EVGA Nvidia GTX 1080 TI FTW3 First Fan RPM Past 100%

My GPU has begun acting a bit goofy after it fell on its side in the EGPU case. I don’t know what to look for in terms of wiring or if there’s anything that can be done to resolve it.

When I look at my EVGA Precision X1 control panel, I can clearly see one of my fans is at 0%, but the fan itself is blowing full blast anyway:

And as you can see, none of the temperatures are reading anything too crazy:

So it seems like while there is no intentional signal going to the fan, it just is getting current, but the detector for the fan’s speed is still accurate. Which wire/wires would I look for? Or is this something that may not be addressable with just a computer superuser, and would actually require a vendor to look into?

Any help would be appreciated, my backup plan is to sell it on Ebay indicating the problem, but that it works fine otherwise, and buy a replacement.
