I find all custom PCs noisy compared to the 2013 Mac Pro I owned, which is what I truly consider silent.
Also having owned the 4870X2, GTX 470, GTX 580, ACX 980, the reference 980Tis in my H440 are quiet. Mostly down to the chassis as well. Both in SLI have the same noise levels of the reference GTX 580 I was using after I sold my 980 ACX.
Even so, the only GPU I experience as noisy as shown in that review video was the reference 4870X2 under load; or SLI reference 980Ti's with a 1-1 fan profile.
