Review on Noiseblocker NB ELoop B12 PS ARGB PWM by Adam Kotula ᠌

put in the case for blowing. At a speed of about 1000rpm, it makes worse noise than unname for 100. What kind of ultra-silent is there . a turboprop aircraft on takeoff. Through the experiment, it was possible to identify the following relationship: - by itself (open air) the fan is buzzing, but not much (and at 1000 and 1500 rpm) - when an object is located on the blowing side - the noise increases slightly - when an object is found on the blowing side (such as a mesh near the case), the fan starts to make a lot of noise, low-frequency hum and vibrations appear. Cured by cutting the perforation. Now the noise and hum have decreased by about 80-90%. In general, not silent, but very quiet. BUT EVERYTHING IS THE SAME - QUIET BUT HOWLING! Although the Arctic f12 pwn co is noisier, the sound from it is somehow "more comfortable", and it costs 3 times cheaper, and it cools better. So I returned it back to the store.
