A7N8X - Bios and Asus PC Probe Temperatures Quite Different !

[sgap]

Configuration:
ASUS A7N8X PCB v1.04
BIOS v. 1007
ASUS PC Probe v. 2.21.05

Asus PC Probe Temperature Monitor indicates :
29 C/ 84 F for CPU
46 C/ 114 F for MB
(I think there is an inversion between CPU and MB labels, but values seem
OK)

BIOS indicates :
46 C/ 114 F for MB
73 C/ 163 F for CPU
(The values are quite DIFFERENT..)

Where is the truth ?

I tried with older BIOS and ASUS PC Probe supplied with the CD, the values
were the same.
The labels weren't reversed on the version of Asus PC Probe supplied with
the CD.
The voltages values are the same in BIOS and ASUS PC Probe.

The BIOS measures the internal diode temp of the CPU which Asus Probe
measure the temp sensor under the CPU. However, the diff between the two
that you have is a lot more than what I have ever seen (it's usually around
15-20C). Also, your MB temps are really high, you should get them below 30C
if possible by adding some fans to the case.

The BIOS reading appears to be under heavy load, the Probe reading may not
be.

OP: use MBM5, it's distinctly better, see bottom of my FAQ for details:
