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. 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 also 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.

Noise Levels

The Reeven Okeanos is relatively quiet in most situations, proving near-silent with its fans at 25%. At 50%, it is still very quiet, and not until the fans hit 100% does noise become an issue. That said, adapters to keep noise levels in line at 50% have been included. As such, you get top-tier performance if you want it or a near-silent operation. Performance is still damn good with those adapters, so Reeven really covered all the basics thus far.

Fan Speeds

Looking at the fans' RPM readings at 25%, 50%, and 100%, noise levels match those speeds perfectly, especially with the maximum RPM of the 120 mm and 140 mm fans Reeven included. With the included adapters, users can also keep noise levels at around 38-40 dBA, so if you need a quiet cooler, the Okeanos does provide that option.
