100% sure now that the noise comes from the Southbridge fan.
Other ppl have the same issue with this Asus A8N-SLi board, its a crappy fan.
I unplugged it to test, its SO silent without it but could the mainboard run without the fan?
Its a nForce4 Chip
I recorded the noise, holding the mic inside the PC.
It was the loudest when holding it close to the Southbridge...
2 MP3's with slightly different noises because it changes.

The temps have been fine, but I only checked in the bios. I only had that old motherboard monitor program but that didn't show the temperature anymore..
which one do you guys recommend?
But then again, since the noise usually comes when first starting the PC after it was the whole night off...
Yes the new fan does exactly the same noise. I opened the PC and checked closely to be sure its the CPU fan.
But you're right, I am not sure whether the noise comes from the fan running too slow. I had that in mind because of the bios warning, but that might not be correct.
Hello!
Last week when I first booted the PC my CPU-fan howled horribly.
I also had the message warning: CPU-fan speed too low.
I proceeded with F1 to windows and after about 2 minutes the noise stopped, CPU-fan was silent as usual.
My PC: Windows XP SP3
Mainboard ASUS A8N-SLI
AMD Athlon 64...
