Coolermaster's GeminII M4 CPU Cooler is engineered to maximize cooling in small form factor systems. In combination with its four heat pipes and a unique heat pipe design, it directs the flow of heat more efficiently to the aluminum fins where the heat is dissipated by the slim 120mm fan. The GeminII M4 features a 90 degree airflow design rotated to avoid heat radiating from the motherboard. In turn, this orientation simultaneously provides a steady airflow to motherboard chipsets surrounding the CPU socket.
