I just bought a DFI LP Ultra-D mainboard and I am planning on leaving the stock heatsink fan on the nForce4 chipset. I was reading Mike Chin's review on the Antec Phantom 500 and he said he controlled the RPMs of that chipset fan via the BIOS. Can anyone give me details on where to find that option and any other information like if it does quiet it down and if the temps go super high if it slows down? I'm going to have a 120mm Nexus going full speed at the intake so hopefully some air should blow over it.

Thanks in advance for your help!

Its in PC Health Status. Something similar to this:

It says in the manual:
CPUFan Turn Off If CPUTemp
This field is used to select the CPU temperature that will allow the
CPU fan to rotate at a start speed which is the slowest speed.


Anyone knows what exactly is start speed, or more specifically, what voltage is it supplying at this slowest speed?

If you have the ITE Smart Guardian installed (on the CD with the chipset drivers) you can adjust the fan to spin slower and set the full speed to start at a higher temp.

A friend measured starting voltage to be ~4.2V. I don't know if he got that right though.
