Extra cooling for near-socket components

With liquid coolers, there is typically less air movement around the CPU socket than with air coolers, which can cause higher temperatures on near-socket components such as voltage regulator modules (VRMs), RAM modules or M.2 SSDs. The NL-ACF1 solves this problem by providing extra airflow to the entire area around the CPU socket.

Large diameter NF-A8 fan

Many liquid coolers use 40 or 50mm VRM fans that produce high-pitched noises and are hidden underneath a cover, hampering airflow. By contrast, the NL-ACF1 leverages an 80mm size impeller that’s completely uncovered, which ensures both superior airflow and quieter operation with a more pleasant, lower-pitched sound signature.

Coandă effect for maximum efficiency

The NL-ACF1 combines the proven NF-A8 impeller with a custom-designed fan frame that leverages the Coandă effect, the phenomenon that fluid streams have a tendency to stay attached to surfaces, to draw airflow out towards the sides as much as possible.

Magnetic attachment

Installing the NL-ACF1 couldn’t be easier: Thanks to the integrated magnets at the base of the fan, it simply snaps onto the NL-PNA1 pump noise absorber of Noctua’s Asetek Emma V2 based NL-LC1 liquid coolers.
