my desktop keeps overheating, it is about three years old this coming December. i have expelled all dust out of the case, that helped for like .5 degrees F ... anyway Ive installed speed fan, it says my fan is at 4588 RPMs is that good? any help would be great. also this thing is custom built from a local computer store so its no brand name PC, and that's probably not the problem because its always been below like 80 degrees F for the past years any help? EDIT: just some more info, so i can maybey narrow down alot of things that could be wrong. Speed fan is reading CPU: 105c internal temp:62c remote temp:62c local:52c remote:56c HD0:51c core:60c ambient:52c all of these listed have a picture of a flame next to them, im guessing that thats way too hot in that area.
