Sound Level Testing
While we were testing cooling capabilities, as outlined in our recent introduction article, we were also tracking the sound level of each of the coolers using a Risepro SPL meter attached to a boom arm pointed directly at the fans of the radiator at a distance of 12 inches. We recorded the dB(A) level for each fan and pump speed tested. The ambient room sound level measured 33 decibels. Displayed below are the results of our Stock Clock Testing.
100% Fans
At maximum fan levels, the SilverStone AR01-V3 hit 48.2 dB(A) while the Cooler Master Hyper 212 EVO hit 51.9 dB(A). From a subjective perspective, both coolers sounded loud but not high pitched.
1500 RPM Fans
Dropping down to 1500 RPM, the SilverStone AR01-V3 is again in the lead at 40.9 dB(A) and the Cooler Master Hyper 212 EVO 4 dB(A) behind at 44.7 dB(A). The AR01-V3 was far less obnoxious at this fan level. In fact, it was getting into the comfortable range at this point.
1000 RPM Fans
When we lowered the fans down to 1000 RPM, the SilverStone AR01-V3 kept the lead with a value of 38.7 dB(A) but the Cooler Master Hyper 212 EVO is right there on its heels at 39.9 dB(A). At this point, the noise sounded like it merged with the background noise.
600 RPM Fans
Lowering the fans to 600 RPM, the SilverStone AR01-V3 and Cooler Master Hyper 212 EVO tied at 38.7 dB(A).
Save for testing at 600 RPM, the SilverStone AR01-V3 was far and away the quieter of the two coolers. Even at 600 RPM it still did an excellent job, it was just the Cooler Master Hyper 212 EVO was finally starting to get its noise level in check as well and they ended up tied. That is definitely a solid outcome for the AR01-V3. With that said, let’s move on and recap all of this for you today!
