Review on ARCTIC F12 PWM PWM Signal Regulates by Agata Nowickq ᠌

Compared with Deepcool GS120. During the test, both were connected to the socket on the motherboard, so the main test was not carried out at maximum speed. Also, for comparison, I connected both directly to the PSU once at a time - at the maximum, the flow for both is very good. At the same time, both are naturally noticeably noisy, but this is more likely due to a strong flow - the air makes more noise than the bearing - at high speeds this will be heard anyway. At low revs (1155RPM by SpeedFan), the Arctic F12 doesn't make any sounds, and the Deepcool GS120 has a barely noticeable overtone. Although the sound level meter does not see the difference between them (most likely because high frequencies are less taken into account in dBa mode), there is still a difference by ear. Therefore, in the end, I put Arctic F12 in the block. Some write that their Arctic F12 began to make noise after six months. I can only advise you to use air filters. Even the ancient Zalman ZP1225AFL worked for me for seven years and began to make noise only towards the end. In the attachment there are photos of the sound level meter with an open unit without and with a tested fan. To make the difference clear - these are very quiet sounds, at a distance of a meter from the computer with the case closed, the noise level does not rise above 28 dBa. All these sounds can be noticed only when the window is closed at night. Everything was bought for the sake of a silent computer, so it's critical for me. If the Arctic F12 starts making noise in the next six months, I'll write it here.
