High CPU temp with a Xeon 3060 (E6600) and Intel BX2 in BIOS

Can someone take the temp of their CPU using BIOS ?

My temp readings were higher than 60C in BIOS, and that's the computer
in idle with the stock Intel HSF (fan speed of 2600 RPM).

I replaced the stock Intel HSF, with a Noctua NH-U12F and Scythe S-Flex SFF21F (1200 RPM) fan, and my BIOS temp reading is still around 60 degrees
C.

That's way too hot. Mine is around 35 C. From what I've read 60 C is the at top of threshold. Can you see if the heatsink fan is spinning? Is the heatsink fully seated?

Sounds link the bios isn't reading the temps correctly!
Use coretemp in windows and see what you get! Coretemp reads directly from the temp diode inside your cpu's cores.

Thank you guys.

I didn't want to add any extra software to the new computer, so I always used the BIOS temp reading.

kenc51....Using 'Core Temp', it read 'Tjunction' of 85 degress C, and 'Core #0/1' of 43 degrees C.
The software read both cores, is small and removable after use.

If I had tried 'Core Temp' earlier I might not have replaced the stock HSF.

Sparky....was that temp reading from your BIOS ?

If anyone is interested, the Noctua (Noctura) NH-U12F, is a good HSF.
It's well engineered and manufactured. It comes with mounts for the LGA 775, AMD K8, and AM2.
It fits perfectly on an Intel D975XBX2. When installing just keep an eye on the fiber washers that measure 3/8 "
across - they are light and seem to get lost easily (took me over half an hour searching for it).

43C is perfectly fine! You might want to see if there's an updated BIOS available to download........but as always, if it ain't broke, don't fix it !

I use both Intel Desktop Utility:

And Intel Thermal Analysis Tool (TAT)

http://www.techpowerup.com/downloads/392/mirrors.php

TAT is nice because it shows seperate temps for both cores.

Mine seems to idle at 42, and I have fan control enabled, im sure if i forced it to 100% it would idle lower. stock X6800 heatsink.

Also, the latest BIOS, 2745, kills all users of ECC memory, so beware!
