If it were lots more people, including me, would be having issues. I think the problem here lies with the externals (fans, case, room temp. etc.). I do agree with FreeBSD not halting a processor. I've seen data and experienced it myself that when temps are regulated properly.. things in general last longer. This phenomina is similar to bending a pieve of metal over and over or turning on and off a light bulb. The kernel isn't the issue. It's the box itself. --- Jason jason@jason-n3xt.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
