Noisy PSU fan

I just replaced mine with an NF-A4x10 FLX like @PaulM did (following the video he posted).

  • It was very easy to install, but I didn’t trust myself squishing the wires into the PSU so I just left them hanging out (there’s a gap).
  • The fan doesn’t completely fill the space, so I taped over the gap with some electrical tape to preserve the air channel.
  • I can’t hear it so I’m not 100% sure it’s working, but I think I can feel the air coming out the back of the case.
  • The airflow is about half that of the stock fan, but the static pressure is double and, given that it’s trying to push through the PSU, I’m guessing that part matters more Wrong units, the air pressure is 8.5x LESS than the stock fan, so we’ll have to see how it holds up under load.

@PaulM your fan is backwards, from what I can tell. It should be an intake, exhausting air out the back of the PSU.

@wolfie you want the NF-A4x10 FLX. It’s 12V, 3 pins, and comes with a kit to splice it into any 2-pin connector. My existing fan was an AFB0412SHB, per your findings.

Disclaimer: don’t do this mod unless you’re comfortable losing everything, including your house. I only did it because the sound set my teeth on edge.
