So what's the message here? Don't take off your HSF while you're computer is running? Gee, thanks for the heads up, because I was planning on doing that just right now...
Got an AMD 64 3500+ and haven't had any issues with it... it just used to shutdown my computer when I installed a whole bunch of stuff in my case without extra cooling and an extra exhaust fan took care of that.
I think Pentiums are the ones with problems now... those Prescotts make a hell of a lot of heat.
P.S. Greatest music ever since Bach.
