So who else's systems have overheated today? 
My P4 rig is running 41c CPU and 40c case temp. My dual P3 500MHz file server overheated an hour ago at 70c. Some alarm went off that I hadn't heard from it before and so after investigating I shut it down
Shockingly, my brother's Prescott P4 has barely broken a sweat at 37c. Although its CPU fan is audibly louder today.
