Coolermaster Hyper TX2 Heatsink Review
Coolermaster position the Hyper TX2 heatsink as a "total cooling solution," which is a fancy way to say exhaust airflow is put to use. Behind the Hyper TX2 is a rather large air scoop. It's job is to direct airflow exiting the aluminum fins of the heatsink down towards the MOSFETs, chipsets and other circuitry positioned around the CPU socket on many Intel and AMD motherboards.
