Hi So, I made the choice of checking my temps on this computer, since the case was very hot in the back and I suspected something was wrong. First of all, my "old but still good" build: CPU: Intel Pentium D 945 @ 3.40 Ghz ---- Cooling device: Artic Cooler Freezer 11 Rev. 2 GPU: XFX Geforce 6800GS 256MB AGP8X ---- Cooling device: Zalman VF800-Cu HDD: Seagate Barracuda 7200.7 120GB IDE + Hitachi Travelstar 80GB USB Fans: Processor (intake via CAG 1.1), Rear Outtake + PSU Outtake + Front Intake + Some holes in the case (already there) The temps are as follows: (colors indicate state of attention) Ambience: 42ºC <--> 51ºC (inside the case) CPU: 52ºC <--> 65ºC GPU: 62ºC <--> 96ºC GPU Ambience: 50ºC <--> 62ºC HDD0: 36ºC <--> 44ºC (directly above the intake fan) HDD1: 29ºC <--> 32ºC (USB case away from this nonsense) (Room temperature is around 23-26ºC because of summer) So the temps that worry me are the colored ones, especially that bold italic underlined red one which is really stressful. Well, I know the GPU is hot, what I wonder is 1) how to make it go cooler and about all the temps: 2) is the room temperature a factor to this? 3) is the CPU hot for what it should? I hear P4's are very hot, and since this is a Dual Core P4 4) the HDD1 used to be inside the case (temps 40ºC <--> 51ºC), but kept clicking and having low performance. It stopped the moment I took it from there. While this is nowhere near to happen with HDD0, is the temperature affecting possible performance?
