I have an older ps4, im pretty positive its fans need to be replaced and probably a few other things, do you guys do repairs like those?

Yes. Phoenix Games offers repairs on Xbox One, PS4 and Nintendo Switch systems. Please give the store a call (925) 682-4263 for details. Thanks for getting in touch. Phoenix Games

Your best bet is to call them directly, but I don't remember seeing service offered. They do polish and repair disks, but I don't know about hardware repairs.

Im not sure it does not say anything at their store.
