hey i've noticed that the hydro copper has a wide bridge (think that's what its called) where the inlet and outlet are  while every other EK block has a more narrow bridge. why is that?   is there any difference from the titanx block and the hydro copper block other than the evga logo on the top of the block?  

All HydroCopper have a proprietary bridge instead of the standard EK bridge.  EVGA wanted this bridge design to have extra ports on top of the bridge and the lighting effect on it.

OK, EK Tech Support answered.  They simply said, don't use them.  I think I will get some anyway.  I think there will be a slight advantage to cooling the pcb on the backside of the ram chips.

Dear John
 
Thank you for contacting us.
 
No, you won't need them because if it doesn't have vram chips on the back of the PCB than you don't have anything to cool there. You can than use your backplate without those thermal pads.
 
Best regards, Igor

Good!!  
 
From what I can imagine, you could add a 1mm thickness in terms of thermal pads to compensate the lack of RAM chips.

 Figured I'd ask here since you'd know best. I'm wanting to use the Step-Up program to get a GTX 980Ti, however the only one being offered under the step-up program is the EVGA GeForce GTX 980 Ti ACX 2.0+...(06G-P4-4991-KR).....is the EK Titan full waterblock compatible with this card or is the pcb layout different? Thanks in advance

If you meant Titan X waterblock then yes it will. All the cards currently listed on the EVGA website are reference boards.

The ACX 2.0+ aren't listed in our compatibility list for the Titan X waterblock.  We would need a confirmation from an EVGA rep to know if they changed the PCB layout or just the aircooler.

Originally there was suppose to be a 980Ti block but since the Titan X waterblock is compatible, it will be used has the official waterblock for the 980Ti. 

Are you saying that the EK Titan X Fullcover Water Block will fit or work on all of the EVGA GTX 980Ti Graphics Card Models?

So far, the 06G-P4-4990-KR and the 06G-P4-4992-KR are listed as compatible with the Titant X block and for the 2.0+ models we would need a confirmation from an EVGA rep to know if the PCB as been changed or not.  If it hasn't been changed then the 06G-P4-4991-KR, 06G-P4-4993-KR and 06G-P4-4995-KR would as well be compatible.

So, just to be clear, you identified EVGA 980tis as compatible with your wateblocks based purely on the looks, i.e. which ones have reference cooler and which don't, right? Because you don't really have any of them (EVGA-branded cards) back in Slovenia to physically check compatibility with your TitanX blocks?

Thanks for the update Luc,
I will wait until the end of the summer to re-review what is available.
