu, dispersing it through liquids and the radiator. I have two radiators across from each other in my Corsair 900D. We’ll recap some of the most critical aspects here: Thermal tests were conducted using an Intel Core i7-6700K Skylake CPU and Z170 mITX platform, parts listed below. Any help would be great because I'm planning on getting the nzxt z73 soon and going to attempting a push pull setup with the radiator on the front because that's the only place it would fit. I wasn't surprised, he was pretty much acts like that since he was born, and it's quite the norm. So anyways, I am fully aware that putting my top radiator as intake would blow hot air into my PC which could heat up my other components. After much extensive testing on UTube (Jay's Two Cents & Linus Tech Tips are 2 good channels to watch) It really does not matter. My current setup has a front mounted radiator as an exhaust and one 120mm fan in the back as intake and two 120mm fans on top as intake. Test it yourself and get back to us with your results. Hot air rising on a small scale, with positive airflow will have negligible difference. Good airflow can reduce temps substantially. The site may not work properly if you don't, If you do not update your browser, we suggest you visit, Press J to jump to the feed. The radiator is 240mm and I also have three front fans as intake as well as one exhaust fan in the back. (you do want positive pressure inside your case, but only a little bit, which you will still have with 3 intake and 3 exhaust since 2 of the exhaust will be going through the rad.). various youtubers have tested the temperature difference between mounting a radiator in front with the intake vs on top with the exhaust, and cpu temps are basically within margin of error. Apparently, this asshole scolded me instead and called me a retard for mounting the top radiator fans as intake. The full test methodology is available in the GamersNexus reviewand was used throughout this cooling optimization test. Intake or exhaust for top radiator? Having played around with the fan setup and testing thermals, I get best cooling with 3x intake top (radiator), 3x intake bottom, 3x exhaust side. Side mounted radiator intake (push), Top-mounted radiator exhaust (pull) I've chosen these two mainly for aesthetic reasons so I don't have the fans visible inside the case. ", First of all, in a case where you have airflow and an air cooled GPU, any theories about rising heat are absolutely irrelevant. Top, not only heat is the argument. I always do front intake only, through a dust filter. edit: if you have a blower style GPU and a PSU with the fan oriented upward so it's pulling air from the case, then there would be an argument for doing top intake as well. All questions should be in this format! Heat rises, so its best on the front or side as intake. I had an expensive gaming computer built and I noticed they installed the cpu liquid cooler radiator w/ (2) 120mm fans over top of the (3) 120mm case fans at the front panel. So i will have a 900D, with 3 AF120 performance as intake, a single AF140 quiet as exhaust in the rear. Bitwit did a good video on this here on why placement matters. I have it as an exhaust with 3 intake fans. Short answer is yes. I got best cooling leaving a side panel off, but you know aesthetics and all. Even a water-cooled machine needs the best PC fans to keep the whole rig running cool, but that's not all they're good for. 6600K + 1060. exhaust is better, although your brother still doesn't know what he's talking about. So, if you want optimal overall temps, you should give your radiator fresh air. Or that has to be exhaust as well? Is it actually OK to use radiators as intakes for your machine? The reason for the difference is that the top of my case cannot take a 280mm radiator. Dust collection is one too. Don’t: Have the radiator … Wasn't expecting to get a reward for my Dickcheese PC Build of 2021! If you had an AIO radiator mounted on top of the case, would you: ... As top intake with good rear exhaust not much heated air gets down to GPU, but everything arround CPU like RAM will run hotter because of warmer air from rad. Looks like you're using new Reddit on an old browser. You want the top fans to exhaust the heat out of your case, not blowing heat into the case. The Cooler Master Mastercase H500 is a chunkily styled and highly engineered case with a great range of cooling options. One good mounting position is to place the radiator at the top of the case with the tubes pointing downwards. Generally, it’s best to have as few obstacles as possible between the intake fans on the front of the case and the exhaust fans on the rear and top of the case. How on earth are you thinking that warm air is heating up the CPU if it blows into the case, man? You can always try it both ways and see the difference in temperature and you’ll see that there really isn’t much. Here is my well sketched diagram of my PC: So what do you guys think? pushing more air in from above is just going to cause turbulent airflow especially with your GPU there too. A 120mm liquid cooler was used for the CPU. But if I were to instead use it as an exhaust fan, I would be blowing hot air into my radiator which can increase the temperatures of my CPU. You could have a toaster on top of the PC and it wouldn't matter. When you have devices running at 80C (or ~176 Fahrenheit), it's a good idea to … I checked the air flow using a thin piece of paper and the middle and bottom fan are working as intake as normal because the paper is getting blown away but the paper gets sucked on to the fan when I bring it close to the top fan and I'm doing the paper check from inside the case and not the front of the case. It would then be picked up by the rear radiator. no...you never want radiator to intake fan into the case that just causes hot air to flow into the case and can make other parts perform worse as a resault. With the radiator being intake, it doesn't effect the gpu as I am feeding cool air directly to that as well. But, no matter who you ask, someone is bound to tell you something different. If you have a larger full tower case, three intake fans at the front and one at the rear exhaust would be a good starting point. Silence freaks may mount the radiator to the front of a silence case, while someone who isn't too worried about maximum CPU overclocking but wants the GPU to run a bit cooler can do a radiator top … Can I do front radiator with intake?? Works well. So anyways, I am fully aware that putting my top radiator as intake would blow hot air into my PC which could heat up my other components. It really doesn’t make that much of a difference. The heatsink alone is significantly cooler than the components, and the air coming from the heatsink even more so. Trust. If you have the top radiator as an intake, a lot of the heat picked up from the components you're watercooling is gonna be dissipated by the radiator, and dumped straight back into the case. Just talking CPU here, not other components. hot air rising isn't really what matters here. but another consideration is dust. The air coming through will be slightly warm at most. but... 5 intake fans vs 1 output fan, you sir are a madman lol. Radiators - Can they be used be intake and exhaust. CPU temperatures were predictably lower when the radiator was placed in the path of unwarmed in-flowing air, while GPU temperatures were lower when inflowing air was not warmed by the CPU. Might be a noobish question but I would like to know. So right now I'm on my second PC build and showed my progress build to my brother so I could try to impress him. The GPU (GTX 980 Ti) was using an NVIDIA reference design cooler (… I have mine set up as intake, had it like that for the last 8 years, when I had i7 4770k and now 3700x, never had any issues with cooling. Per the title, I am confused about the proper way to use a radiator in a PC build. Radiator mounted on top of the case with tubes down. The airflow just moves the air around and most GPUs blow hot air all over the place. but yeah they should be exhaust when you already have the 3 intake at the front. Hi I use a H115i on my 9700k at the top of my case. What gives? I was under the impression that liquid cooling bring heat from the component to the radiator, and the cool air needs to flow across the radiator to cool down the radiator, creating hot air. The ram and vrm run just fine as well. In my case (Corsair Carbide 500r) I have exhaust set at the back, and also, where you'd normally have the tempered glass, I have mesh with a large low rpm fan exhausting too. Does this configuration compromise the intake cfm’s? When you do build, try both and see which configuration works best. The Intake-exhaust direction should go front-to-back and bottom-to-top. The top fans pulls down air through the radiator, hot air goes into the case. Was there any difference comparing to before at all? Perhaps my brother may be right. Using radiator as intake on the other hand hardly effects GPU temps in game. 240mm radiator front-mounted, push-intake configuration. If you mount in the top of the case, using the fans as intake or exhaust is likely to make little difference in a CPU only load. Erm no, people do front intake radiator all the time. Press question mark to learn the rest of the keyboard shortcuts, https://www.youtube.com/watch?v=QjYli6itP38, https://www.youtube.com/watch?v=YDCMMf-_ASE. A 240mm Radiator is the most common and lowest cost way to get an effective water cooled set up. You need your top rad fans to exhaust but I’d tell him you’re swapping them to get your desired air pressure rather than admitting he is right. There was only (1) 120mm exhaust fan mounted at the rear panel. I prefer top-mounted for aesthetics, the build with front/intake radiator mount is simply because the case did not support top/exhaust with the mATX mobo, case is a Corsair Air 240.
