Noise Levels and Fan Speeds

Testing Procedure

Fan noise testing is done at 25%, 50%, and 100% fan speed, with the dBA level being recorded by a Pyle PSPL25 sound pressure level meter at a distance of 30 cm from the fan(s). The fan(s) RPM results are taken at the same 25%, 50%, and 100% settings. These speeds are handled by MSI's Command Center software, and a Lamptron FC6 fan controller is used as a secondary method of confirming RPM and dBA readings in case MSI's Command Center cannot control the fan(s), which ensures that proper results can still be obtained if the software fails. To give users the noise profile of the tested CPU cooler, testing is done using fan-speed percentages instead of various load levels.
