It may not be spinning fast enough. Look in your BIOS at the fan speed and see what it says, at full speed the cooler should be 2500rpm or so, unless the fan is automatically speed controlled, in which case you shouldn't see that error in the first place.

Yes, the Freezer 7 Pro is controlled by Pulse Width Modulation (PWM) not voltage adjustment like older adjustable fans. If your motherboard isn't compatible with this (has a 3 pin CPU power connector not 4), you ought to turn the auto fan speed control off or you could get heat issues, or damage the fan.
