1 or 2 or even 3 Loops with so many components?

post #1 of 5
Thread Starter 
I'm trying to come up with a plan here and I could use some suggestions and opinions.

Here's the plan so far, nothing really set in stone.

Water cooling the CPU, mobo, ram, and 2 GPU's. ( might do HDD cooling as well because I can.)

With 6~9 water blocks, res, and at least a 9x120 radiator will a single pump run it? or is 2 or even 3 loops a better option?

It is possible with one D5 pump on the highest setting. But if you care about noise you should go with two D5 pumps. One loop for MB, Ram, HDD and CPU and one for the GPU"s.

But cooling HDD, Ram and Mainboard with water is really a big waste of money.

More loops are almost never a better option. You lose redundancy you would have had if you ran everything on a single loop but with multiple pumps in serial, and usually your components end up not being cooled as well in a multi-loop config as with a single loop. For example, my rig has two 360mm rads and a dual bay res with two D5's pumping the coolant through the cpu and two GPUs. If I was to split this into two loops, say one rad for the CPU and one rad for the two GPUs, i'd be in a position where the single RX360 rad may be happy to deal with the two GTX 580s, but the single RX360 rad for the CPU is totally overkill and is largely a waste. Having all components on a single, bigger loop means a larger volume of water per loop (= more capacity to carry heat away from your chips) the possibility of redundancy (if you run two pumps in it in serial, if one dies you're still good to go until you can replace the broken pump) and of course less parts, less tedious maintenance.

As a rough comparison I'm running a single loop with 7 blocks and 3 quad rads.

 

With a single 35X I get 0.6gpm at full speed (4440rpm), 0.3gpm at 3500rpm, unmeasurable at 1500rpm.

 

With a 35X2 I get 1.0gpm with them at 4440rpm, 0.7gpm at 3500rpm, 0.15gpm at 1500rpm.

 

With a 35X2 and 35X I get 1.3gpm at 4440rpm, 1.0gpm at 3500rpm and 0.3gpm at 1500rpm

 

Even a single pump at 3500rpm (0.3gpm) gives enough flow for decent CPU temps and with triple pumps I aim for around 0.6gpm with the pumps at 2400rpm for very low noise levels.

Yeah I just found the stuff to put 2 655s in series. I didn't know such a beast existed.

My limited understanding of thermodynamics made me want to run everything in one big ass loop, but I was worried a single 655 or d5 is what they call them now couldn't run such a large loop.
