I can't seem to fix the cooling in my case no matter what I try, so I need some input from more experienced people. Basically all the hot air (which is mostly generated by the graphic btw) card goes straight into the PSU for some reason I can't seem to understand. Attached is current picture of my PC. The fans, if it's of any importance, are: CPU: Noctua P12 graphic card: Noctua S12 (mounted onto Accelero S1 Plus) top: Corsair AF140 intake: (surprisingly silent) Lian Li fan shipped with the case Original state of the case was no intake/outtake fans except for the PSU. I tried several things so far: First I installed a fan as rear outtake (some 1100 RPM). No change whatsoever. Second, I bought the Corsair fan. There was some very slight improvement: the PSU fan would stop at around 1400 RPM instead of going all the way to 1700-1750 (not quite sure what the real max is) and the VRMs on the graphic card would not go over 97°C (the record was 105 before), and the GPU was a little bit cooler as well. Ironically, there was hardly any difference between running the fan at 700 RPM and its max of 1100 (except for annoying noise in the latter case) Third, I experimented with adding rear fan (didn't use it the first time I tried the Corsair out). Zero difference. Fourth, I added front intake fan. Absolutely zero difference. Later on I also removed the HDD cage which was sitting in front of the intake fan, and moved a disk to 5.25" bay and into one of those silencing enclosures. Needless to say, no change in airflow. The main problem is obviously the airflow, which just completely ignores the huge Corsair fan that's supposed to do most of the work, and instead tries to rape my poor PSU, which in return punishes me with the sounds of 1400+ RPM, which is seriously unpleasant. What baffles me is the absolute ineffectiveness of the rear fan, because all the hot air surely should pass along it, since it's somehow being directed to the PSU, which sits in the same line. Give me some ideas please, I am out of mine.
