Going into the testing for the R7770 I was a little apprehensive. Our experience with the dual fan R7970 was okay but had noise issues at idle and cooling performance while overclocked wasn’t as good as one would hope. Surprisingly when running the R7770 through Furmark I couldn’t hear the card at all. This combined with a temperature of 63 under load are very impressive. Cranking up the fan speed might even give you even better cooling, not that you would need it.
