You can't compare the running temperature like that. Both my 780 and 290 run roughly at the same temperature but the 290 kicks out a lot more heat to the room than the 780. I'd imagine that even if say the 970 runs hotter than a 290 that the 290 would make the room hotter than the 970.

That just means your 290 cooler is more efficient and transferring the heat away from the heat sink. If you stuck the Tri-x cooler on the 780 with the same core temp the heat transfer would be the same.
The fact it's heating up your room means the cooler and your case cooling is doing a very good job.

Or buy a 970 now then go 970 SLI when the 980ti hits and the flavour of the month boys are selling off 970's
Read my post again - I'm just pointing out to the person I'm replying to that running temperature doesn't necessarily mean anything. The 290 are hot cards. Ask anyone who's used one compared to a 780.
It also means the is more heat to transfer.

My 780 runs hotter than my 290. My 780 is reference my 290 a Tri-x.
So?
Edit: the point I'm making is that my 780 'ran' hotter than my 290 as well but the difference in room temperature is absurd.

It's because the 780 (if reference) has a small radial fan blowing the air out the back. The Tri-x has 3 large fans dumping the heat into your case and then your larger case fans sucking the hot air out.
If you had 2 heaters at the same temp in a room but one with a small fan and one with a big fan the one with the big fan would heat the room quicker.
It's all in the airflow....

There is a simple law of physics here, energy does not disappear. If you take 100watts of electrical energy you will get 100watts worth transferred to heat etc. It does not matter how efficient the cooler is the energy will be transferred to something somewhere 
If the base amount of heat being produced is the same that would be true but it isn't so it's a moot point. As I say read my original post again
. The 290 has more heat to transfer. They are hot cards. Not a bad thing though throughout winter but in summer it was a bit painful at times.There is a simple law of physics here, energy does not disappear.

Yes the more efficient the cooler and taking the heat and transferring the heat energy into the air the cooler the core will be but the hotter the air from the cooler will be.
The only real way to test would be to mount the same cooler to the 780 and 290 and then measure the temp.
I was just saying that with the reference cooler my 780 runs hotter than my 290 with a Tri-x cooler.
But then they wouldn't be at the same temp, unless the one with the bigger fan was putting out more heat

Look at it this way, two cards are running at the same temperature, one card is dumping more heat into the room, that card is therefore putting out more heat (and it's only running the same temp because it's cooler is clearing the heat faster).

I give up.... I know what I mean On a brighter note my 970 and 980 have arrived today for reviewing.

Well that's kind of a given isn't it? Reference card running hotter than a custom cooled card? It's also a tangent to the point I was making.
Not really. As I say, the running temperature of the card here is irrelevant. Even if the 780 is expelling heat out the case via the back it's still moving the heat outside the case so the fact the 290 makes the room a lot hotter tells you everything you need to know with regards to the running temp not necessarily being a useful comparison between the two cards which was my point all along.
Exactly.

It's Friday I will admit I'm wrong as I need to have a play with these cards and then visit Xur in Destiny to spend my Strange coins..
I think I'm just not very good at explaining what I mean.
i get what MOOGLEYS is saying.
but nobody can say 2 totally different cards with different coolers on them one runs hotter than the other. if both cards have the same cooler on them and in the same room then yes you could say one runs hotter than the other.

Actually you can very easily, if two things are the same temperature, and one thing has more heat emitting from it, then that thing is producing more heat, it's that simple.
but thats down to the cooler pushing the air
No it isn't. Even if the heat is going out the back of the case it's still outside the case. One way or the other the heat eventually ends up outside the case. One may happen more quickly but the end result is the same.
