I built my current system in summer of 2001 (Athlon XP 1600+ and Epox board). I used to keep track of CPU temps but didn't after awhile. Lately I've noticed that it has been running hotter and it alarmed out on my one time playing America's Army. I installed Mobo monitor and let it run all day. My high was 141F and average was 137F and my system temp was around 90F (and my room is 70F). I decided to open the case up and check things out. Examined the cpu heatsink/fan and was just packed with dust. I decided to pull the heatsink/fan off the CPU to make sure that was fine. The CPU looked fine but the the heatsink goup stuff was completely hard. I was looking at the mobo and noticed all the little capacitor things around the area had corrosion looking stuff on the top of them (like the stuff on top of really old batteries). These capacitors are all over the board but only the ones near the CPU have this crap on them. Anyone know what this is all about? I'm gonna get a can of compressed air so I can clean the thing out well but this corrosion kind of worries me. Also think I will scrape off the heatsink goup and put fresh stuff on.
