Okay Jumping back into Water cooling after being out of it for 8 years looking for Loop advice
I have two top mounted 480's and a Bottom mounted 360, bay resevore and dual pumps(EK Dual DDC 3.2 PWM X-TOP w/ Pumps (EK-Dual DDC 3.2 PWM X-TOP ) in series

Items to be cooled are dual GTX 780's CPU and MB

I have the Asus Forumla VI (built in water cooling for the MB) both Video cards have the blocks installed and I picked up a CPU block from frozencpu.com some people say you are dumping hot water into the next block but each bit of water removed a bit of heat so I think any of the options below are fine but #2 and #3 are far more complex to set up.


First option

480(1) to 480(2) to CPU to MB to Video(1) to Video(2) to 360(1) to Pump to 480(1)

Second Option
480(1) to 480(2) to CPU to MB to 360(1) to Video(1) to Video(2) to pump to 480(1)

Third option
480(1) to CPU to MB to 480(2) to Video(1) to 360 to Video(2) to Pump to 480(1)

That's a pretty complex loop, you might consider running dual loops, but you could also run a single loop with more pump redundancy. Loop order isn't really pertinent in any loop as the temps equalize and will run within a few degrees C in different places in the loop as long as you have your delta and flow in good order.

Any of your loop orders above will perform well, although if you want the coolest temps on your cards, you'll want option 2 or 3, with option 3 giving you the layout of a radiator between each heat producer. Your temps could be 1-2C cooler with this, but overall and that much radiator space, I don't foresee temp issues being a problem given you have enough flow and head to push that loop.

Again, I would recommend dual loops (CPU+MB on the 360) and the two graphics cards on the other...and you could almost get rid of one of the 480's given you run good fans (1500rpm, good static pressure) on the one.

My option would be:

Reservoir > Pump 1 (D655) > Motherboard > Radiator 1 (3x120mm) > pump 2 (optional 355x) > GPU 1 > GPU 2 > Radiator 2 (3x120mm)

My 2 cents

The order of your components doesn't make any difference. The ONLY thing you need to have is the reservoir before your pump so your pump will never run dry. Run your loops in the cleanest, most direct route through your case.

It isn't a requirement...the only requirement is that the pump doesn't run dry. It just makes it simpler if the reservoir precedes the pump, but it still needs maintain a water level above the pump inlet.
