Cooler Master's RR920N520GP "Hyper N520" combines a stylish elegant design with silent operation and a brilliant cooling solution. Designed to cool the full range of current Intel Socket LGA 1366 775 and AMD Socket AM3/AM2/AM2 processors it does so with gusto. It features a unique split fin design that puts more surface area within the space cooled by over 43 CFM of airflow from the dual 92mm fans. A selection of mounting components allow the user to obtain the optimal installation of the cooler to the motherboard so that the cooler's copper base is snug against the CPU's heat spreader. Five 6mm Ushaped copper heat pipes draw heat away from the processor up to the array of aluminum convection fins which they support. The heat is dispersed at a silent 19 dBA by the fan which spins on longlasting sleeved bearings.
