There is a fuse (F13 - model # 2A32V-9-GP) that is in the power supply to the fan. Perhaps it blew somehow after the power was reconnected, (accidentally knocked off board during repair?).
I don't know where it is located on the motherboard as I can't zoom in far enough on any images of the motherboard I have found online. Hopefully it is designated on the board.
Below is an image taken from p.66 of the [document|40800|schematics] for the motherboard showing the fan control circuit that may help.

If the fuse is blown, unplug the fan from the motherboard and use a DMM (digital multimeter) to check if the replacement fan is OK i.e. correct resistance value between the fan's red and black wires (fan motor). Also that the red wire is not short circuit to earth (fan frame, other fan wires) as well

Also, and I don't see how it would prevent the fan from operating, but according to p.84 (92 of 176 pdf) of the [document|34787|hardware maintenance manual] when installing a new thermal device/fan there are two pieces of film that need to be removed from the rubbers of the thermal device as well.
