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. 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?). A radiator is mounted up front with electric fans blowing the hot air into the car, onto the engine. 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. Back exhaust. 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. Have higher pressure static fans on rads and high airflow as normal case fans, or Magnetic Levitation Pro corsair fans as all your fans. I had the 360 Predator in the front of the Define S in Push/Pull and it was perfect. You know why it's done this way? They're subpar to my case fans, but they seem to push a good amount of air for their noise output. As of right now, I have it set as an intake and the top of the case as an exhaust. Jump to page: 03-11-2011, 11:05 AM. It sounds like you think they don't though. That's my problem because using it on top is the only option for this case. It doesn't really matter where the warm air goes, as long as it's not being blown through your radiator. Followers 0. 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. It negates the most simple physical aspects of hot air and general case airflow. 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. 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. My GPU isn't watercooled. 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. 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. In game I'm averaging 40 degrees C, with about ~60% speed. When I first got my H100 I tried it in 4 different configurations. Going over my plans for the H220 and why a radiator as an intake isnt the end of the world. GPU is running on air. By using our Services or clicking I agree, you agree to our use of cookies. Is it still worth it when all that warm air goes back into the pc? 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. / Cpu Aio liquid cooler located back of case. Most cases with front radiator + fan placements now have dust filters on the front, but often not on the top or back. 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. I personally like the front radiator for looks. Hmm, I did not think of mixing the fans like that. Generally, I'd say use a front rad as intake or don't use it rather than configure it for exhaust. My system hits 60 when I'm playing games hardcore. ... -Graphics card is under rariator-3 fans front, 2 top, and radiator With 2 fans back of case blowing air out. 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. I have an HAF 932 Advanced case, 230mm intake on front and side, and 140mm exhaust on rear. Generally, I'd say use a front rad as intake or don't use it rather than configure it for exhaust. 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. Intake v exhaust AIO radiator top mounted. More is rad is better. 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. Yes, but they give you great airflow and pressure(best of both worlds). Top Radiator .. Intake or Exhaust? Because it works. By TraptPatriot, June 9, 2012 in Overclocking and Cooling. 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. Unless I'm wrong. Fans are significantly more powerful than convection, so the air is going to go whichever direction it's being pushed in, not up. So, if you want optimal overall temps, you should give your radiator fresh air. Cookies help us deliver our Services. As for the actual radiator. 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. The fans have enough power to overcome the restrictions. Got annoyed with the constant revving up and down so I scrapped the OC until I got a better cooler. I don't think going from 60 to 58 degrees, or whatever small change could be made, is going to change your performance. expensive? I got about a 2 C difference between intake on the front and intake or exhaust on the back or top … However, as an intake, it has a lot of restriction to intake air, I feel that this is affecting performance. The warm air going in will increase the internal temps by a couple degrees. What do you recommend to be the best for my radiator orientation? That sounds pretty good. Long story short it depends how your graphic card is. 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. 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. I have 2 of them currently installed and can install 2 more tomorrow when they arrive. 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. Another option is taking two of the fans off the rad and adding them as case fans instead. Bottom 45x360mm intake, front 30x240mm intake, side 30x360mm intake, top 360mm exhaust. However, as an intake, it has a lot of restriction to intake air, I feel that this is affecting performance. I did have a top mounted position, but I switch cases because I couldn't stand the inverted motherboard. 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. Show only OP | 11 Aug 2019 at 21:47 #1. The Intake-exhaust direction should go front-to-back and bottom-to-top. Postmodum. The ram and vrm run just fine as well. Printable View. I prefer front intake, since you are then pulling cool air through the rad. Here is a pic of the setup: https://picload.org/image/rrcglppc/foto09.08.16191808.jpg. I idle around 23-25 degrees and on max load I sit at 42-43 degrees. 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. 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. Have no intention to water cool that. I don't think the restricted airflow is an issue. In a stress test, my GPU hits 46 degrees max, Yes, but what about CPU? And for all four cases, the direction should not be reversed. Discussion in 'Overclocking & Cooling' started by Jonnybmac, 11 Aug 2019. The cpu is getting fresh, cool air. 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. 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. Heat rising is essentially irrelevant in a PC case with fans. Build Help. Top Radiator .. Intake or Exhaust? Rear rads look messy and top ones intrude on the motherboard. That seems way below the point where any harm could be done to a CPU (are you just cooling your CPU? Top Mounted Radiator, Intake or Exhaust Sign in to follow this . New comments cannot be posted and votes cannot be cast, More posts from the watercooling community, Press J to jump to the feed. Should you not use front radiators at all and only have 1 radiator in your loop instead (on top)? https://youtu.be/xNAMxZgvves. 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. 60c, is that stock clocks? Sometimes even 62. Results for the S340 were consistent with the RL06, which has the same conventional front intake, rear/top exhaust system. Show 100 post(s) from this thread on one page. I get 73c on the hottest core on a 6700k at 1.37v cooled by a predator 360. If I flip the orientation of my fans, do you think this would generate better performance? 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. 2X Fan intake or exhaust top of case? I have a top mounted radiator, XSPC RX360, and will have push pull fans. 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. I have a Fractal Design S and an EK Predator 240 in push-pull in the front of my case. Alright, so I installed the 2 extra case fans... annnnnd it made absolutely no difference. Looks great by the way! 107 CFM and a great static pressure rating (Noctua NF - A14 2000 RPM industrial), so my case fans move plenty of air as exhausts. Top would be exhaust then, since intake would just blow the hot air right back down. Manage Your Cables and Other Obstructions. Yeah, 60 C on the CPU only. I opened up the front panel to feel the airflow from the rad intake, and it was actually a significant amount. Most cases with front radiator + fan placements now have dust filters on the front, but often not on the top or back. There will be a single 92mm exhaust fan on the back of the case. While that may be true in natural convection once there is airflow in the case the effect of convection is minimal. And radiator only fits back of case so can't move it anywhere other location on case. Using radiator as intake on the other hand hardly effects GPU temps in game. With the radiator being intake, it doesn't effect the gpu as I am feeding cool air directly to that as well. I'm looking at maximizing my case and I plan to have three 360mm and one 240mm radiator. Is 60 degrees C bad in a stress test, though? 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. https://www.maketecheasier.com/intake-exhaust-fans-airflow-desktop-pc I'm running the vardars though, they seem to be working quite nicely with a fan curve. What do you recommend to be the best for my radiator orientation? I have 5 filtered intakes and three exhausts not including the PSU which is a separate air path, though its intake is also filtered. My question is if I'm limiting airflow and/or cooling by going with either of these and … Top Radiator .. Intake or Exhaust? Keep in mind the liquid temperature must be kept below about 45C or the lifespan would be greatly reduced. Silverstone is one of the few exceptions to this and they have repeatedly introduced cases which use an AP181 as a top intake. My question is, is it better to have them set for exhaust or intake? Only thing is that I would be fighting heat rising. Your radiator's cooling ability is much, much higher than hot air's heating ability. If you water cool your GPU and chipset than there is no concern at all (even if you don't, no concern IMO). https://www.youtube.com/watch?v=UyC3lZ5WFMk Here you go! TheFlyingDutchMan. But intake would be more ideal. It would then be picked up by the rear radiator. 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. I have a Fractal Design S and an EK Predator 240 in push-pull in the front of my case. A top fan should never serve as an intake. Heat rises, so its best on the front or side as intake. Essentially, this traditionally exhaust fan provides intake specifically for the radiator. Press question mark to learn the rest of the keyboard shortcuts. The best method is push and pull. I was watching some youtubers put the radiator in front and have it serve as an intake instead of exhaust. So I have my radiator mounted forward and rear and top rear as exhaust. Mounted on top as exhaust would be better overall. Jonnybmac. I will say, though, that it isn't as pretty as other builds. The front only has room for the 1x200mm fan at the bottom. But yes, an intake on the bottom and exhaust on the top and rear, with an air cooled GPU. 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. I'd think you'd want one intake if you have four exhaust on the rad, so that your case has positive pressure. Is 60 degrees C bad in a stress test, though? Ill use a front, a side, top , or any rad there is to dissipate heat. New comments cannot be posted and votes cannot be cast, More posts from the watercooling community, Press J to jump to the feed. I hope not. my three exhausts are my top mounted 360mm rad. CPU and GPU temperatures remained exactly the same. I currently have a 240mm radiator mounted at the top of my CM 690 II Advanced. I am getting 60 degrees C in stress tests. So two intakes, one exhaust, radiator as either? 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. Hmm, I'm not quite seeing the 7mm rubber shrouds in your set up. 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. 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. Basically one of those things where it's just personal preference. If you have filtered intakes elsewhere, though, would be fun to try it. Meshify C: 280 mm front intake or 240mm top exhaust. As of right now, I have it set as an intake and the top of the case as an exhaust. Should front radiators be put with intake fans? Wise Guy. Top Mounted Radiator, Intake or Exhaust. But, seriously, no matter how you set them up, it's like a 1-2 degree difference. As for the orientation, usually in on the front and bottom, out on top and back. Joined: 17 Dec 2009 Posts: 1,881. Fans on the bottom, … 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. My uncles PC has 2 front intakes and 2 top exhaust and 1 back exhaust. Less critical: Side intake. Also, it just looks better. 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. Unfortunately thats not the results I found. I just have 4 high static pressure. 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. My temps under gaming load are in the 40's as well, but stress testing increases that by about 20 degrees. Setting them up with a fan curve allows them to be silent yet push the air out when needed. So i will have a 900D, with 3 AF120 performance as intake, a single AF140 quiet as exhaust in the rear. 60°C on the CPU? Top exhaust. ...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. ), so how could you be getting more performance? Consider this: this is exactly how a car works. 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. Side-mounted fans can be intake or exhaust, depending on the setup. You will get slightly worse cpu temps, but better gpu. 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. The most cited reason for this is because hot air rises so it makes sense to use it as an exhaust. Page 1 of 3 1 2 3 Last. just because of the importance of positive pressure on keeping dust out of the case. More critical: Front intake. My case only has 240 space front, and 360 top, There was a video about location of radiators. If you have filtered intakes elsewhere, though, would be fun to try it.
