General Specifications
Cooler Master
About the Product
The Cooler Master Mega flow has a diameter of 200mm and displacement volume of 184 M3/h, which is twice that of 140mm fans. These specifications allow excellent cooling and silent operation.
While more and more PC cases support 20cm intake, side-panel or exhaust fans, many of the bundled stock units and available aftermarket options are of questionable quality. By contrast, the NF-A20 is a true premium grade solution worthy of Noctua’s award-winning A-series.
