Noctua NF-F12 PWM chromax.Black.swap, Premium Quiet Fan, 4-Pin (120mm, Black)

Not too loud, cool decently

Im two using these on my h105. At 100% speed theyre nearly inaudible in my case. Gets better temps than the push/pull config it replaced.

Best fans ever. Enough said.

These are great. I have just about all the fan changes out to noctua and it get quieter with each on I added even without using the low noise adapter. These are also cooling better than the original case fans.

1 star off for the price, as it really could be priced a little cheaper considering youre only getting 4 pads of a certain color. Otherwise, the Noctua quality is still there, super quiet and moves air for my U12S

Great, wires are a bit short so wiring was didficult

I have a Corsair H80v2 and could not stand the noise. I replaced the stock fans with these and it is much more silent now. Recommended.

These things are dead silent. I originally tried the Arctic P12 PWM PSTs in my build, but there was a very noticeable constant whining sound when they ran. These, on the other hand, are so quiet that you hear the air rushing through the fan more than you hear the fans themselves. It doesnt get much quieter than that.

Bought two fans, one to replace the stock rear fan (120mm) and the second to use as top exhaust inside Fractal Design 7 compact case.

To summarize my points before going into details:
