i just recently dumped a new packet of thermal paste and cleaned out the heatsink and fan, so they're running optimally. that seemed to keep the temperature down a bit. i have the side of the case open and the back of the case has empty holes where the pci slots are, so i have a big box fan blowing air into it and the air is certainly circulating. please note that it is very cool in my house, as the air condtioning is on. i definitely don't think it has to do with air circulation as much as cpu corruption.

i have a shuttle av41p, by the way.
