The Sunbeam CPU cooler utilizes the proprietary Core-Contact technology, which places the four heat-pipes in direct contact with the CPU for the most efficient heat conduction. The four thick 8mm heat-pipes combined with the top-rated TX-2 thermal paste, and the industry first ultra-silent, ultra long life MFDB (Magnetic Fluid Dynamic Bearing) cooling fan with speed control offers great value and industry leading cooling performance with peace and quiet!
