Ummmm... On the system I'm most interested in at the moment, which has
only _one_ athlon64 _single core_ processor in the whole system,
k8temp -n prints this:
19
10
So, this yields two problems:
1) Which number is the Right One?
2) Assming those numbers are given in C, both of them appear to be
impossible numbers. My motherboard BIOS is saying that the CPU
is running at around 39-40c. So even if the Right Answer from
k8temp is the bigger number (19) that's _still_ below even the
room temperature, I think. In short, it looks like useless non-
information. Do you agree? (By the way, I'm in California, and
it is summer here. It _ain't_ cold where I am. Room temp right
now is about 78F.)

Thanks, but I don't need fancy graphs.

I was hoping to find something that didn't touch disk (nor use up all of
my remaining space in the /usr partition). I think I'll wait and try to
learn more about mprime. But thanks.
