The Cooler Master GeminII S524 is equipped with a single 120mm fan but can also use a 140mm fan. The CM GeminII S524 improves upon the RAM module clearance issue of the GeminII S by having 47mm height clearance between the motherboard and the aluminum fins. The Cooler Master GeminII S524 uses the same five 6mm copper heatpipe design employed on the GeminII S but now comes nickel electroplated for improved conductivity and corrosion inhibition. The supplied 120mm PWM fan can operate between 800 to 1800 RPM, designed to perform at a low noise decibel range between 15.1 to 31.6 dBA. In terms of versatility, the Cooler Master GeminII S524 can be mounted in various orientations and is compatible with Intel socket 775 up to 1366 as well as AMD socket AM2 up to the latest FM1 and upcoming AM3+ sockets.
