Can an AC Installed make the engine run hotter than before?

Just reiterating what has already been stated.

Yes, the AC condenser will add a substantial amount of heat in front of the radiator, putting more of a load on the cooling system.

210 isn't bad at all, but as mentioned, it doesn't leave a large margin for error.

Do you have pics or details of the e-fan setup? Are they just strapped to the radiator? Or are they properly shrouded to utilize all available cooling area?

True to an extent, yes an internal combustion engine will run more efficiently and powerfully at a higher temperature until detonation becomes an issue.
