I have read most of the posts here regarding hybrids, fan speed etc.
My 1080 Ti FTW3 Hybrid will be mounted vertically (MB lying flat), with radiator up top.
Questions :
1. Does the iCX software control fan speed on the radiator, or does it run full speed at all times ?
2. Is the pump situated on the radiator (guessing yes) ?
3. If the pump is on the radiator, would it be possible to swap out the radiator for another pump/radiator combo ? (I know it would probably void warranty..)

You want to rip apart the aio and add your own rad??

Why not just skip it all together and go for something more customizable and reliable and go full water cooling loop and use a ek/d5 pump and res and a ek ftw3 block? Add whatever rad ya want and even add a CPU block and enjoy even better temps?

Have all copper blocks and rad quiet reliable pump!

True enough ;-)
Thing is, I don't feel like putting together a custom loop...would prefer the convenience of AIO.
My plan has been to get a EK-MLC kit for the 7900X.
I know I could add a GPU block to that system, but not sure about the effiency of that "shared" solution.
And I have tons of space for radiators, a pity not to use more of it. Perhaps two separate EK-LC kits would be a solution (but expensive).
 

The block and rad is all aluminum...

Single 120mm fan rad per component in standard clocks.. dual 120 fan rad size for overclocking.. a triple 120mm rad prob would be fine for CPU and GPU. Thick rad 60mm+ better.

The more rad area the slower and quieter you can get away with, with fans.

Personally I went with a dual loop sep system for CPU and GPU with ea using a triple 120mm 60mm thick rad.. I did have 1080 sli at the time though. Now just a single 1080ti ftw3.

With all the issues I see with ftw3 cards and graphic aio setups. I'd be very worry of cutting up a aio on the card and voiding the warranty.

Pump rattle,slow pump death.. yeah I wouldn't touch it.. though at the same time when it works it works good enough to leave it alone.

At any rate... the high entry cost of a full on custom loop isn't that bad when you take in effect that you can reuse the rad, CPU block (most likely) res pump, fans and fittings for years to come on many future builds.. only thing that's a somewhat loss is the GPU block.

Got the space for a quad 120mm rad? Yeah you be all set.

I personally like the ek combo pump/res.. quiet, solid with a known good D5 pump.

I have a 1080ti ftw3 even with one of the new 2000rpm nf-a12x25 noctuas the tiny 120mm rad is easily overwhelmed as soon as you start overclocking the card(low to mid 50s). The Fan on the rad is not controllable and the pump output voltage is too low to spinup the noctuas so you will need to run them off the board. You also cannot control the fan on the vrms unless you use evga precision x oc which cause all kinds of issues on my machines from game crashes to bsods, ended up tearing down the card reapplying the thermal paste and hooking up the vrm fan to the one channel that msi afterburner can control, fairly frankenstein setup. The hybrid setups make sense on the lower TDP cards but with the radiator as small as they are and a 1080ti throwing out some serious heat the value of the hybrid certainly decreases, to the point of me tracking down a ICX cooler to fit to my hybrid card until i fit a real waterblock to it. 

Aha...exactly the problems I feared with the hybrid. So, no Hybrid for me.


Seems wasteful somehow to buy a FTW3 just to rip the fans off of it to install a waterblock. It would also probably void the warranty.
Then again, that route would be cheaper than getting a Hydro Copper (which cannot be found atm anyway). Oh well, maybe the HCs will be back in stock in the foreseeable future, who knows...certainly the most elegant solution  ;-)

Guessing as it's been awhile since I've checked.. 19c on idle and 38-43c max on load. That's overclocked to 2114. Push fans only btw.. corsair sp120 HP. Room temp average at the time of testing was 70-72f. Now it's a cool 64-68 most of the time in the basement durring summer so it would be interesting to check it again.

I'll update in a few hours when I get a chance to run a test.. thinking lower though as I might be getting my numbers confused with my sons ftw3 hybrid cooler.

I think you have a bad temp sensor on your board as it is impossible to be under ambient temps. You said your room temp was 70-72 that's around 21C. 19C is around 66F. So with a room temp 70-72F, you can't have a GPU temp lower unless you're running sub-ambient cooling.

Correct.. As I said was just going off memory from many months ago.
 
Just tested tonight as I had to re install Evga's PXOC.. was a pain to get the OSD setup as they change where the settings are.
 
Idle temp currently at 22C. Room tempt at 68c.  Max temp in firestrike was 31c. Max temp in superposition 8K bench was 34c.. touched it but mostly ran at 32-33c. Mem running at mid to high 20c on idle and low to high 30s during benches. Power idle at upper 20s and mid 30s for one. And mid 30s and low 40s for the one sensor under benches.
 
My sons has the hybrid and its like 10+C higher then my setup.

Icepaw I put an EK full cover on my 1080ti FTW3 - first time tearing a card down and doing it, just follow the instructions - was easy enough. you can also check out you tube videos by JayzTwoCents and GamersNexus as they each should have a video of the process
 
I was able to retain the EVGA backplate - LED works (I have it on Green https://forums.evga.com/FindPost/2829994 )

Tnx. , GGTV-Jon. I'll have to gather the courage and just do it (unless i can find a Hydro Copper).

Lifes short and it's all about the experiance while were here. Just take your time with it and you'll be fine.

Make sure to wrap the old cooler if plastic wrap to keep the old thermal pads safe and clean while in storage. Eventually you'll be putting the old cooler back on when either time to sell/store or rma.

Well said...I'll give it a go !
My 780 Ti DC will be demoted to second fiddle in the near future, methinks. Though it has served me extremely well since December 2013.
 
Tnx to all who replied...you've been very helpful ! 
 

Woe 780ti.. I think ya got your money's worth! Haha. Gonna be a great freaking upgrade there.

Just make sure if this isn't a full on upgrade (where you'll be installing a new windows os) to do yourself a favor and run ddu in safe mode before removing the old card to remove all old nvidia drivers.. so run the remove nvidia drivers and shut down option for upgrade.

Gota be super exciting for you!! Good luck!

Oh yes, the 780 Ti Dual Classified has been fantastic...not ONE problem with it, ever. It has done its job and more, crunching, gaming and everything else. Worth every penny. If the 1080 Ti can live up to that, I'll be a happy camper :-)
I'll be doing an all-new build with a 7900X on a X299 Dark mobo. Planning and pulling together all the pieces atm....will be exciting, for sure...

Please share a pic when done!

I was waiting for a Hydro Copper but when I had the cash to get the GPU it was in the middle of stock shrtages and boosted prices. Gave up on waiting for the higher priced HC and just got the regular FTW3 + EK block
 
And as AHowes said save the stock cooler and all the screws. I put my stock cooler back into the anti static bag the card came in and put it and the screws back into the box just encase I have an issue in the next 3 years :P

You can control the radiator fan if you are willing to remove the gpu shroud. The gpu fan header on the pcb is not being used on the Hybrid.
 
Here is a picture of the PCB of the FTW3. A FTW3 Hybrid should be identical.

 
 
This connector is for the gpu radiator fan.(Fan 1 GPU) It is empty on a FTW3 Hybrid. Just plug this connector into the 4 pin header on the pcb and plug the other end into the radiator fan. You can control this fan with Precision or Afterburner based on gpu temperature.

I connect a 4 pin y connector to the above cable to run two Noctua's in push/pull on the radiator. Works well.
