I have an ASRock K7S41 mobo and I've FINALLY upgraded my ancient AMD Duron 700 to a "not-as-poor" AMD XP 2000. I bought this Akasa cooling unit on recommendation and went to work. Installation went fine, and I opted for manual speed control instead of the temperature probe, because we all know an extra dial on a PC is cool.

The Problem IS:

After about 2 hours the fan speed drops from 3000rpm (the max speed) to about 1000rpm and the system overheats and shuts down. I've re-opened the case and checked all my connections, but nothing is wrong there.
The only thing I can think of is that my case and PSU are VERY old, the PSU is only 250w. (my system was cannibalised from many old parts I found laying around)
Would this mean the power to the fan was fluctating and causing these problems?

I haven't been using the system for anything CPU intensive (just for video, music, general media and internet use) so I don't know how the CPU is overheating!

HELP ME! What's wrong!?
