Dual Loop Vs Single loop

[samuelellis]

Just a quick question

 

Does having your CPU and GPU(s) on seperate cooling loops actually do anything beneficial or is it just because dual loops are pretty cool when running two different colours of cooland?

It can lower temps, but only if done right. I wouldn't bother unless you have enough money for 2 loops, enough case space, and know what you're doing.

2 loops equal twice the space of a single loop or dual loop minus a reservoir and radiator (maybe the pump as well). It could be easier to do but in that case, get two AIO instead.

depends, if you want to keep the heat of the two separate then sure, like if you have some super power hungry GPUs and a temperature sensetive CPU or whatever then it can help if you do it right. personaly i just super over speced my rads instead

yeah pretty much this, you end up with one loop a little cooler and one a little warmer depending on how you split your rads, but it's a minor difference

It's just for looks, and often gives higher temps.

AIOs dont perform as well as custom loop

really depends on how you build it, which is entirely the case for all watercooling.

No, like if you have the same number of rads in a single loop or split into two loops, the single loop will always give lower temps when stressing one of the two components (CPU or GPU) and pretty much the same as a dual loop when both are stressed.

 

Maybe a bit higher on the CPU and lower on the GPU since GPUs tend to output more heat and run hotter.

 

Still, the point of dual loops is to add complexity and aesthetics, not performance.

Anyone doing it for performance has no idea how thermodynamics work.

From my understanding, a single- and dual-loop with the same components overall will do practically the same if both loops are given the same radiator space, but the single has more time until it hits its critical point where heat dissipated matches the heat introduced.

If you mean divide the radiator space in two separate loops then yes, performance will be very much the same.
