I've done a fair number of hours of gaming on mine and haven't heard a peep, but there are a couple caveats to that; first, a large chunk of my gaming was on CS Source, which is hardly taxing to a 980 ti even maxed out; and second, it's been really, really hot in my apartment, so I have a lot of fans and an air conditioner running, which means lots of ambient noise. But I haven't heard the 980 ti over that! It seems quieter than the EVGA GTX 680 it replaced.
