290 Temp VS Power Consumption

I'm not sure what you are getting at.
Power consumption does not change with cooling, or maybe it does a little for the worse; but more power used means more power for gaming.
And more heat, so you can increase the voltage and powertarget further with watercooling.
In the words of a certain overclocker: "Forget the damn powersaving this is overclockers not greenpeace!" ;D

Temp's can effect power consumption fairly significantly, though in this particularly circumstance I wouldn't expect drastic changes, very possible for the power to reduce a decent amount. Thing is you usually get the same measure off a system that has a changing number of fans plugged in. So a third party cooled version might use 5W less power because it runs 10C cooler but has 2 fans that use 5W more and thus you see nothing.
Realistically to test it you want to use a third party cooler and attach the fans to a secondary power source, run idle and load and alter the running temp via the fans and compare power. Rarely does anyone bother.
Seems most here do not know the cost of the kw/h.
Even if the 290X was burning 100W more due to heat or overclocking or whatever, for every 10 hours at 100% load, it will cost you ~£0.09-0.12 (depending your provider and mine is £0.09).
Assuming you burn the card @100% for 5 hours per day = ~£16.5+vat PER YEAR.
Also there is a big discrepancy regarding the power consumption. Most sites (techpower, Tom's) saying tops 305W at 90% fan speed. Others like bit-tech 416W (doubt where they got their number from when everyone else says ~300)
So at 305W/h at 100% load, needs 3.27 hours to burn 1kwh = £0.10 (rounded up)
At 5 hours per day at 100% load, ~£0.153 per day x 365 days = £56 (round up) + 5% VAT.
Price depending your power provider, but all are around 8p to 12p per kw/h if you are in contract.
With the old "pay as you go" the top rate was 19p-21p per kw/h. + 5% vat
If you are a tree huger that counts the pennies for the electricity bill, go get a 260, and leave the rest to pay for the destruction of environment, with our burners.
