It makes noise, yes, but it is cheap, does its job very well, and has a 5-year warranty. For someone who doesn't care about RGB and just wants fans that work, I recommend it. I have 5 F14s and one F12, and they have significantly lowered the temperatures. And even though it sounds like a turbine.

Unacceptable noise. The PC doesn't make this much noise even when it's at 100% load. I had it on for 5 minutes and it immediately started making noise again. I will try using the same one with a 4-pin PWM so it doesn't work at 100%. It cools very well, I must say, but the noise is excessive.

I placed it in a Cooler Master 690 club case from 2009, on the side panel, above the GTX 960 4GB Windforce graphics card, on which I have done a slight overclock (+200MHz on core+memory). It reduced the temperature of the graphics card during gaming from 52°C to 42°C. Outside of games, it stays at 23°C. I believe it is excellent for its price (4.60 euros). It is not completely silent, you can hear it, but not annoyingly (you just hear that a fan is working). I consider it an excellent purchase in terms of performance and price.

Also, since obviously the air it blows doesn't only go to the graphics card, but also reaches part of the motherboard, it lowered the system temperature by 6-7°C.
