Update 28-12-2016: I got my repaired video card back and its an huge improvement, much more quiet now. Great service at Gigabyte!
I did some cleaning up and a bit of pimping of the case and some fiddling with the fan speeds. At load the there is a lot of over pressure and really helps smash out the hot air from the video card exhaust, I have tried and seen the difference. It resulted in a bit higher case fan speeds and lower GPU speeds resulting in less noise.
My only regret is not investing in a better PSU (read: more silent). Although it is at idle only barely audible I would have liked to have a bit more silence.
Things I would do different or advise are:
Edit: Because Vader, all hail the Empire!
I finally got the funds to put away my 5+ year old pc and build a new one.
I wanted silence (my old one was noisy) and a small case. After some looking around I settled on the Nano S its looks, cleanliness es and simplicity won me over. Edit: its also one of the few small cases that lets me have only filtered intakes for my fan set-up. The main problem on silence would be my graphics card. After some discussion on stock cooler or aftermarket I went for an aftermarket cooler with an additional fan beneath it to help the airflow. Combined with a heavy over pressure. Oh does it work! :) On the graphics card, the case nearly fits anything and I game at 1080p so I got an 1060 instead of a 480 just because of price at that point, but would have gone with a 480 just as easy.
This build requires a fanhub and helps moderate the fan speed from the CPU fan.
I am very happy with how the build. Its clean and I like the black and white theme. Also when browsing or watching movies my graphics cards fans don't even spin because it does not get above 40 decrees Celsius because of the excellent passive cooling. I even had to lower it from 60 to 40 because I might otherwise think my card would be dead :p
