Abit IC7 Temperature Monitoring Problems
Just finished setting up an Abit IC7 - P4 2.8C systems. With either Hardware Doctor (Intel) or Motherboard Monitor 5, I cannot reconcile the observed software-indicated CPU temperature with the BIOS-indicated temperature.
Specifically: After running the system at 100% CPU usage, I can restart, enter the BIOS, and CPU temp is an indicated 60*C (yeah, crappy $3.00 retail stock heatsink). With MM5 and Hardware Doctor, this is indicated to be 95*C. Obviously, it isn't running that hot, or I wouldn't be able to use the computer.
I've completely removed both MM5 and HD, and reinstalled the latest versions. Are these programs incompatible with the IC7's Canterwood chipset, or with the Abit's Winbond sensor configuration?
Also, the BIOS gives three temperature readings: 1) System, 2) CPU, and 3) PWM. PWM registers consitently in the BIOS and in software as between 45-47*C. Is that perhaps really the reading for the CPU? Seems a little low for 100% CPU usage with a cheap heatsink, doesn't it?
Any suggestions or links would be appreciated.

"Since the temperature is “calculated”, not “measured”, the formula which the BIOS uses will make the outcome different. There is a parameter that is provided by the I/O chip vender, which we expect it to be the standard, so we use this parameter to calculate the temperature of the processor. Once this parameter in the BIOS is changed, the temperature shown in the BIOS PC health or in the hardware monitor tool will be altered. But, in the mean time, the actual temperature of the CPU is still the same. So the temperature you saw might be higher comparing to other motherboard with the same chipset, it is because we use the different parameter to calculate the temperature. We cannot say that we are more accurate, but we sure follow the standard provided by the I/O chip vender, and we believe it should be the proper one."
in other words, if im reading this right, then the IS7/IC7 give you the REAL cpu temp instead of what we normally see, so subtract 10-15 degrees. about the winbond sensor, i dont know but my winbond 2 can only be read by the hardware doctor, and MBM5 locks up my system trying to read it
Sorry, Barron, started on thread as indicated above. Pasted your reply there.
