Got mine last night. Installed like a breeze. In a 17 r3 with 6820HK. 15,000 firestrike score right out the box stock settings on gpu and cpu.
 
 

Can you tell me why you cant control the fan speed of the radiator fan?

Can you tell me why you cant control the fan speed of the radiator fan?

Ultimately, a very poor decision made by the EVGA engineers.  They should have used a PWM (4-pin) fan solution, but instead chose to use a 'backyard special' Frankenstein 2-pin to 3-pin cable; 2-pin portion connects to the radiator fan and the 3-pin end is connected to a Y connector cable off of the graphics card's PCB, which is not visible because it is underneath the graphic card's shroud.  You will have to remove the shroud to access the 3-pin end coming off the Y connector cable.  That Y connector also provides power to the pump I believe (can't remember for sure, but it is providing power to the pump -or- the blower fan).  A lot of complaints about this design flaw.  The only real feasible solution is to replace the stock fan with an aftermarket 3rd party 120mm PWM fan and plug it into the motherboard and create a custom fan curve based.  To fair to EVGA, I had to do this with my MSI Seahawk X GTX1080Ti (hybrid) card as it to came with a non-PWM radiator fan.  I used this method and also chose to use a 2-pin Temp sensor to directly monitor the GPU radiator exhaust temperature.  I then created the custom fan curve based off of those temps at idle and full load.  Works great - both GPU temps and fan noise are kept to a minimum unless I am torture testing/heavy benchmarking the GPU.

Nexus has recommended a second solution, but is more involved to implement and requires that you buy a special VGA power adapter cable that allows for you to use the PWM fan connector on the graphics card PCB to a 4-pin PWM fan.  The PWM fan connector on the graphics card is NOT like the ones you see on your motherboard, so this is the reason why the special adapter cable is required.  Again, a reminder to use this solution it will require the disassembly of the graphics card's shroud in order to get full access to and replace that 2-pin to 3-pin power cable.  This solution would allow for you to directly control both the blower fan and the radiator fan using a single fan curve.  Here's a link to the special VGA power cable adapter that you can purchase on Amazon.com:

Good luck with whatever solution you decide to use!

SC2 is built on the stock Nvidia FE PCB which only has 1 fan controller which is used for the VRM/Memory fan. There isn't another Controller on it to manage the radiator fan/pump which is why they are split off it 2 wire without control since the only other power plug is only for a LED and cannot power anything else

If you wanted control you need to wait for a custom PCB hybrid like a FTW3 hybrid for example. That card that has 3 fan controllers on it and I expect separate control for pump/radiator fan/vrm fan all independent.

The SC2 is basically the FE board but with ICX sensors. Gamersnexus has a photo of the SC2 (aircooled) taken apart and the PCB, power phases, and components are identical to the FE. Not that it is a bad thing as the FE board is pretty good, but that is what it is.
 
Regarding fan control, I just disconnected the stock fan, added my own SP fans and plugged them into the fan controller on my case. I have three options to choose from compared to stock, nearly silent but a little warmer, same noise level but a little cooler, or louder and much cooler. I tend to run the quiet setting most of the time. Very easy for me to control the fan speeds now. 

I looked again and yes, they are not 100% identical. However the SC2 has a lot of similarities with the FE board. There are minor differences but they are largely the same. I believe the SC2 is mild customization of the FE board and not fully custom. I agree with your earlier assessment that its an 'upscale' version of the FE.
 
Here is the FE, SC2, and FTW3 for comparison.

I also have the option to plug a PWM fan into my motherboard and control it that way too but in my experience the external fan controller has been an ideal solution. I can easily control the temps and noise even mid game without having to adjust a fan curve. I also did not have to buy any additional sensors or cables as my case already had this built in. I'm glad your solution works well for you but I have also been very satisfied with mine. 
 

Yes, there are multiple ways to control the radiator fan. Depending on what equipment someone already has a certain solution may work better for them. My case has made it very easy for me to control the fan so I went that route and so far the experience has been very positive. I like it as it is pretty hands off, I usually just leave it in the quiet setting and temps are well under control. It is easy to turn up but I haven't needed to other than just to play with it. However if someone doesn't have the equipment already, they have options like yours where they have more control over the temps/noise using a custom fan curve. This requires more work but they can tailor it to what they want to do.
 
Either way, I think they're a big upgrade over the stock fan which runs 100% of the time which got pretty noisy even when the computer was idle.

Noctua NF-F12-PWM, 1500RPM is good enough for me and it stays pretty quiet :)

While not as quiet the stock EVGA fan cools the hybrid radiator 5 degrees better than that fan. I've tested with two separate of that exact fan model @100%fan speed. 1500rpm just can't compete with 2200rpm. I've thought about ordering a industrial version with higher rpm to test.

Well, of course 2,2k RPM kept it in better temperatures, but my #1 priority while ordering such card was quietness. I actually run it at 1,2k RPM with Noctua. Idle at 30 degrees, under load 55-60 max with steady boost of 2,000Mhz on core. Pretty damn happy. Pretty interesting stuff about other solutions in this thread, though! :)

Hi. Unfortunately, I'm using an eGPU, so I have no access to a motherboard or case. So, Nexus' solution really intrigues me. Can you link me to where we he posts about this? Thanks!
 

Wish I would've been patient enough... When I was on the market for a 1080ti I initially wanted to get the Hybrid, but me being the impatient bastard I am and have been thinking about doing a full hardline custom loop.... I just went with the 1080ti FE and ended up spending about $900~ on watercooling components.
 
After owning a 1070 FTW Hybrid I just couldn't see myself ever using air to cool my graphics card ever again. I loved that 1070, and it was a silicon lottery winner too from what I've been told... The little guy had a more than stable OC @ 2164mhz on the core clock with a +175 offset, and I don't remember the numbers for the memory but I was running a +400 offset.

Finally received mine yeasterday.

Congratulations
I still am waiting

Finally installed my card today.
 
I have replaced the fan with an NZXT AER. The cards dimensions are a perfect fit for what I had planned on my build. 
 

 
 

Was the fan replacement just for aesthetics or did it improve thermal performance?
 
I tried swapping out the stock fan for a Corsair Mag Lev 120 but it spun really slowly off the lead wire. I rerouted it for power and it spun faster, but the stock fan was still more effective on thermals. I'm wondering if another fan might improve on the standard system.
