How does the NL-ACF1 compare to other VRM fans?
Many liquid coolers use 40–60mm fans producing noise and reducing airflow. NL-ACF1 uses open 80mm impeller for stronger airflow and quieter, lower-pitched sound.
How our SecuFirm2+™ mounting system enables NL-LC1 coolers to achieve lower temperatures
Our SecuFirm2+™ mounting system ensures optimal force transfer and contact pressure, which can give the NL-LC1 a slight edge over other Emma V2 based coolers.
