https://www.maketecheasier.com/intake-exhaust-fans-airflow-desktop-pc Basically one of those things where it's just personal preference. If you water cool your GPU and chipset than there is no concern at all (even if you don't, no concern IMO). Followers 0. Build Help. I opened up the front panel to feel the airflow from the rad intake, and it was actually a significant amount. Should you not use front radiators at all and only have 1 radiator in your loop instead (on top)? As for the actual radiator. Wise Guy. It doesn't really matter where the warm air goes, as long as it's not being blown through your radiator. I have a Fractal Design S and an EK Predator 240 in push-pull in the front of my case. for example having 1 or 2 fans as intake in the front of your case, and 1 side intake, should do the trick, and your Radiator as exhaust on top. 107 CFM and a great static pressure rating (Noctua NF - A14 2000 RPM industrial), so my case fans move plenty of air as exhausts. Is 60 degrees C bad in a stress test, though? my three exhausts are my top mounted 360mm rad. if i were to add a 240/280mm front rad I would keep them as intakes even though this would warm the air as it entered the case. A radiator is mounted up front with electric fans blowing the hot air into the car, onto the engine. 2X Fan intake or exhaust top of case? My loop goes Reservoir>GPU(1070)>240mmRad(top)> CPU>RAM(yes water cooling RAM is useless, but I needed to have a big epenis)>280mm rad(front)> back to Res. The ram and vrm run just fine as well. Show only OP | 11 Aug 2019 at 21:47 #1. Heat rises, so its best on the front or side as intake. Mounted on top as exhaust would be better overall. But intake would be more ideal. Have no intention to water cool that. That's my problem because using it on top is the only option for this case. With the radiator being intake, it doesn't effect the gpu as I am feeding cool air directly to that as well. The fans have enough power to overcome the restrictions. Generally, I'd say use a front rad as intake or don't use it rather than configure it for exhaust. I currently have a 240mm radiator mounted at the top of my CM 690 II Advanced. I have 5 filtered intakes and three exhausts not including the PSU which is a separate air path, though its intake is also filtered. Cookies help us deliver our Services. I'm running the vardars though, they seem to be working quite nicely with a fan curve. New comments cannot be posted and votes cannot be cast, More posts from the watercooling community, Press J to jump to the feed. You will get slightly worse cpu temps, but better gpu. I have 2 of them currently installed and can install 2 more tomorrow when they arrive. Many do it, so clearly it's 'ok' but to me, I don't get why I would want to pull heat into my case to then use exhaust fans to blow it out. Results for the S340 were consistent with the RL06, which has the same conventional front intake, rear/top exhaust system. My uncles PC has 2 front intakes and 2 top exhaust and 1 back exhaust. My GPU isn't watercooled. By using our Services or clicking I agree, you agree to our use of cookies. ...fan airflow is basically the result of the pressure differential between intake and exhaust sides of impeller, .. and as such impeller has no idea if radiator is in front or behind it. Have higher pressure static fans on rads and high airflow as normal case fans, or Magnetic Levitation Pro corsair fans as all your fans. Intake v exhaust AIO radiator top mounted. / Cpu Aio liquid cooler located back of case. Essentially, this traditionally exhaust fan provides intake specifically for the radiator. Meshify C: 280 mm front intake or 240mm top exhaust. So two intakes, one exhaust, radiator as either? Printable View. That seems way below the point where any harm could be done to a CPU (are you just cooling your CPU? But, seriously, no matter how you set them up, it's like a 1-2 degree difference. Jonnybmac. My temps under gaming load are in the 40's as well, but stress testing increases that by about 20 degrees. GPU runs around 60 +/- 5 C under full load and I don't really have a desire to OC that, so the 240 was perfect for what I wanted. Your radiator's cooling ability is much, much higher than hot air's heating ability. By TraptPatriot, June 9, 2012 in Overclocking and Cooling. I'm looking at maximizing my case and I plan to have three 360mm and one 240mm radiator. In game I'm averaging 40 degrees C, with about ~60% speed. Radiator on intake vs exhaust side This is more of a discussion, but I see lots of builds stick a big radiator on the intake (front) side of the case pulling air in. https://www.youtube.com/watch?v=UyC3lZ5WFMk Here you go! Unfortunately thats not the results I found. Press question mark to learn the rest of the keyboard shortcuts, https://picload.org/image/rrcglppc/foto09.08.16191808.jpg, https://www.youtube.com/watch?v=UyC3lZ5WFMk. Consider this: this is exactly how a car works. I don't think the restricted airflow is an issue. The front only has room for the 1x200mm fan at the bottom. 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. The Intake-exhaust direction should go front-to-back and bottom-to-top. Only thing is that I would be fighting heat rising. Silverstone is one of the few exceptions to this and they have repeatedly introduced cases which use an AP181 as a top intake. When I first got my H100 I tried it in 4 different configurations. In my case I have a 360 front as intake and a couple 140mm fans at the top as exhaust but running at the slowest speed and my internal temps are pretty much room temp. Top Radiator .. Intake or Exhaust? ... -Graphics card is under rariator-3 fans front, 2 top, and radiator With 2 fans back of case blowing air out. But .. and it's a big 'BUT' .. the exhaust side of a fan has impellers 4-5mm farther away from fan mounting surface (fan housing) then on intake side. I get 73c on the hottest core on a 6700k at 1.37v cooled by a predator 360. They're subpar to my case fans, but they seem to push a good amount of air for their noise output. Yes, but they give you great airflow and pressure(best of both worlds). 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. It sounds like you think they don't though. I had the 360 Predator in the front of the Define S in Push/Pull and it was perfect. I don't actually do water cooling so maybe someone with more experience will answer, but if I'm understanding correctly then you have five fans, four on the radiator and one more. Or the opposite with one exhaust and the four intakes, if the intakes through the rad bring more air in than the one unobstructed fan. Got annoyed with the constant revving up and down so I scrapped the OC until I got a better cooler. Fans are significantly more powerful than convection, so the air is going to go whichever direction it's being pushed in, not up. Because it works. Page 1 of 3 1 2 3 Last. What do you recommend to be the best for my radiator orientation? Side-mounted fans can be intake or exhaust, depending on the setup. Hmm, I did not think of mixing the fans like that. Yeah, 60 C on the CPU only. CPU and GPU temperatures remained exactly the same. Keep in mind the liquid temperature must be kept below about 45C or the lifespan would be greatly reduced. Rear rads look messy and top ones intrude on the motherboard. Top Mounted Radiator, Intake or Exhaust Sign in to follow this . https://youtu.be/xNAMxZgvves. A top fan should never serve as an intake. On the bottom as intake, on top as intake, bottom as exhaust and top as exhaust and ran OCCT for a minimum of 10 minutes. The cpu is getting fresh, cool air. Jump to page: 03-11-2011, 11:05 AM. It negates the most simple physical aspects of hot air and general case airflow. Unless I'm wrong. While that may be true in natural convection once there is airflow in the case the effect of convection is minimal. Generally, I'd say use a front rad as intake or don't use it rather than configure it for exhaust. If you have filtered intakes elsewhere, though, would be fun to try it. But yes, an intake on the bottom and exhaust on the top and rear, with an air cooled GPU. I hope not. Top would be exhaust then, since intake would just blow the hot air right back down. If you have filtered intakes elsewhere, though, would be fun to try it. Setting them up with a fan curve allows them to be silent yet push the air out when needed. Manage Your Cables and Other Obstructions. Heat rising is essentially irrelevant in a PC case with fans. My question is if I'm limiting airflow and/or cooling by going with either of these and … My system hits 60 when I'm playing games hardcore. So I have my radiator mounted forward and rear and top rear as exhaust. Fans on the bottom, … New comments cannot be posted and votes cannot be cast, More posts from the watercooling community, Press J to jump to the feed. Top Mounted Radiator, Intake or Exhaust. using the radiator as intake, will get your GPU and other components in your case to little cool air, since you will be blowing hot air into your case. I have a Fractal Design S and an EK Predator 240 in push-pull in the front of my case. You know why it's done this way? Built a pc in a corsair 100r with a h100i set up as intake in the front and gpu temperatures are quite a bit higher than in a very similar build (same gpu, nearly same cpu) where the cpu cooler only uses one 120mm fan as intake and the gpu gets it's own 120mm intake. So, if you want optimal overall temps, you should give your radiator fresh air. In a stress test, my GPU hits 46 degrees max, Yes, but what about CPU? Top exhaust. I personally like the front radiator for looks. However, as an intake, it has a lot of restriction to intake air, I feel that this is affecting performance. If I flip the orientation of my fans, do you think this would generate better performance? That sounds pretty good. As for the orientation, usually in on the front and bottom, out on top and back. It would then be picked up by the rear radiator. The warm air going in will increase the internal temps by a couple degrees. Ill use a front, a side, top , or any rad there is to dissipate heat. The best method is push and pull. Just try and have natural airflow through your case, push/pull on a RAD sounds like it helps airflow, but as long as you push through the Rad and you bought a decent Rad with good fin spacing, just push won't be much different than the push/pull. Less critical: Side intake. Sometimes even 62. And for all four cases, the direction should not be reversed. There will be a single 92mm exhaust fan on the back of the case. And radiator only fits back of case so can't move it anywhere other location on case. There are 2 Cooler Master 120mm LED fans on top of the rad (I also have 2 Yate Loons lying around - would those be better?). 60c, is that stock clocks? I got about a 2 C difference between intake on the front and intake or exhaust on the back or top … just because of the importance of positive pressure on keeping dust out of the case. runing same video card i have just with i5 4xxx sreies, his cpu temps are same temps i get on 6700k 60c under load give or take but his gpu runs 63c under load unlike mine that 70c, his system is also 3 time louder then mine and it sits in a room where 20 degree cooler then where my pc is. More is rad is better. So i will have a 900D, with 3 AF120 performance as intake, a single AF140 quiet as exhaust in the rear. Hmm, I'm not quite seeing the 7mm rubber shrouds in your set up. Discussion in 'Overclocking & Cooling' started by Jonnybmac, 11 Aug 2019. Bottom 45x360mm intake, front 30x240mm intake, side 30x360mm intake, top 360mm exhaust. Is 60 degrees C bad in a stress test, though? I will say, though, that it isn't as pretty as other builds. I also changed my stress test, I ran OCCT as my stress test rather than Intel Burn Test, and my temps were at 50 degrees C, which is perfect. Is it still worth it when all that warm air goes back into the pc? I idle around 23-25 degrees and on max load I sit at 42-43 degrees. expensive? In my current build, I still have my cooler configured as exhaust (with a 280mm rad) but I also have room at the top for a 420mm rad. I have a top mounted radiator, XSPC RX360, and will have push pull fans. Using radiator as intake on the other hand hardly effects GPU temps in game. Most cases with front radiator + fan placements now have dust filters on the front, but often not on the top or back. I'm pretty sure they are stock clocks I had 1.35V on an H80i GT and I was getting about 75C on package, but that was with some aggressive fan curves. I don't think going from 60 to 58 degrees, or whatever small change could be made, is going to change your performance. 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. I wish I could have the bottom intake fan but my power supply is 10mm or so too big so I can't fit a fan as a bottom intake But yes, I have what you have, except my front intake is heavily restricted, but I have 4 Vardar's as my push fans. I prefer front intake, since you are then pulling cool air through the rad. The most cited reason for this is because hot air rises so it makes sense to use it as an exhaust. What do you recommend to be the best for my radiator orientation? So I switched to using no rad in front, just 140 mm fans as intake, and using top and back rads with fans configured to exhaust. I am getting 60 degrees C in stress tests. My case only has 240 space front, and 360 top, There was a video about location of radiators. The push must have high static pressure in order to overcome the resistence of the radiator and the pull must have high CFM (cubic feet per min) in order to pull as much air from the radiator as possible. More critical: Front intake. Back exhaust. 60°C on the CPU? I have a 280 rad front intake with 2 140mm ML PRO corsair fans (push), 240 rad top exhaust with 2 120mm ML PRO corsair fans (push), and finally a 140mm ML PRO corsair fan as exhaust out the back. Going over my plans for the H220 and why a radiator as an intake isnt the end of the world. ), so how could you be getting more performance? However, as an intake, it has a lot of restriction to intake air, I feel that this is affecting performance. Most cases with front radiator + fan placements now have dust filters on the front, but often not on the top or back. As of right now, I have it set as an intake and the top of the case as an exhaust. Alright, so I installed the 2 extra case fans... annnnnd it made absolutely no difference. Make sure you're intaking from front and bottom, if your case doesn't allow bottom fans like mine, no big deal, but I recommend always exhausting out of the back and top. TheFlyingDutchMan. Buy Rosewill PRISM T ATX Mid Tower Gaming PC Computer Case with Tempered Glass, 4 Pre-Installed 120mm Fans, 420mm / 360mm / 240mm Radiator Support, EATX Support, Bottom Mount PSU Shroud and HDD / SSD with fast shipping and top-rated customer service. Postmodum. I just have 4 high static pressure. 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. You'd think with "a couple degrees" difference between rad intake and exhaust, it wouldn't much matter having a radiator placed coincident with exhaust. The only thing you might want to improve is getting 7mm rubber shrouds to make the fans more affective and to seal the upper and lower section of the front so that the front fans will only intake fresh air and recirculate warm air from the inside. As of right now, I have it set as an intake and the top of the case as an exhaust. Top Radiator .. Intake or Exhaust? 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. My question is, is it better to have them set for exhaust or intake? I was watching some youtubers put the radiator in front and have it serve as an intake instead of exhaust. I have an HAF 932 Advanced case, 230mm intake on front and side, and 140mm exhaust on rear. Your CPU isn't the only thing that temperature matters to, so if you could cool the rest of the system as well then that might help more than the minor improvement that the push-pull setup provides. Here is a pic of the setup: https://picload.org/image/rrcglppc/foto09.08.16191808.jpg. I did have a top mounted position, but I switch cases because I couldn't stand the inverted motherboard. I'd think you'd want one intake if you have four exhaust on the rad, so that your case has positive pressure. Press question mark to learn the rest of the keyboard shortcuts. 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. Also, it just looks better. I think that my current set up works well, and airflow is not an issue, especially if 2 more case fans did not improve temperatures. Looks great by the way! In my Fractal Design Nano S build, recently, I started with a front rad as intake, but ultimately felt I couldn't get enough airflow through it at low enough noise levels for me (I want things very quiet) due to the front panel restricting airflow. Top Radiator .. Intake or Exhaust? GPU is running on air. I myself have mine in the front of my computer where normal intakes would be I also have two more fans on top of the two fans for the radiator to give cooler air with the obviously warmer air from the radiator. Joined: 17 Dec 2009 Posts: 1,881. Long story short it depends how your graphic card is. Show 100 post(s) from this thread on one page. Should front radiators be put with intake fans?
