I am going to wire 4 PC fans together. Can I use CAT5 cable or doorbell wire to wire the fans to the power supply?

Wiring 4 fans together brings up issues other than the cable, that's why you see fans wired individually in a PC, even if they're wired using a splitter.
Once you start wiring them together, you have to consider whether you're wiring them in series or in parallel, and then do the appropriate calculations based on your choice, and the fans' ratings.

They will be wired in parallel and connected to a 12V DC 2000mA power supply. I have used it this way for the last 3 years and it works good but I am rewiring a closet and was just curious if I could use the above stated wire.

Either doorbell or CAT5 should be ok. If I were doing it with CAT5 I'd use two pairs for + and two pairs for -.

All depends on the power supply and the voltage the fans operate at. Assuming they are 12v DC and you use a sufficient 12v power supply wire them in parallel. Each fan gets 12v.

Should be fine for a 12V system.

Cat5 would work fine, no need to run two pairs for each fan, it's 12v DC haha but do make sure you use cryotreated cable for better performance

Cryotreated. There is a tweak in every crowd.
