I went into the health section of my bios and saw a reading named "PWM
temperatures." This reading is the same one that is reported as case
temp by the sensor in MBM 5. However, if I start a program that pegs
the CPU, it is this sensor that rises faster than the reported CPU
sensor. What is the PWM temp? Thanks, Axel.

Hi folks,
I just put together a new box. AMD XP3000 CPU on an Abit KV-7 board.
The CPU temps are running between 45 C and 55 C, the case temps are
running between 55 C and 65 C. I can't think that this is normal. I've
never seen the case temps run higher than the CPU temps. This ten
degree spread exists even on a cold start. Could something be wrong
with the sensors? Any input would be appreciated. Thanks, Axel.

Its virtually impossible for the case temp to be higher than the CPU temp.
(Unless you have a massively overclocked GF6800Ulta video card and no
airflow!).

The two possible causes for what you see are either (a) the sensor are the
wrong way around. This is quite common. Or (b) the sensors are
miscalibrated. This is quite common too.

To check which it is, load the CPU up with something like toast.exe and
watch the temps. The one that rises fastest is the CPU temp. The case temp
will always move more slowly as it takes longer for the case to heat up than
it does for the CPU.

Having determined what the cause of the problem is (a) or (b), you can then
either swap them around in MBM or whatever. Or forget about it ;-)
