82degree thermostat, cossie fan switch, manual fan overrride switch etc. all just delay the overheating. They don't improve the cooling one bit. I would also like to know actual solutions to the problem. With my GRS the temps sometimes climb close to the red area. In extream cases I just open the sunroof, turn the interior fan to max and turn up max heat. That will avoid the overheating of hte engine, but it will overheat the driver instead.
