I have two 5850 cards in crossfire, the primary one (first attached) has its fan blocked by the second card, so it easily runs up to 90* C, and above 100 if I don't decrease so it only runs at 100-150 Mhash/s as oppose to 280 Mhash/s.
Both cards run at 100% fan speed, removed the tower side for better airflow and mounted a fan to point directly at them.
I only wanna OC the secondary card, as I use the primary one to game on (or so I think at least, I assume it uses that as the second already is under heavy activity?), should I downclock memory and increase GPU Clock?
