I decided to try this before going for a custom water cooling loop, plus full cover blocks for these cards aren't out yet.
 
Here's what someone looking to do this may run into:
 
1. The fan on the G10 bracket blows air over the right side of the GPU, the VRM's are on the left side of the GPU. So I removed the thermal pad from the ACX cooler covering the VRM's and placed it onto the VRM's. Then I mounted some heatsinks I had on hand to the VRM's.
 
2. When installing the PCI-E power connectors, the space between the G10 bracket and the 970 is limited. Installing the connectors is fine but to push the latches down to remove the connectors may prove challenging since the latches are really close to the G10 bracket.
 
3. NZXT branding in my mostly Corsair system, lol, not really an issue.
 
As for the H90, I am using a Corsair SP140 fan in push, I am not using the provided 140mm fan.
 
Planning to do some testing and I will update this post in the next day or two.
 
I can say this, idle temps are lower and a quick run thru the Heaven benchmark shows about 20 degree lower temps vs. the ACX 2.0 cooler at 40-50% fan speed at full load, while remaining nearly silent!
 

 
 

Woukd this fit the blower type 970?

Finally got around to testing this setup.
 
Test system:
 
Corsair 730T Case - (2) AF140L Intake, (1) AF120 Intake
Intel I5 4690K CPU @ 4.5ghz - 1.185V - Corsair H110 Cooler - SP140 fans in push
Asus Maximus Hero VII Motherboard
Corsair Vengeance 2400mhz RAM 2x8 GB Kit
EVGA GTX 970 SC
Crucial M4 64 GB SSD - OS Drive
Samsung 840 Pro 120 GB SSD - Media Drive
Samsung 850 EVO 500 GB - Game drive
Corsair HX750 PSU
 
Heaven Benchmark
Quality - Ultra
Tesselation - Extreme
Anti-Aliasing - x8
 
GTX 970 SC ACX 2.0 Cooler
Boost Clock - 1342mhz (stock)
Power target - 100%
 
Fan Speed - 30% - Max Temp 68 degrees
Fan Speed - 40% - Max Temp 62 degrees
Fan Speed - 50% - Max Temp 59 degrees
 
GTX 970 SC ACX 2.0 Cooler
Boost Clock - 1501mhz (+25mv)
Memory Clock - 3600mhz
Power target - 110%
 
Fan Speed - 30% - Max Temp 71 degrees
Fan Speed - 40% - Max Temp 64 degrees
Fan Speed - 50% - Max Temp 61 degrees
 
GTX 970 SC - Kraken G10 - Corsair H90 Cooler - SP140 fan in push
Boost Clock - 1342mhz (stock)
Power target - 100%
 
Max Temp - 44 degrees
 
GTX 970 SC - Kraken G10 - Corsair H90 Cooler - SP140 fan in push
Boost Clock - 1501mhz (+25mv)
Memory Clock - 3600mhz
Power target - 110%
 
Max Temp - 45 degrees
 
So basically there is a 15-26 degree drop when cooling with the G10/H90 combination versus the ACX 2.0 cooler. However, the real benefit is the noise reduction. The ACX 2.0 fans on 40-50% especially when running in SLI are annoyingly loud. This setup is quiet!
 
Btw my ACX 2.0 cooler was only touching 2 of the 3 heatpipes, its a known issue, just thought I would add that.

Can you do a "bar" type heatsink across all the VRM with tape or thermal adhesive or the small individual ones? I ask in regard to like shorting anything out.

Also, is there anything else that I should put heatsinks on? I'm running the same as you with sli and krackens 

Thanks!

I am looking to do this as well on my 970 SC ACX 2.0 cards.
 
How much space do you need between the cards? I have the MSI Xpower AC X99S board, so there are about 3 full PCIe slots between my 2 16x slots, hoping that is enough to put two of these in.

You can do a bar type heatsink, I used the factory thermal pad and individual heatsinks. Just cuz thats what I had.

how were you able to get the H90 to work with the G10?
 
EDIT: I know where the Pump connector goes, but where does the connector for the G10 and the H90 fans goes to?

The biggest problem with an AIO is that it doesn't actively cool the VRM and the VRAM with the coolant.  It still relies on air to cool those.....you'll get some decent clocks out of the core, but, the memory will still suffer, as will the VRM if you start pumping more volts through it.  /shrug

can you help me with a problem I am having right now?

With where to put the wires in?  No....

how come?
