The Arctic P12 120 mm fan shovels at 1,800 rpm, producing 56 CFM AND a static pressure of 2.2 mmH2O. The connection is made via 3-pin, whereby an optional control is possible. Unlike other low-cost fans, Arctic has a high quality FDB bearing. This not only guarantees quiet operation, but also ensures that the volume does not increase over time. With a huge warranty period of six years this shows the quality and reliability of the fan. .
