Noise testing is done at 25%, 50%, 75%, and 100% fan speeds, with the dBA level being recorded by a BAFX 3370 digital sound level meter at a distance of 15 cm. The fan(s) RPM results are taken at the same 25%, 50%, 75%, and 100% settings. ASUS AI Suite is used for fan control in order to give users the overall noise profile of the tested CPU cooler.
