Questions For Cooling Two Titans/GTX 780

post #1 of 4
Thread Starter 
I'm planning on running a PC with two Titans or 780 liquid cooled graphics cards from EVGA. I already have a separate Intel liquid cooler for the processor, and would like to supply each graphics card with cool water. I have a couple of questions on how this could work.

1. Could I use two of these and cut the tubing to the CPU cooler, then route the tubes into the graphics cards? http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=7750582&CatId=499

2. Could I route the hot vented water to a radiator from the first card then to the second card then to a second radiator using one pump and water tank?

3. What is the best coolants to use that does not conduct electricity?

Thanks for now. I'm sure will have more questions as this will be my first venture into water cooling. (Other than processors.)

I think your best bet would be to do some research and head down the custom loop path. Will perform better than cutting up other coolers and trying to make them work together. Take your time to find out everything you need first though.

That sounds like good advice. So what about question 2? Can I create a custom loop that includes a second radiator between the two cards and use one pump and res. Or should I have a complete loop for each card (two radiators pumps and res)?

You can link many things together in a watercooling loop just fine, so long you have enough rad space. Most common advise is 120mm rad space per component, plus an additional 120mm. So for your CPU and 2 GPU's in 1 loop, you should consider a total of 4x120mm radiator space. You can always have more and then you don't have to run fans as fast since there is more surface area to cool the loop with.

Check out the watercooling section. You can get a good start there and get any help if you have questions. http://www.overclock.net/f/61/water-cooling
