Compressor fan is making noise. is this an easy fix and where could I by the part?

I have owned this wine fridge since 2007 and up until recently I have had zero issues. Even now the wine fridge operates correctly, the only issue is one of the fans was getting rather loud. Pretty sure it was a bearing going bad, as others have noted they appear to be very similar if not the same as computer fans. I am happy to report that this evening I successfully replaced the loud fan. From what I could see It appears the fridge has 3 different fans. One in the upper back of the unit and 2 in the temperature control unit that resides between the red and white wine sections. The fan that was the issue for me was the larger fan in the rear portion of the temperature control unit. I figured out which fan it was by waiting until I heard the loud fan and then taking a plastic straw and sticking it into the fans to stop them and find the noisy one. Once I found the bad fan I was able to locate a parts list from the model # and locate the fan I needed. Getting to the fan was not as difficult as I expected it to be. This whole process took me a little less than an hour including the time to empty the fridge and refill it. The materials I needed were the replacement fan, phillips screw driver, wire cutters / strippers, soldering iron & solder, heat gun & heat shrink tubing, and duct tape.
1. Unplug & Empty the wine fridge
2. Remove all the shelves - they are held in place with plastic tabs on either side held in place with a screw. I loosened mine enough that I could spin them 180 out of the way. I actually ended up just tightening them this way so that I can now pull all of the shelves completely out whenever I want to.
3. Remove the 6 screws from underside of temperature control unit. 2 along each side & 2 across the back.
4. Open the wine fridge door fully out of the way. You should now be able to slide the temperature control unit forward an inch or so.
5. Remove the 2 screws from the top front of the temperature control unit. You should now be able to slide the metal cover towards you and remove it from the temperature control unit.
6. Good luck on this next part. You need to remove the very thin styrofoam cover from where the fan resides. This is what I had to use the duct tape for later to piece it back together. It is extremely thin and brittle.
7. Remove the one screw from the top of the fan that is holding the temperature sensor in place. Remove the 4 screws from the underside of the fan that are holding both the fan and fan guard in place. Other than the wire going under the styrofoam enclosure the fan should now be free.
8. Unplug the fan wiring harness from the circuit board, cut the wires close to the broken fan since you will need to reuse the wiring harness.
9. Feed the wires from the new fan under the styrofoam enclosure in the same manor as the old wires.
10. Solder and heat shrink the wires of the new fan to the old wiring harness and plug harness back into circuit board.
11. Reattach the fan with fan guard & 4 screws. Screw the temperature sensor back in place on top of fan.
12. Replace styrofoam cover on enclosure, like I said earlier I used duct tape to piece it back together the best I could.
13. Slide metal cover back onto the top of the temperature control unit and fasten back in place with the 2 screws.
14. Slide temperature control unit back into fridge and fasten in place with 6 screws underneath unit.
15. Replace shelves in fridge, you can replace the retaining clips as well if you feel the need and then plug the unit back in.
With any luck yours will run nice and quiet again like mine now does.

This WC model doesn't have a "compressor fan".
