While on the subject of tempertures, I found something a bit weird. In linux
with C1 disconnects enabled, the system temperature was 36 C. I rebooted to
BIOS setup and watched the temperatures there. For some weird reason, the
system temperature rose from 36 C, to about 41 C. And I also watched the CPU
temp rise from about 41 C to about 51 C ! I boot back into linux, and I watched
the system temperature _drop_ to 36 C again. What is C1 disconnects disabled
during POST now on my BIOS? I have done this before when I first got it and
never noticed something like this.
