7600gt running too hot

I'm currently running a 7600gt and I don't think my power supply can handle it. I read somewhere that if your 12v rail gives a low reading your system is under powered. The GPU is at 54 degrees celcius idle and up to 95 degrees under load. I should note my case does not have a front intake fan, there's a vent but it's very thin (not the diameter of a fan). I still have to take the front of the case off to check out where to put a fan. I'm experiencing freezing during nba 2k11 game intros and at tip-off. My readings from cpuid are as follows:

+5v 5.03v
+12v 4.86v
-12v -9.79v
-5v -7.04v

I think they may be mis-matched because 4.86 is very low. When I ran Furmark the only think that changed was the -5v, which went to -7.10v and then back down when I closed Furmark. Thank you.

    Those readings do not make any sense at all. +12V should always give a reading of above 11V.
  2. I get the same readings from speedfan as well so my sensors must be off or something. Here's a link to my psu/case maybe someone can tell me if a 7600gt can run off the psu.

  4. While our PSU is a POS, the 7600gt is a very low powered card with no external power connector, and this PSU should be ok. Either way, the psu will not be the cause of overheating, most likely you need to blow the dust from the heatsink/fan with compressed air and if that doesnt help re-seat the heatsink with AS5 thermal compound. If you cant do that, the just get a new card, a gt220 is probably equivelant and is dirt cheap.

    I have a 7600gs in a Dell Precision 450 and those are average temps.
    If you dont have freezing during other games or apps then i wouldnt worry
    Try using Everest Home edition for PSU readings.
    Always been reliable for me.
    Good luck
  6. There's a 7600gt XFX OC edition in the comp im using now and idle is 60 c at 33% fan speed. So your temp is probably ok. But HWmonitor is not reading those voltages correct.
