I did not look for the CPU this machine has. My notebook has a i7 and it runs on 96 degree centigrade when the CPU is under 100% load. It would shut down at 99 degree centigrade. > > uname -a > FreeBSD bsd.laptop.mike 9.1-RC1 FreeBSD 9.1-RC1 #0: Tue Aug 14 > 04:25:06 UTC 2012 > root@farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64 > > There's my dmesg message: http://slexy.org/view/s21b7xTTsu > > Anyone knows how to fix this problem? Thank you. I do not know much about the differences between i3 and i7 but I would expect that both can run until 99 degree centigrade before they have to shut down. Erich
