My card can't do those frequency and I'm watercooled, so no noise problem here.
The stock voltage on the 980ti hof is too high for the majority of people. Not everyone even bothered to buy a water block for it, and to get a good result using a g12 and a good aio cooler you'll have to spend more than if you use the rajintek cooler. Plus there's another issue if the aio fails. I've already got one in my case, don't want another risk factor. I've tried ubdeevolting a lot of maxwell 980tis and most can handle 1.125mv @1400mhz core which not only gives much better temps, but even if you're under water it will help prolong the chip either way. Pushing higher isn't really worth it. The card can do 60fps 1440p without going into the 1500 region. In this day and age a 980ti can't contend with the top boys, so pointless to have it beefed up when it won't do anything more for most people
