The 120mm S-FLEXâ„¢ series from Scythe utilizes Sony's Fluid Dynamic Bearings to create a high quality fan with an incredible noise to CFM ratio. At only 34.0 dBA, the Scythe SFF21G (1900 rpm model) pushes an astounding 75.0 CFM! Innovations such as the S-FDB technology, additional suction magnet, and linear drive IC all contribute in eliminating noise and wear, drastically extending the life of the fan up to 3 times the amount of conventional ball bearing fans. The 120mm SFF21F S-FLEXâ„¢ fan from Scythe is great for any application; this 120mm fan pushes more than enough air for any case/heatsink application and is also recommended for radiator setups.
