My experience with the 690 hydrocopper hasn't been all that stellar due to many reasons but once I got my hands on a good gtx 690 and a hydrocopper on that card, its one hell of a combination.
 
First off, a couple pictures of the product. 
 



 
 
With the waterblock on the 690, I was able to push the card to a offset of +180mhz at a power setting of +134%
 

 
This gives a final clock of a healthy 1228mhz. That's quite an overclock for a dual graphics card. Sure its no 1300+ like the 680 classys but hey I've got two of these things on one PCB.
 
First up, unigine 1920x1200 max everything.

 
With AA, Tessellation, and Anisotropy set to maximum, I was able to get an average of 87.9 fps.
After looping for about 30 minutes, my card topped out around 44-45C. I'm running a RX360, 60mm radiator, with a overclocked 2700K @ 5.0 Ghz in the loop. Sure 45C is slightly higher than what most people are getting but I'm also pumping in 1.485V into the CPU. Not to mention, the ambient temperature is 78F
 
The card idles around 28-29C.
 
For comparison, I ran Unigine at completely default 1080p again and came up with a score of 4925.

 
 
Next 3Dmark11. I've only got the basic edition right now so all I can do is the performance run.
I've got a P score of 16560

If anyone wants to give me a 3dmark11 advanced key, I can run an extreme test as well. :)
 
 
 

Doh! I totally forgot about the memory
 
Acutally, I can't seem to hit 1700.
 
With a +180  core offset and a 700 memory offset I still top out at 16722

Maybe it's the 2700K's Hyperthreading?
