Meanwell LRS 350 Noctua NF-A9-14 ventilated cover

Noctua NF-A9-14 90mm fan cover for Meanwell PSU.

Although intermittent, the stock fan on the Meanwell LRS 350W is loud when running. Switching it out for a 90mm noctua fan significantly reduced the fan noise.

I've reduced the hex mesh from the original model at the top of the PSU so air is channelled through the components before being exhausted.

The model has an internal hook for cable management. I ended up not using this on my own PSU. The fan should be mounted on the outside of PSU cover - there's insufficient space to mount inside.

I chose to trim the A9-14 cable to length and fit a new 2 pin JST-XHP connector. The A9-14 is a 4 pin fan, you only need connect the yellow (+) and black cables to the PSU connector. On my LRS 350 the positive pin was on the right hand side.
