Okay here's "sensors" output at start of mprime test. The mprime -t output. Then "sensors" output at mprime failure.

I made a simple bash script to fire off all three commands so the sensor outputs are immediately before and after mprime test.

During the test, temps went up to 48.5 C and held steady. Now after test temp is back down to 34 C.

I'm not clear what the "ALARM" lines are all about?

I really wasn't concerned about the cpu cooler so much. It's a Intel cooler from my 3 ghz P4 Prescott. I don't overclock or game. I figured Intel should be able to keep their own stuff cool under normal conditions. Let's hope?

About the warranty? LOL! This is a homebuilt box made from salvaged parts from other (mine) homebuilt box parts. I believe the cpu is a 2 or 3 years old by now.

I'd love to throw the 3 ghz. on this board, but for some reason it won't even post. I don't have another motherboard that will accept either processor. Well I have one, but it can't be trusted. It has some visible physical damage from my 4 year old standing in my open computer that was left unattended for a moment. No.... this cpu wasn't mounted in it.
