Woo, I fixed my CPU fan! For the longest time, it hasn't been running. Every time I did something CPU intensive for a sustained period of time, the CPU would overheat and restart the machine. Half a bottle of WD-40 put an end to that! I was so satisfied with my new fan that I dug out the motherboard manual and tried my hand at some overclocking (I'm still running my trusty 233-MMX). It was to no avail, though. When I bought this box, it was clocked as high as it would go.
