Hey guys, I'm planning my next build with x99 right around the corner and need some input. I have a corsair 900D case with 2 480's and a 240mm rad and I'm wanting to know at what point 2 D5's would start to be needed, I would like the ability to cool 4GPU's,CPU,Mobo,etc with several 90 degree fittings and 3/8 x 1/2 tubing. Now with that said starting out I will only be cooling 2 GPU's and the CPU and I would think a single D5 could handle that. But as time goes on I'd like the option of expanding the loop without replacing the pump. Should I go ahead and buy a dual pump combo now, or will a single D5 handle everything I'll be throwing at it?

Cooling that much is going to take a large surface area to pull heat away. I currently run a 4770k and 3 GPUs, and it gets warm, and I have a lot of radiator surface area. I would suggest 2 pumps, so that you can run the cpu and motherboard parts separate from the GPUs.
Running 2 loops is going to allow the heat to be dissipated much more efficiently. And will also not allow the hest of the cpu to dump extra hest into the loop and cause a possible overheating issue in total.

According to everything I've read dual loops make a negligible difference, although that could only be the case for small loops and the more you try to cool the more dual loops start to have an advantage possibly?

I know running my cpu, it is currently running 45-50c. Add one gpu, it goes up a few c, to 53c or so... Then 2 goes up to 60c... 3 up to 70c.. That isn't negligible if you ask me.

How much rad are you running, just out of curiosity?

1 - 120mm: exhaust
1 - 280mm: exhaust
1 - 280mm: intake
1 - 240mm: intake
I also run dual pumps, because with a single pump, there was always an air bubble in the top rad that caused microbubbles. After installing the second pump, the microbubbles were gone in a couple of hours.

Nice, I think I'm gonna go ahead opt for a second pump but hold off on the dual loops just because I don't have the hardware that calls for it right now. It's just a CPU and 2 GPU's at the moment.

Just the cpu and 2 GPUs will be perfectly fine. Just think, each new components needs approximately 120mm of cooling space. I am switch the exhaust 280 out for a 360mm and going to look into going with dual loops as well.

It is negligible if you are doing CPU on one, and 2 way SLI on the other. If you have lots of case space it can make things easier for maintenance, but for bigger loops dual and 2 pumps is a really good idea. Also, 480s produce a LOT of heat as well as most of the blocks have a bit of restriction, I have seen a similar loop to that done, and after a while on a single pump, temps were much warmer and the impeller on the pump was toasted, a loop that size REALLY needs 2 pumps, and using 2 loops would make things easier too, and cooler.

IMO Single loop with dual D5 is appropriate for your proposed system. If for no other reason than redundancy it's a great idea. Also with 2 pumps both will work less hard. Separate the pumps to boost head pressure and increase flow rate best. Say your pump 1 is at the beginning of the loop place the 2nd in the middle of the loop preferably 1 before and 2 after the waterblocks which are the most restrictive to help pick back up the pressure and flow. Dual Pump tops are sweet for saving space but I'd argue it's more efficient the way I propose. Eliminate as many 90s as you can. For an alternative many times a swivel 45 are usable and slightly less restrictive especially when using flexible tubing. GL

I hope to put separate GPU loop in by the end of the year. I am not sure if my loop can handle another device. Scarlet-tech is right about the bubbles. Before I added my second rad and VRM block, my bubbles would be gone within a couple of hours. With 2 Rads and 3 blocks, it took a week for the bubbles to get free and I had to do a lot of moving my case around. Moving a 900D full of water is not easy, :/. I think this means that I might be close to my max number of devices to push water through on one pump.

I would try one, then add a second if you are not happy with the performance.

Ownscraftsman is definitely correct, it will help, necessary, I doubt it but possible.
In your place I would do what RainStryke recommended. You can always add in another one.
I have thought about adding in a secondary on both of my loops, but really, the challenge is mounting it, as I would do it inline.
