Alright, I've looked everywhere. For some reason, my computer says the CPU temperature is at a whopping 117 degrees celcius (and thats at BIOS, without running ANYTHING). I bought a new CPU fan and reapplied thermal grease to the cpu, but the temperature has only gone UP. What the hell is happening? If i let it rest for a long time, i can play for up to an hour, but usually it shuts down within 60 seconds of start up. Any suggestions? Could it be a sensor error? (I dont see how my computer could be running that hot for that long without the processor melting...) (CPU fan is running at about 2600rpm, and the overheating is the only problem) Help is IMMENSELY appreciated. This computer has been having one problem after another since i purchased it from cyberpowersystem. Don't ever buy a computer from them.

that processor is a heat beast. i remember, i owned one. but i dont think it should be getting that hot. hows the case ventilation? are you sure u have not put on too much thermal grease?(this actually makes heat issues worse) also is there any overclocking/overvolting done to the cpu?

"I dont see how my computer could be running that hot for that long without the processor melting" Your CPU has built-in thermal protection circuitry. Once it reaches the "trigger temp", it throttles back...if the temp continues to rise, it will shutdown to protect itself from overheating to death. 112C (if it's an accurate reading) is well above the trigger temp. Assuming the temp reading is accurate, the problem can really only be caused by one thing...the HSF wasn't properly installed. You should have used a small dab of paste about the size of a grain of rice & since you have a dual core CPU, the paste should have been applied in a thin line down the center of the cores. If you apply the line of paste 90 degrees off, you won't get the proper coverage when the HSF is locked down & the CPU will overheat. See the pic on page 4 of the instructions: http://www.arcticsilver.com/pdf/app...

The thing is, i would have to lower my computer temperature a massive amount to get it in the safe range. imma go downstairs and reapply my thermal grease and reattach the heatsink, and keep my fingers crossed.

How long have you had this system & how long has it had the temp problem? Throttling usually kicks in at about 75C +/- so your system *should* have been running extremely slow. As zcubed put it, your CPU is a "heat beast" therefore it's critical to have the HSF & paste installed correctly to tame the best...lol. http://processorfinder.intel.com/de... Just out of curiousity, why did you get the inferior Pentium D when the the Core 2 Duo has been available for about 2 yrs now?

I have a very similar problem with a Conroe Celeron @ 1.6GHz and tried everything I can think of just like you have, lets hope that if you get help that fixes your issue it'll help me out to!
