I just traded towers with my Slot A.(the tower from the Slot A post is now the home of my 1.33 Bird) Now My A7A266 with a 1.33@1.50 Tbird @ 1.750v is showing 131ºF cpu/86ºF system. The room temp is 75ºF. I , NascarFool, being of sane mind and a damned good HVAC tech, am the owner of several electronic devices.

(just had to toss that in there) I have a Raytek Infrared thermometer and when I check the temp at the bottom of the HFS, it shows 93ºF. Now I now that temp is not the same as the core but 38ºF differance ? The heatsink is not hot at all, in fact it's not warm either. It feels cool to the touch. I use MBM5.09 for temp monitoring. The above mentioned temps are with Folding@Home running.
