I'm oc'd +200mhz and my temp goes from like 33* to 50* so I'd have to say something isn't right; some adjustments are in order perhaps.

What thermal paste did you use, or did you just use the stock pad? I replaced the pad with some old paste I've had for years, which took a day or more to cure and I did see the temps come down a couple degrees thereafter. I also installed a 2nd 120mm fan, which of course dropped the temps further.

Pics man, where are your pics! :]

74 is too high on the kelper cards, you want to stay below 69. Also, 74C is incredibly hot on a watercooled kepler card. People manage to stay below 69 on reference air coolers.

Sure looks like the exact same PCB.

so far my idle temp is 37*c and ive hit 72 in kombuster (the one in after burner). Afterburner is telling me my min temp was 30 and my max was 74.

this seems a bit hot and the tubes and rad are COOKING hot, any tips? should i lap this thing and try and re seat? less tim or more?

In a lot of the photos I've seen here, I'm totally blown away by how much TIM/paste people use; I use, literally 50% less than most people. Rice sized? Not even... and I don't just plop the cooler down either ...

Personally, I put *only* enough TIM/paste as is necessary so that I can, with a razor blade or even a credit card, slowly spread it, very thin across the entire GPU surface. I've always done my GPU's this way and I've never had to re seat due to temps.

That said, if your using a very slow fan then maybe a GTX580 could hit 74 but I would think there's a mount problem of some kind for a 680 to get that hot. Even on completely silent fan settings, my 670 never hits 74, much less 64 ... I top out about 57C in Furmark and Kumbuster at silent fan settings, even lower at audible fan settings.

Try a super thinly spread layer of paste (use a credit card or the like and press/spread it very thin. Start with a half rice sized grain, that should be enough if you take your time and rotate the card, spreading slowly to each edge.

Or, just try a smaller drop in the middle. As I see it, after mounting (and later removing your cooler) there should never be any compound pressed off the edges of the die/heat spreader so that it overflows onto any of the surrounding surfaces/components ... I use that as a benchmark for whether I've applied the appropriate amount of paste.

Good luck ...

If you spread the TIM, you have more change of air bubbles underneath.
On 1:50 you can see that if you apply pressure, air bubbles form. But it depends on the TIM offcourse.

And just to be clear about Asetek 760GC:

I used 2 760GC's

I did not use CPU pumps on GPU's

Each 760GC was put on one CPU and one GPU

The hoses come out of CPU's vertically and GPU's horizontally. Though, the CPU hoses can be rotated some.

If you had multiple GPU's in close proximity, I am not sure you could use both pump/coldplates on your GPU's...
unless someone has made this work.. please speak up if you have. I am sure there are many a dude here who
could possibly be interested in 760GC for two GPU's... either way, Asetek needs to get busy making 2 GPU
versions of 760... my next build will have 4 GPU's in 8 slots... to watercool these with CLC's, I am going to need
those hoses sticking out the sides...

I suppose that in a two card setup, the CPU hoses would not make much difference - so long as you put them
in the right order so that CPU hoses were not mashing into other GPU...

Mind measuring the hoses on those 760GC's?
