The Scythe Big Shuriken heatsink stands just 58mm high, but uses a large 120x120x12mm fan to get the job done. Scythe built this heatsink specifically for users with low-profile cooling needs, like MicroATX motherboards or book-size PCs. The Big Shuriken heatsink weighs 405grams, has four heatpipes and fits Intel 775/1366 and all AMD processors. The fan rotates at 900-1600RPM, moving about 40 CFM.
