Won't that also make them noisier?
Looking at 1080s, I did find one card using this breakdown from Tom's: http://www.tomshardware.com/reviews/best-nvidia-geforce-gtx-1080-graphics-cards,4725.html
The MSI GTX 1080 GAMING X 8G. All of the other 3rd party cards had either noise or cooling in the CONS side.
From guru3d: http://www.guru3d.com/articles_pages/msi_geforce_gtx_1080_gaming_x_8g_review,11.html
The card is 12C cooler at load (impressive! it is warmer at idle, but meh to that), and 1db quieter at load and idle.
I would grab that card if I were buying a 1080. I'm not finding others with similar improvements, which ones did you find?
I'm seeing something similar with 480s. It looks like it pays off to be careful with manufacturer. MSI put out a couple kickass cards according to reviewers.
I'll take it back then. Many of the cards are crap, but some are clearly better in cooling and noise. 12C is nothing to ignore, that's significant. A couple dB is pretty negligible, but in combination with a drop in temp that's great.
