3 Heatsink reviews from bit.tech
 

Surprisingly the lightest and quietest offering, Gigabyte's G-Power, performed significantly better than both of Cooler Master's heatsinks. The G-Power comes with an inline resistor to reduce its fan speed by 15%, it wasn't found to make much difference the final load temperature we measured or to the noise output of the fan - it was already one of the quietest components in our typical test system.
