There was no shutdown, but there was a point where I moved my case and the HS actually came out of contact with the processor. I put it back in a few seconds and shutdown, and the system was idle, but i'm still kinda worried.
The thing was really hard to get on correctly, i had to remove the motherboard from my case and really power in those stupid plastic tacks.
How should I go about making sure i'm running normally in prime95? Will the results at the end of a stress test tell me the speed I was running at and all?
