The situation is still unclear at this point, but what is clear is this: some PWM controllers and the be quiet! Silent Wings 3 PWM fans do not get along very well. Unfortunately, this PWM control issue wherein there is a massive drop in fan RPM going from 100% PWM duty cycle to even 99% PWM duty cycle on the Aquaero 6 is not new and it has been covered in more detail here. The fans were individually tested and the results below are averaged with a standard deviation calculated.įirst up, I wanted to map out the RPM response curves to see if there was a significant difference between the fans controlled via PWM vs DC voltage control before measuring noise and airflow through the radiator. ![]() Fan noise was measured in an anechoic chamber of size 5′ x 8′ with ambient noise level ~19 dBA and a sound probe held 6″ away to measure the sound volume in dBA accordingly. Linear airflow was measured using an Extech 45158 Thermo-Anemometer 6″ away from the fan such that it measured the airflow in feet per minute through the radiator. ![]() ![]() Testing was done with the fan mounted one at a time on a single Swiftech MCR140QP radiator in a push configuration, with the fans controlled using a dedicated fan controller (Aquacomputer Aquaero 6 XT) in PWM or power (DC voltage) mode depending on the fan used.
