The PS5 Cooling fan is a must-have for everyone, in my opinion, given the fact that the PS5 doesn't have a proper exhaust fan. I have just installed it, and it immediately started blowing out warm air, a sign that it does it's job well.
It is made from nice quality plastics, not cheap to the touch, and the color scheme (if you opt out for the white one) blends excellently with the console itself. The blue LEDs are a nice touch and they function as an indicator for the speed of the fans, as well.
Now, about the noise. Keep in mind, i keep the fans at full blast. Personally, i do not mind it. If it runs in a room with some backround noise, like if one lives in a city and the window is open, it blends in well with the backround noise. However, if the console runs in a quiet room, you will hear it, no doubt. Not enough to interfere with the game or movie/tv show that it's playing, though.
Also, i am pleased with Kiwihome, as well. Everything went butter smooth. I received the fan in less than 2 weeks, shipped to Romania.
