So first thing, the cards work great at 1440p. Secondly, during gameplay I hear the fans revving every couple of seconds or so. It will go up for about 5 seconds, then come down for a while. I tried applying a manual fan in the EVGA precision X tool and the manual fan will work, but I'll still hear it rev to what sounds like 80% for brief stint and come back down. Any thoughts on this one? For now, I set everything back to default, then rebooted and made sure that no EVGA tools were running.
