Alpenföhn K2 Dual Tower CPU Cooler Review

While situated in a room where background noise was kept to a minimum, we placed the sound level meter equal distances from our test system to measure the total noise output by the complete test system for each cooling configuration at 100% fan speed.

An acoustic output of 46.3 dbA leaves the K2 with a mid-table finish. It may not be ground breaking in terms of noise output, but its Wing Boost fans do utilize the very convenient 4-pin PWM headers making them silent at low load situations.
