I have an amd 2000+ asus a7s333 mobo .. 3 case fans (2 intake 1 exaust) 1 cpu with heatsink and fan , all of them are working properly yesturday i was working on a webpage and then my computer shutoff automaticly, cpu was @ 170F (i noticed that the power supply was exausting alot of heat) i opened the computer and clean every parts with a F#$% Q-tip (inside the power supply, fans etc) I left the power supply on all night (using the green and grey wire.the power supply was not connected to anything) this morning the power supply was working properly and did not produce any heat. after cleaning the cpu and heatsink I added thermal grease and plugged everything back into the computer. push the on button..after 60 seconds my cpu was already @ 55C i checked the cpu fan (air was cold) checked the power supply fan (air was hot) theres a fan in the power supply that pushes the air into my computer directly on the cpu. could the sensors read the air from the power supply and give me false reading? is it normal for a powersupply to produce that much heat? my computer is @ least 4-5 years old.. what should I do?! please help !
