Noctua NL-ACF1 computer cooling system

Noctua NL-ACF1. Type: Fan, Fan diameter: 8 cm, Airflow: 55.5 m³/h, Maximum air pressure: 2.37 mmH2O. Product colour: Brown

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.
