I would love to know about experiences with liquid cooling, especially for 4 cards.
Looks like EVGA sells a card with a cooling block, but not a cooling block itself....
Thanks !

Alright... Four Titan Blacks here, water cooled. What would you like to know? ;)

Ek makes some great blocks. They are the same blocks, minus the evga logo, that the 900 hydro copper cards will have. :-) sitting on 3 780ti Classified with EK blocks. Their instruction manuals and everything are pretty awesome. I do not have experience with other companies though.

I'd love to know what brands you used... How well do they integrate with cpu water cooling ?
What power are you using for the cards ? 1600 watt ?
@scarlet-tech
It sounds others had problems with the EK ?
Also, same question as above, How well do they integrate with cpu water cooling ?
@scarlblat
Do you recommend the EK ? So you need to switch out the screws ?
Since I need to go liquid with 4 x 780, it seems I may as well go liquid with my dual procs too...
Thanks for the advice !!

XSPC Razor waterblocks: http://www.xs-pc.com/waterblocks-gpu/razor-gtx-titan-780-780ti CPU is air cooled... unusual, I know. :) Main reason for this is that I actually ran out of radiator space. My case is Fractal Design Arc XL which is not very roomy for this kind of setup. I am using Alphacool ST30 radiators - one 120x3, one 120x2, and one 120x1, for a total of six 120 mm sections. I'd actually suggest going with twice as much, but since I've already built my rig, I am going to run it like that for a while. Other than that, integrating CPU waterblock into the loop would have probably been pretty straightforward - just a few more fittings and pieces of tube. PSU is Corsair AX1500i.

I have three 780 Ti's all with EK Waterblocks and backplates. I have had none of the issues anyone has mentioned. Mine were installed in December of 2013. I have all EK blocks in my rig. Motherboard, RAM, and CPU. All work flawlessly. The two 480mm radiators I have are also EK PE radiators. I also have two Corsair AX860 PSUs powering the system. Never had an issue with anything. Current CPU is i7 4930K, which will be changed to an i7 4960X when I drain my loop here over the next week, which is drain number 2. I will use only EK blocks based on the performance I have gotten over this past year with this rig. Just my two cents.

Back plates are not allways usefull. But they protect the exposed side of the PCB, and they can add some cooling when RAM sits on this side. They give a neat aspect : they make your video card look like a Pentium II.
Very important : choose reference design cards (radial blower) if you want full cover blocks, and verify compatibility before you purchase video cards !

I didn't buy reference... I got the ACX cooler design GTX 780's... Does that mean I should not buy full cover ? Looks like EVGA europe sells 780 water blocks http://eu.evga.com/produc....asp?pn=400-CU-G780-B2 On the EK water block site there is a choice of Acetal or Nickel or regular, whats the difference ? Also, what extra kit do I need, this **** looks crazee ???!!! - universal CPU water block: EK-Supremacy Clean CSQ (incl. LED diode, mounting- & thermal material) - radiator: EK-CoolStream RAD XTX 240 (Double) - radiator fan: EK-FAN Silent 120-1600 RPM (2pcs) - water pump: EK-DDC 3.2 PWM Elite Edition (incl. pump holders) - reservoir: EK-RES X3 150 - tubing: PrimoChill PrimoFlex™ Advanced LRT™ 13/10mm (2 meters) - compression fittings: EK-CSQ Fitting 13/10mm - G1/4 Nickel (8 pcs) - coolant concentrate:EK-Ekoolant EVO Clear (100mL; for 1L of coolant) - Y-cable splitter: EK-Cable Y-Splitter 2-Fan PWM (10cm) - ATX bridging plug

the 780acx (like the 780ti acx) are all reference pcbs as far as i know! theres no problem watercooling them! only the classified and kingkin versions use custom pcb designs!

Fine. Did that to find lower cost back-up batteries. I just bought one that has 1600W, but it was expensive, as I will change to one PSU since I am build two other rigs and will use my Corsair AX860's in each of those. They are both Corsair AX860. I like the back plates. They are not necessary but provide a clean look for the GPU, IMO. They also help in the reduction of heat related to any items on the back of the board. Although the water loop does not run through them, they can cool with the air flow from the case if that is good. I only buy reference because I water cool all my GPUs. I do not like paying for or removing the ACX coolers of other types of coolers there are on the many card variants out there. I like the Acetal Nickel blocks, but cooper does a great job of heat transfer. If you want to use colored water or light up your rig, then the plexy will allow you this option with an neon water cooler and black light rig, for instance. Acetal is the front compound used, Nickel is the metal used to transfer the GPU and VRAM heat exchange with the water. That looks nice, but think about the flow or the loop. I always say you go from reservoir to CPU and motherboard to radiator to GPUs then to radiator then back to reservoir and pump. Each opinion is different. PM me if you want to go through it and see what plans you have. Always willing to help. Always verify compatibilioty before buying the blocks you want. Call the company or call the reseller to assure you are getting the right equipment. E-mails are also nice, as they create paper trails. Hope this helps.

There are many opinions here. Just remember that you do not want to have a hotter item like a GPU before your CPU in a loop, in my opinion. Most go RES-CPU-RAD-GPU-RAD-RES. The common rule of thumb is 120mm of radiator space for each block on the loop. I would use a 240mm today for most CPU only loops. Just because that is how I feel, as if you overclock at you will need it. If no overclock 120mm is fine. I have my RAM, CPU, X79 chip and MOSFET (motherboard) on one loop with a 480mm radiator. I have my three 780 Ti's on another loop with a 480mm radiator. I personally do not like to mix CPU and GPU in water loops, my preference. With the correct water flow and correct water pressure, there is very little difference, say 2-3 degrees Celsius, but I just do my rigs that way. Do some Google searches and review some videos by Linus Tech tips and others on YouTube. Seeing it in a video is much better than reading it, in my opinion. Research and thought are your best friend in this. This is not just throw a bunch of blocks, tie them together with tubing, hook it up to a radiator, reservoir and pump and your done. Much more complex then that. Not heart or brain surgery, just gain some knowledge and think it through. Thought and planning are always your best friend in things like this.

Grey_Beard, I split my PSU into two for the same reason. With 3 GPU's installed it was causing me big power issues. I use One PSU for the MB and all Hardware like Hard Drives, Fans, DVD, Water Pumps, and so on and One PSU only for the GPU's. This is the cable that I use: Length: 33cm / 13in - 18AWG Wires  Vantacor Dual PSU Adapter Cable 24 Pin 2-way $9.99 Prime. Now Testing with 3 PSU and the below cable.  Vantacor Triple PSU Adapter Cable 24 Pin 3-way $11.99 Prime

for example I read this:
"If it is not grounded to the frame you will want to make sure the ground on the two 24 pin connector are spliced together. You definitely do not want to create a ground loop in your system by combining non-referenced PSU's together. This can cause noise and even fry components in a worse case."

On both current rigs that have two PSU installed one PSU is mounted in the case the other siting on the Wire Rack. I have been running this way for over 2 years now. On my 3rd rig I have both PSU mounted it the case.
