Temp in Bios wrong ?

[Orv]

I just built this system and when I check the CPU temp in Bios it fluctuates
between 176f and 180f. Obviously this is incorrect.

The Asus MB is brand new (even though it's outdated). The processor was
pulled from other system. The graphics card, RAM, and the PSU are all brand
new. The BIOS has the most updated version (checked ASUS website.

I replaced the original Intel CPU fan and heatsink with a new one and still
get the eroneous temps. I've checked and re-checked connections and RTM (2
or 3 times) re the MB and everyting looks ok. I tried to even load failsafe
defaults, still same crazy temp reading.

Any suggestions would be helpful.
Thanks,

There's a really good utility called SiSoft Sandra. See if you can
get/borrow/buy a copy and try it. If it's possible to do so, it will
give correct readings on temperatures as well as most other parameters.

OK, I used the jumper to clear the cmos....no change. I also was able to
install WinXP by setting the temp monitor to ignore (in the BIOS). I also
installed the ASUS MB utility which shows the same temp as the BIOS. I'm
lost as what is causing this.

According to this, it is a function of the BIOS revision being used.
The older BIOS revisions report temperature properly. Later ones do not.

But even if we subtract 20C from your temps, the temps are still too hot.

Ok, I downloaded the last BIOS and still the same thing. I even went all the
way back to the first BIOS, same thing.
Thx for all the help but it looks like an RMA is my future!

I can't see how the Asus utility could be affected by BIOS issues. I
would think that it would query the hardware monitor chip directly ???

Maybe the OP could try another monitoring utility, eg Speedfan,
Everest, or Motherboard Monitor. The latter can produce a debug dump
of the chip's data.

Here is an article that talks about a bogus AUX temp of 180degF:
http://www.lavalys.com/forum/index.php?showtopic=1525&pid=8218&mode=threaded&start=

Motherboard 28 °C ( 82 °F)
CPU 38 °C (100 °F)
Aux 82 °C (180 °F)

This is the motherboard manual:
http://dlsvr01.asus.com/pub/ASUS/mb/sock478/p4v800d-x/e2221_P4V800D-X.pdf

The BIOS screen shows only the CPU and MB temperatures, but the
hardware monitor chip (Winbond W83627EHF/EHG) has three temp inputs.

Maybe the later BIOS versions have swapped the CPU and Aux sensors. If
so, and if Asus Probe has a configuration file (as does Motherboard
Monitor), then perhaps the OP could edit it.
