>I read something in a forum, that said the CPU temperature can go to >100 C., in a few seconds, but I now wonder if that is true or not. Yeah, turn on a machine w/o a heatsink :) In a couple of seconds it will get so hot that you can't touch it and the internal safety threshold on the proc will shut it down. I suspect the mobo might have a bios that can control the fan speed and the hysteresis or whatever technique it uses to control reaction time. My Asus has this IIRC... jlc _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
