It's working fine now, stable as a rock after hours of Crysis gaming sessions and leaving Furmark running overnight, but it's obvious there are major heat buildup issues with these cards if you're going to use air cooling.
That's a band-aid you've used... The card shouldn't overheat like that under any circumstances... You had to use water-cooling to prevent a faulty card from shutting down...
