I’m trying to replace the jet engine fan inside the PSU of a Nu 1.1 with a Noctua equivalent and am having trouble identifying the connector. The PSU is a Delta Electronics Model EDPS-250AB A, Part Number 400-5494-91.

I have taken several pictures of the fan connector and its header in the hopes of identifying the connection. I originally thought it was a JST-EH 2.0, but it is not, and the only means of comparison that I currently have.

    Any chance to replace the whole PSU and then going full tilt modifying the replacement? I only see one offer for 400-5494-91 (400€!!) so maybe any other in that form factor? Seems to be mostly standard PC connectors on these, but not sure from the pics I can find.
