Bad case thermals in Power Supplies Posted April 21, 2019 44 minutes ago, Mattias Edeslatt said: Of course you are getting 10 C lower temps with that setup feeding "cold" fresh air directly to the CPU from the top instead of it pulling air from the top of your GPU that is pre-heated (even with "fresh" air from the front fan). I set it that way mostly because the noctua was doing an awful high pitched noise. Turns out that when the fans are in pull they will do that noise, in push they wont. If I tried to do push with the exhaust to the back of the case I would run into clearance issues, as the fan on top of the ram would not let me close the case. I could have done intake from the back of the case, but I settled for the intake on the top, so that the air from the CPU cools at least the backplate of the gpu.
