My desktop machine began to overheat I guess two weeks ago now. I found out there was a problem because my motherboard began to warn me with its heat alarm. I have water cooloing on my CPU. To confirm that it was an overheating problem I downloaded SpeedFan. I found that two of the sensors were constantly overheated, though since the sensors are named Temp1, Temp2, etc. I have been have problems even figuring out what is over heating. I did run some tests, when I am sitting in Windows the two temps that I mentioned are overheated, but when I enter a game two other temps sky rocket, the temps that are already overly hot creep up alittle. So, the really mystery is what is over heating.
