Plasma Guns overheat a silly amount already. No, you don't need to roll since you never actual fire the gun. The Bolters find range for the Plasma if you need a fluff explanation.
I usually lose 3 Plasma Cannon troopers to self-inflicted wounds in a given game anyway, so there's no point making things even more ridiculous.
Sorry to be rude, but have you payed attention to the last couple of posts. The rules state if it is out of range, it *automatically misses*. this implies that shots have been fired and therefore the weapon can overheat even if not in range
