This is not what I suggested before. I thought I was pretty clear but let me be very clear.

The best chance you have of doing this right is to actually slightly peel the label back where the wires are on the fan's body. Where are the wires are soldered to the circuit board of the fan sometimes have stencil marks/labels. That will tell you what each wire does. You want to mimic that on your new fan. So even if they've rearranged the signals, you want the proper signal on the proper wire.

Check for stencil labels where the wires are soldered to the circuit board of the fan by slightly pulling up the sticky label on the fan!

Do not attempt to remove the entire label, it will not reattach back properly and if you have an oil port you'll be exposing the oil port. Only lift as much of a label around the wires as required to expose their soldering points.

Then simply unsolder the old wires, from the broken fan, and solder them onto the new fan body in the correct order! Do not splice.  You want to match what was there but when they make new models of fans they can switch up the wiring order or even the purpose of what a color used to mean so please check what each color wire terminates to on the fans PCB, some symbol or stencil on each pad or wire is soldered on the fan. Do you want the old wires in the correct order to attach to the correct solder pads on the new fan that have the same stencil marking for the same function.

Luckily, it looks like you only deal with three wires and not four. So there's a large probability that the white wire is the same function as the yellow wire in the original wiring. I would still do what I stated above. Do you want to match the pads to the wires not the wire colors. The colors can be reassigned by the manufacturer. Make sure the pad with the plus goes to the same wire that had the plus on the old fan, the negative or ground wire on the fan went to a negative marked pad on the old fan, etc.

Don't splice, de-solder the entire wire harness from the fans PCB body and attach the old wiring harness to the new fan where the signals are correct based on the stencil marks between the two fans.
