How cool and quiet does a 970 (custom/ref) run vs custom 290

[win8.1]

With the 970 being less power hungry than the 290 how much more cooler/quieter does any 970 custom cooled (or ref) run compared to say my Vapor X 290 and how much extra performance will they give?

My card in a system with little cooling (3 case fans+1 cpu fan) running below 1000rpm after 5mins of Unigine Valley levels off at 74c top temp and 41% fan (1858rpm) with a overclock at stock volts (+25 in Afterburner) of 1100/1400

With the 970 and it's lower power consumption and less heat to remove how much lower temps and fan speed and higher performance would it have compared to it using the same test even if tested in a system with better case cooling?

I use Unigine Valley as it produces the highest temps/fan speeds. Even more so than Heaven 4, Crysis 3 or any other game.

Maybe 970 users (custom or ref cooler) would give their temps/gpu fan speeds/case fan speeds and what they score in that test (including average/min fps.) when overclocked to the point where they would use it 24/7 and giving a good balance of performance/temp/noise.

Thanks.

They're won't be a lot in it to be honest as the Vapur-X is one of the best coolers on the planet.

My old 290 Tri-X was as quiet if not quieter then my new 970's

Ive gone from a 290 VaporX to a G1 980.

Even with this being a fatter gpu than the 970 its cooler, also when overclocked and the fans still on auto.

Vapor X is quieter I am sure.

I see. What benefit do you see performance wise or other compared say if you had added another 290 Tri-x or is it mainly power consumption that you changed for?

Could you test what performance you get with the 980 overclocked at clocks you would use 24/7 and the temp/noise/fan speed using Unigine Valley run for 5 mins. Thanks.

The 980 G1 would be a good comparison as it would be one of the best 980 custom cooled cards.

I would have thought with the lower power consumption and a good custom cooled 970 or 980 it would be better but there's maybe not much in it.
