Yes, but they give you great airflow and pressure(best of both worlds). The fans have enough power to overcome the restrictions.

Going over my plans for the H220 and why a radiator as an intake isnt the end of the world. Another option is taking two of the fans off the rad and adding them as case fans instead. ...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. Silverstone is one of the few exceptions to this and they have repeatedly introduced cases which use an AP181 as a top intake. Hmm, I did not think of mixing the fans like that.

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.

Printable View. My question is if I'm limiting airflow and/or cooling by going with either of these and … Your radiator's cooling ability is much, much higher than hot air's heating ability. Show only OP | 11 Aug 2019 at 21:47 #1. So, if you want optimal overall temps, you should give your radiator fresh air. Top Mounted Radiator, Intake or Exhaust. 60c, is that stock clocks? Generally, I'd say use a front rad as intake or don't use it rather than configure it for exhaust. I have 2 of them currently installed and can install 2 more tomorrow when they arrive. / Cpu Aio liquid cooler located back of case. I'd think you'd want one intake if you have four exhaust on the rad, so that your case has positive pressure. 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. Back exhaust. More is rad is better.

Meshify C: 280 mm front intake or 240mm top exhaust. Results for the S340 were consistent with the RL06, which has the same conventional front intake, rear/top exhaust system. 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. Postmodum. 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. It negates the most simple physical aspects of hot air and general case airflow. If you have filtered intakes elsewhere, though, would be fun to try it. I have an HAF 932 Advanced case, 230mm intake on front and side, and 140mm exhaust on rear. The ram and vrm run just fine as well. Is 60 degrees C bad in a stress test, though? 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. 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. I get 73c on the hottest core on a 6700k at 1.37v cooled by a predator 360. Because it works. 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. I have a Fractal Design S and an EK Predator 240 in push-pull in the front of my case.
