When should I split to two loops?

post #1 of 4
Thread Starter 
I am working on compiling my list of parts for a new build and so far I have the plan to build in the Corsair 600T

Here are my list of parts so far

3 x 120mm Radiator (Up top)
200mm Radiator (Up front)
EK-X99 Monoblock
EK-XTOP Revo D5
EK 780ti Classy Blocks X 2
Aqua Computer M.2 SSD Blocks X2


I was wondering how do I know when I should separate the 6950X CPU block from the GPU/SSD's?

Dual loop is for the looks. If you like the looks of it, go for it.

I don't agree that dual loops are for looks.

In more complicated setups dual loop or triple loop is viable choice (if you have the space). It simplifies maintenance greatly, it simplifies emergency repairs even more (take Maxwell for example, you can easily replace parts of loops leaving card without coolant while working in 2D). Granted if you have only CPU+VGA combo it doesn't make any sense. But if you running multiple heavily loaded VGAs or RAID cards separating loops is good idea. Less heat dumped into one common circulation.

Take it from me. I don't use multiple VGAs, but I have multiple RAID controllers. CPU alone does not require frequent maintenance, but with few hot chips as found in controllers I can perform easy, more frequent maintenance on storage subsystem without need to drain and bleed CPU loop. Basically doing kind of "hot-swap" coolant change on only some part instead powering it down completely.

Pretty much two main questions are (assuming that cost is not an issue):

1. Is it really required?
2. Is there enough space to accommodate everything?

For your small setup it's too much hassle. In particular when you cannot drain 100% of coolant from monoblock part anyway so advantage of easy maintenance is nullified... IMHO NVMe waterblocks are total overkill. While 950Pros (guessing) controller gets really hot (60-70C) memory dies are reasonably cool (about 30C or even less at the opposite end). Passive radiator is all you need. And in case when you want to change SSD you don't have to drain the loop... but it's only me rambling about. biggrin.gif

You want it. Then do it. thumb.gif

Hmm... interesting

I was debating that myself a moment ago, thinking it was probably more efficient to dissipate heat having one loop for CPU, and another loop for dual SLI video cards.

most of the time CPU once installed it remains there forever

but video cards ... we change it as often as we change underwear , basically whenever a new more powerful ones gets released.

having 2 separate loop makes maintenance simpler and only affects the specific loop you are working on, also heat wise it will go into separate Radiators, most of the heat now in days are generated by the Video cards.

I understand single loop is by default on most setup, as the PC cases are usually small and cramped, not enough space to install additional loops, unless you are running a custom case with lots of spaces.
