A fan would be fine to cool it, only problem with that is the inside might still be warm, while the outside feels room temp. I've never really waited to throw them back on the charger and haven't had any adverse effects. You should be fine, but do it at your own risk for sure. With LiPos though, stuff like that isn't that big a deal like it use to be with NiMH and even NiCads.
