Coolant boiling out?

sounds odd about your fan... if your ignition is off but the bike is that hot the fan should continue to run... (at least it does on my bike and every car I've ever owned)

I'd look into that. if your fan isn't running after your bikes off... that's your issue... and potentially a big one... Heat soak is on joke... just becaue the motor is off doesn't mean the bike isn't still heating up... after a good high speed run if you stop you bike and let it sit with the motor off the heat will continue to rise for a couple minutes... same in cars.

Weeeeeeeell, technically, the heat will not rise after the engine is off, but the coolant temperature will rise as it absorbs the energy from the metal, which can cause a boil over. The purpose of the catch tank is to prevent spillage in the exact case described. A spill over could occur if the engine was extremely hot (doesn't sound like this was the case), or if there was too much coolant in the system (don't know if this was the case). I would look for leaks, check the level in the overflow tank, and go from there. I doubt you have a serious issue, but better safe than sorry.
