No, but it will heat the rad. My cards are aimed at a wall which is about oh 4-6 inches from the back of the case and they still run a decent 75-80C at %100 load, however the heat outside the case... well... it's VERY warm. I'd say it's a localized 90F behind the case. I also have my exhaust going out the back. It heats my room if I game for more than a few minutes.
So by aiming cards at a rad, you will heat the rad.
