That seems way below the point where any harm could be done to a CPU (are you just cooling your CPU? So i will have a 900D, with 3 AF120 performance as intake, a single AF140 quiet as exhaust in the rear. Basically one of those things where it's just personal preference. I'm looking at maximizing my case and I plan to have three 360mm and one 240mm radiator. 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. Top Radiator .. Intake or Exhaust? More is rad is better. 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. More critical: Front intake. In game I'm averaging 40 degrees C, with about ~60% speed. You know why it's done this way? The cpu is getting fresh, cool air. So I have my radiator mounted forward and rear and top rear as exhaust. Have no intention to water cool that. Less critical: Side intake. Ill use a front, a side, top , or any rad there is to dissipate heat. expensive? Rear rads look messy and top ones intrude on the 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. GPU is running on air. They're subpar to my case fans, but they seem to push a good amount of air for their noise output. My uncles PC has 2 front intakes and 2 top exhaust and 1 back exhaust. Show 100 post(s) from this thread on one page. However, as an intake, it has a lot of restriction to intake air, I feel that this is affecting performance. 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. Bottom 45x360mm intake, front 30x240mm intake, side 30x360mm intake, top 360mm exhaust. Consider this: this is exactly how a car works. I hope not. Alright, so I installed the 2 extra case fans... annnnnd it made absolutely no difference. When I first got my H100 I tried it in 4 different configurations. 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. There will be a single 92mm exhaust fan on the back of the case. Joined: 17 Dec 2009 Posts: 1,881. Silverstone is one of the few exceptions to this and they have repeatedly introduced cases which use an AP181 as a top intake. It negates the most simple physical aspects of hot air and general case airflow. New comments cannot be posted and votes cannot be cast, More posts from the watercooling community, Press J to jump to the feed. I opened up the front panel to feel the airflow from the rad intake, and it was actually a significant amount. Sometimes even 62. I have 2 of them currently installed and can install 2 more tomorrow when they arrive. Hmm, I did not think of mixing the fans like that. 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. Only thing is that I would be fighting heat rising. And for all four cases, the direction should not be reversed. Followers 0. My question is if I'm limiting airflow and/or cooling by going with either of these and … my three exhausts are my top mounted 360mm rad. 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. 60c, is that stock clocks? Unless I'm wrong. 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. 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. Postmodum. I have an HAF 932 Advanced case, 230mm intake on front and side, and 140mm exhaust on rear. 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. 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. 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. As for the actual radiator. Fans are significantly more powerful than convection, so the air is going to go whichever direction it's being pushed in, not up. Show only OP | 11 Aug 2019 at 21:47 #1. 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? 2X Fan intake or exhaust top of case? Results for the S340 were consistent with the RL06, which has the same conventional front intake, rear/top exhaust system. Have higher pressure static fans on rads and high airflow as normal case fans, or Magnetic Levitation Pro corsair fans as all your fans. 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. Heat rises, so its best on the front or side as intake. I get 73c on the hottest core on a 6700k at 1.37v cooled by a predator 360. Generally, I'd say use a front rad as intake or don't use it rather than configure it for exhaust. 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. Is 60 degrees C bad in a stress test, though? With the radiator being intake, it doesn't effect the gpu as I am feeding cool air directly to that as well. 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. https://www.youtube.com/watch?v=UyC3lZ5WFMk Here you go! Top Mounted Radiator, Intake or Exhaust Sign in to follow this . Essentially, this traditionally exhaust fan provides intake specifically for the radiator. I did have a top mounted position, but I switch cases because I couldn't stand the inverted motherboard. 60°C on the CPU? Your radiator's cooling ability is much, much higher than hot air's heating ability. 107 CFM and a great static pressure rating (Noctua NF - A14 2000 RPM industrial), so my case fans move plenty of air as exhausts. Manage Your Cables and Other Obstructions. 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. In a stress test, my GPU hits 46 degrees max, Yes, but what about CPU? I'm running the vardars though, they seem to be working quite nicely with a fan curve. My system hits 60 when I'm playing games hardcore. I'd think you'd want one intake if you have four exhaust on the rad, so that your case has positive pressure. The ram and vrm run just fine as well. ... -Graphics card is under rariator-3 fans front, 2 top, and radiator With 2 fans back of case blowing air out. Yeah, 60 C on the CPU only. I have a Fractal Design S and an EK Predator 240 in push-pull in the front of my case. ), so how could you be getting more performance? 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. Keep in mind the liquid temperature must be kept below about 45C or the lifespan would be greatly reduced. That's my problem because using it on top is the only option for this case. Looks great by the way! I had the 360 Predator in the front of the Define S in Push/Pull and it was perfect. If you have filtered intakes elsewhere, though, would be fun to try it. ...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. The most cited reason for this is because hot air rises so it makes sense to use it as an exhaust. I will say, though, that it isn't as pretty as other builds. 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. I have 5 filtered intakes and three exhausts not including the PSU which is a separate air path, though its intake is also filtered. Press question mark to learn the rest of the keyboard shortcuts. That sounds pretty good. 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. My case only has 240 space front, and 360 top, There was a video about location of radiators. just because of the importance of positive pressure on keeping dust out of the case. https://www.maketecheasier.com/intake-exhaust-fans-airflow-desktop-pc Because it works. Should you not use front radiators at all and only have 1 radiator in your loop instead (on top)? My temps under gaming load are in the 40's as well, but stress testing increases that by about 20 degrees. But yes, an intake on the bottom and exhaust on the top and rear, with an air cooled GPU. 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 personally like the front radiator for looks. Is it still worth it when all that warm air goes back into the pc? Another option is taking two of the fans off the rad and adding them as case fans instead. Side-mounted fans can be intake or exhaust, depending on the setup. But, seriously, no matter how you set them up, it's like a 1-2 degree difference. A radiator is mounted up front with electric fans blowing the hot air into the car, onto the engine. Top exhaust. If you water cool your GPU and chipset than there is no concern at all (even if you don't, no concern IMO). 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 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. Build Help. 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. 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?). I don't think the restricted airflow is an issue. 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.
