Intel's SpeedStep for Core 2 Duo

[caveman017]

Does it adjust fan speeds like Cool'n'Quiet does?

No, fan speeds are controlled independently.

How do I then have the fan speeds adjust then? I'm trying to build a "silent" PC, and don't want a loud fan or anything

You will probably need a 4 pin PWM fan for the CPU if you want fan control there. I say probably because some Asus boards built in the ability to control traditional 3 pin fans from the same 4 pin CPU header.

Once you've established that there should be an option in the BIOS to enable the fan control; some BIOSs just allow for on or off while others offer very specific options. Alternatively you can download SpeedFan to control fan speeds from within Windows.
