You're assuming ALL people buying the Fury X already have a CLC in their system. For some, this will be their first experience with this. They'll slot it in and then scratch their heads because - it's a completely new noise. They know how fans sound, but this water cooler is annoying.
To those that have CLC they'll rip it out because they'll know from their own experience it's a bad design/faulty design. So, I still don't get the analogy you're trying to make.
You got people using tricks to make it more tolerable. Isn't that a shame, after dishing out $650? If any of the CLC's I bought made the kind of noises I heard for the Fury X they would be back in the box and I'll write them off until I get another itch. Sitting here 2 feet from my rig and all I hear is the light sound of wind. Even when I play a game with ref 980 ti fan profile, it doesn't get loud. (They made a huge sacrifice in my opinion cuz that card can throttle like the dickens!)
I am not assuming anything. You seem to be reading something I am not writing. The pumps in the R9 Fury make a noise that I personally would find annoying, so I am not defending the card. I am simply pointing out why its likely such a big problem to so many people.
Because the card is so quiet, the noise stands out in ways it otherwise would in a typical case. The 980 ti is a much louder card, but because the noise it makes is low its not considered to be a problem. People accept low frequency noises. High frequency noises are sharper. So a high frequency noise loses energy faster than a low frequency noise. So when you put a high frequency noise in a case, it dampens much faster than the typical low frequency noise.
Now, take away the ambient low frequencies and remove the side of the case and that high frequency noise will stand out. The analogy I made about the auto industry was with low frequency noises, but I was showing how making things quieter made other noises seem louder when they were not. The card by every review I have seen is very very quiet. The issue is not with how loud the card is, but the type of sound it makes stands out. Couple that with the quiet fan and it will feel much louder than it actually is.
