NL-ACF1 Aux iliary cooling fan  Airflow for near-socket componentsProvides extra cooling for VRMs, RAM, M. 2 SSDs and other parts Ultra-quiet 80mm fanHigh performance at minimal noise levels, easy to control via PWM For Noctua NL series coolersCompatible with NL-LC1 liquid coolers The NL-ACF1 is an auxiliary cooling fan for Noctua’s NL-LC1 series all-in-one liquid coolers. Installed on top of the CPU block, it provides extra cooling for VRMs, RAM, M. 2 SSDs and other near-socket components. Its large, highly optimised NF-A8 impeller delivers significantly more airflow at lower noise levels compared to smaller VRM fans. Leveraging the Coandă effect, the NL-ACF1’s outer frame has been custom-designed in order to draw as much air out towards the components as possible. The fan can be easily adjusted from near-silent operation to maximum cooling via PWM, either at a fixed speed setting or through automatic control by the motherboard. Attaching magnetically to the top of the CPU block, it is extremely straightforward to install. In sum, the NL-ACF1 is a perfect add-on for Noctua NL-LC1 series coolers that are running in systems that could benefit from extra airflow over near-socket components.  Key specificationsSize (Form factor)80 x 80 x 25 mm (round)Speed range0 – 2200 rpmAirflow (max. )55.5 m³/h (32.67 CFM)Acoustical noise (max. )17.7 dB(A)Static pressure (max. )2.37 mm H₂ORated voltage12 VInput power (typical)0.75 WConnector4-pinColo urBrown
