I can say 2 of my 980Ti have lower ASIC numbers than the other 2 but the difference in temp under full load is only about 1-2C.  

Has anyone replaced the stock fan on their 980 Ti Hybrid cards and if so, what difference have you seen for idle and load temps? I was thinking of running 1 or 2 (push-pull) of the Scythe AP-14 or AP-15 fans.

You can replace the Hybrid components. Somewhat surprised you bought it if you where going to water cool the rig so soon. No matter. You can purchase any of the Titan X waterblocks from various manufacturers it does not have to be an EVGA block. Have a look on http://www.performance-pcs.com/water-blocks-gpu/shopby/vga-series--titan-x-gtx-980-ti/ 
 
Ive installed my Hybrid on a TITAN X and running on 3 x 3D 1080p monitors (with spanning) and using the 3D Vision the temps are around 62 - 63C compared to 87C

Thanks for the answer and the link. I will look out for an EK Waterblock in Europe (less shipping costs) ;-)

If you are looking for the hybrid cooler for Titan X in the european shop, have a look on:

 
Ooops, just recognized that they ran out of em. Sorry.
 
When is the Full Cover Hydro Copper Waterblock of EVGA for Titan X available in Europe?? Does anybody know?

The Titan X coolers are back in stock from EVGA. Just ordered one.
 
I am currently running a custom fan curve using Afterburner for my stock air cooler. Should I revert back to the stock fan profile before I install the hybrid cooler? 
 
Thanks.

Hey guys, quick question. Where is the pump located? It seems to me the radiator should not be able to fit a pump, but wanted to be sure. Thanks!

Thank you for the confirmation!!!  I was hearing a noise and now I know that it is the fan. I would like to replace but cannot find any information on the specs for the included EVGA fan. Any idea what rpm of the replacement ideally should be?

My install went really smooth this weekend. EVGA's tutorial video on Youtube was very helpful.
 




 
I am so happy with the temps so far.  I went from load temps of 75c @ 70% Fan on air to 42c @ 30% fan with the hybrid cooler.  The system is much more quiet now while gaming, and after about 4 hours of gta5 I did not notice much change in room temp like i was experiencing with the reference blower.
 
 

So I swapped the fan out. Turned out the fan was the culprit that was making the buzzing noise. I chose the EKWB Vardar F2 (1450RPM - PWM) fan. I installed just one pulling from the outside in through the front and my temps are below 50C using unigine heaven benchmark. In hind sight, I would install a fan with up to 2200 RPMs (as you mentioned). But, it works for me.

Have a couple questions regarding installation of these coolers and availability:

1) Need to get two Hybrid coolers for my Titan Xs, but I see they are out of stock.  I see there is a new shroud that just came out, but isn't available for purchase.  Any eta on when the new coolers with the new shrouds will be available and/or the shroud separately?  I know exact dates probably aren't available, but maybe notice if they'll be available before the end of the year?

2) For those that have the Hybrid coolers:

A) Any idea what the heat is like coming from the radiators?  I ask because the Titan Xs run hot as you probably know and right now it's like central heating behind my case where the blower exhaust comes out.  Is there much reduction in the amount of heat thanks in part to the split between the blower fan, the cooler, and the fact that the radiator has a 120mm fan with direct cool air blowing on it from outside (as opposed to a stock card sucking in warmer air from inside the case)?

B) What's the best practice as far as monitoring and regulating the fans on the radiators?  I intend to put them at the front of my case as intakes and then either pushing or pulling through the radiator.  I also intend to use Noctua NF-F12 PWM fans on the radiators and plug those into the motherboard.  I could use Asus Fan Xpert for the radiator fans since it's an Asus motherboard, or Corsair Link since I will also be installing a H110i GTX.  Any experience/recommendations in this area?  What temperature should the fan speeds of the radiators go off of- normally it's the CPU, but I am more concerned with the GPU temps (since with air as I have it now, they get the hottest by far- maybe the situation will be different with the hybrids installed)?  Maybe the PCH since it's right next to the cards- but, I haven't really monitored if it's temp rises in accordance to the card temp?

C) How about the blower fan?  Since the radiator fans are separated, would something like EVGA Precision X/MSI Afterburner be the only way to control the blower?  What type of fan percentage are you guys needing on the blower fan with the Hybrid in stalled?  Is there minimal heat that exhausts out the back of the case?

I set the fan curve 1 to 1 30c ..30% fan
 
my TX's never go over 55c, and that was in the summer time

Hey guys i got a question, i installed my cooler last night and start playing, temperatures really dropped about 30%, but as soon as the chip started to heat the STOCK fan started to go crazy i mean wow the noise was really loud, is this normal ? i mean the card fan its running at 5000rpm !!! and just cant change the speed anyone plz help

Do you mean that the fan on the graphics card itself is running at max speed and you can't lower it? Is it all the time or only when you are playing games? I installed an EVGA Hybrid cooler on my Titan X and everything worked great for a day. The next day the fan on the card was running at full speed and it won't spin down anymore.

Anyone have any guesses as to when titan x coolers available in the US?
Cheers

YESSSSSS THATS MY PROBLEM TOO !!! I CANT Slow it down by any means so im not the only one with this problem ? did u solve it ?? now when i turn on the pc the fan starts at 5000rpm and dont slow down !! its really annoying !

What brand is your Titan X? I believe the EVGA Hybrid causes issues with certain cards. I've tried everything possible and the issue persists. I will now either have to sell my Titan X for cheap or try and RMA it. I lost the receipt so that might not be possible.....

I'm going to call EVGA and see if anything can be done but I have my doubts. They'll probably chalk it up as my Titan X being defective even though I had no issues before installing the Hybrid kit. I've already tried swapping using a new Hybrid kit which of course includes a new pump, checked all the wiring, switched PCI-E slots, reinstalled Windows 10, ran everything at stock speeds, drained my PC of power, reset CMOS, and I've even swapped the PCB heatsink + blower fan on my working Titan X Hybrid to my PNY Titan X and the problem persists! We're not the only people with this problem because I've read user reviews online that have mentioned it. Not many but they are out there
