By Bestbuy.comThe 120mm Slim PWM Cooling Fan is engineered for space-constrained systems, featuring a slim 15.6mm thickness. Its unique 9 scimitar fan blade design increases air pressure, facilitating rapid heat dissipation through radiators or heatsinks. Additionally, it serves as an effective exhaust fan, efficiently expelling heat from the system. The fan utilizes an all-copper Fluid Dynamic Bearing (FDB) for superior performance, low friction, and extended durability.
