HAVN H18 PWM Fan Kit, Fluid Dynamic Bearing, 180mm, 2-pack, Black

This dual pack contains two 180mm fans engineered to provide substantial cooling capacity for large PC enclosures or complex radiator configurations. The design incorporates a 40mm frame thickness, which supports deep fan blades necessary for moving high volumes of air efficiently. Operating at a maximum speed of 1300 RPM, each unit is capable of generating 164.63 CFM of airflow.

The performance profile of the H18 is optimized for both static pressure and flow rate, featuring a maximum pressure rating of 2.19 mmH2O, suitable for restrictive filters and radiator fins. Speed control is managed via a standard 4-pin PWM connector, allowing rotational speed to be dynamically adjusted down to 0 RPM. The unit relies on a Triple-Groove Fluid Dynamic Bearing (FDB) to ensure operational longevity and minimize mechanical noise, which peaks at 35 dB under full load.
