When building tiny ITX/Small Form Factor computers, the choice of power supplies is not exactly vast. The Silverstone FX350-G is one of the few available that will fit a tiny case, and provide enough power. The problem is, the stock fan is ridiculously loud.

I found a few posts online from people with the same issue, who attempted mods using various fans. Obviously I opted for the Noctua NF-A4x10 FLX, because Noctua are the gold standard in quiet and powerful cooling, although expensive, and I use for everything I can.

Visible above, I took the opportunity to install the fan as an intake, so it will pull cool air into the PSU, as opposed to pushing hot air out.
