Yeah, I wouldn't worry about the fans, usually it's not much more than a Hall effect sensor and a couple of transistors in them, IIRC. Depending on bearing type, there might be places that trap water though, potentially causing rust if it remains, so I'd shake them thoroughly in different directions and let them dry for an extended time.
