CPU fan not spinning on K8NXP-SLI

[adamu]

I have Gigabyte K8NXP-SLI on turning on the CPU fan spins briefly and then stops (good 4 noise bad 4 CPU) it continues to boot into windows and no warning messages. I leave the PC running for as long as I dare and then re boot, sometimes the CPU fan will start and continue to spin other time it stops again and I have to re boot .
The fan and HS are stock parts that came with the 3500 and the BIOS is version F6 the OS is XP Pro SP2 with all the C 'n' Q drivers,ect loaded and set.
Is this normal? has any one else experienced this? any ideas what could causing this and how to fix it? Cheers

Your BIOS may have a temp/fan parameter section.
My DFI did this (HSF fan would spin initially during boot but stop shortly thereafter) until I adjusted some settings in the BIOS.

What temperatures are you getting? Unless it's going really high, I'd say enjoy the quiet!

Having a cpu fan not spinning is generally considered as not good news, have a check in the bios as BUFF said, but if not, check you ahve it connected properly or there is something that you have missed.

CPU Thermal Throtling or something has to be disabled

Thnaks for the ideas it was a BIOS setting check the temps and setting around 20C though I'm not sure this is right . Ran super Pi for a while and fan started spinning :-) .

I don't think that that temp reading is correct !!!

Flash the latest BIOS to your motherboard !
