290X non ref coolers have to run higher fan speeds than 780Ti non ref coolers to get the same temps though:
Same temps, more noise due to higher fan speeds.
It's just harder to remove the same amount of heat from the smaller hawaii die. Just the transistor density doing its thing.

Hawaii runs hot because of the low fanspeed on stock cooler.
Hence not the samething.
Fermi was perfectly fine on non ref coolers. Just like 290X. Both are just really bad on blower coolers.
And the 290X fan speed is definitely not low on the reference card. If it was we wouldn't have the hilarious jet engine videos on youtube.
