Gigabyte ds3 undervolted? can't shut down

[enclavesaga]

Just got a new DS3, rev2.0, for some reason my ArcticCooling freezer7 Pro fan is not spinning(it jerks on and off every other second)usually needs to finger it to jump start and keep it spnning, even when it's spinning, it's very slow, RPM is around 300. I wonder if this a under-voltage problem and how can i fix it. everything else runs Okay.
oh, and btw, it takes forever to get into standby mode or shut down, any fix?

System:
C2D 6600, 2gb OCZ platinum 6400, 1950pro, Seagate 320, WinXP.

Thanks folks.

There's a bios setting to enable/disable the thermal control of the CPU fan.
Set to disabled, and the fan runs continuously.
