Noctua NF-A4x20 5V PWM, Premium Quiet Fan, 4-Pin, 5V Version (40x20mm, Brown)

noctua needs to fix the issue with 5v not being compatible with 12v pin headers.

I bought two of these little gems with the intent of installing them to cool a pair of NVMe drives. Instead I created a bracket to mount both to place on the front end of an Sapphire RX580 Nitro. I set the fan speed to the lowest setting in BIOS and now the main GPU fans never come on. Temps are always in the mid 20c. Now I have to buy two more for the NVMe drives.

I bought this fan for use with the Nvidia Jetson Nano. The Nano automatically turns the fans on and off on demand. Cant tell is the fan is on by noise generated because there isnt any. The only problem I had installing it was because the supplied screws were too short and didnt fit the holes in the heat sink. Temporarily used round toothpicks to hold it until I can find the proper screws.

I bought this for my NVidia Jetson Nano because it was recommended by the Geekworm case I bought.

easy to install, will buy again

Great quite fan with this and Igus Linear bearing cant here my printer run.

This is one of the loudest fans Ive ever heard. This is the kind of fan you would use in a server room where you dont care about noise. On the plus side, it does blow a substantial amount of air for a little fan.

I was replacing the 5v fan in a Netgear switch to be more quiet, but these 5V Noctuas barely move any air (Tried both the 4-pin and 3-pin version of the 5v Noctua.) I ended up putting in a 12V fan that starts at 5v (not Noctua) and it moves more air than the 5v Noctua without too much noise...

Works great!

Excellent fan but could have been a lower price.
