Help identifying a (proprietary?) PSU fan connector

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.

Why not just cut the wires and solder the connector to the new fan.
- I am trying to be non-destructive since this is a rare piece of equipment. So I would prefer to put in something entirely new in and preserve the original hardware in case something goes wrong.
  
  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.
  
  One possiblity would be to cut the original cable and add a new connector to both sides. A female one to the one that goes to the board, and a male one to the one on the fan.
  That way you have all the original parts still there, but you can use the one part of the cable as an adapter.
