Average Noise
The PSU’s average noise output is low, not exceeding 19 dBA.

The semi-passive mode lasts much longer than the higher-capacity models of the line, and it is not affected by the load on the minor rails. Up to around 190W at 12V, the fan doesn’t spin under normal operating temperatures. At around 660W at 12V, the fan’s noise exceeds 20 dBA and goes over 25 dBA with more than 760W at 12V. It never exceeds the 30 dBA mark. All in all, the fan speed profile is relaxed.

The 230V fan speed profile is identical to the 115V one.

I noticed that the test results, especially the fan control, differ between this review and the report 24PS2426A for same model. Did the review test a new revision that is not yet on the market?
Seems, I found the relevant report – 23PS2308A. This appears to be an earlier revision of the power supply.
I can use a different test sample than the one listed on Cyben
