Query: Quieter then expected

Bought and installed on a Tyan Tempest i5000VF in a pedastal case with 2 Xeon 5130's. Even though the the Xeon's are only clocked at 2Ghz, and the PWM fans are controlled by the BIOS, there's enough copper and mass with these that they barely register as warm to the touch.
