The LC-Power heatsink is active, which means it uses a fan to lower the processor temperature. Outputs 130W. For the heatsink to work properly, its output in Watts should be at least equal to the Thermal Design Power (TDP) of the processor. This will also help with the noise made by the heatsink fan, as it will not reach its limits. A cooler with a lower TDP than that of the processor will be less efficient, noisy and in the long run may reduce the life and performance of your processor.
