Water cooling loop question.
Water cooling loop question.
hahapingazzz :
Seanie, if worse came to worse is a single D5 pump enough to push through two 480 rads and two blocks while still maintaining low temps?
I would be pushing both gpus (1080 TI's) to their absolute limits and anything above 60C under full load would be unacceptable
To give you an idea, I am using a D5 at power level 3, fastest is level 5, to push the water through 2 x 360mm rads first then into an EK CPU waterblock with a high pressure plate and then back to the res, so I think you should be fine, my temps dont go over 58oC on my CPU under linX, IBT or Prime95 Full stress.
It looks like everything would work just fine if it were necessary. Thank you for your assistance. A D5 is the top pump available, with a maximum flow of 1500 LPH.
A single D5 can handle two GPU blocks and 480 rads without issue.
I'm testing a GTX1080/i7 6700 with a Phobya DC12-400 pump (1530 RPM, max under 2000) and a Black Ice Nemisis 420 rad, using just three Noctua 140mm fans running below 1000 RPM. The GPU hasn't reached 54C yet. This setup isn't overclocked—I'm not motivated to tweak it further.
😉
Even with a strong dual 480 rads and one D5, the GPUs will stay very cool.
If you're using thick (over 35MM) rads or high-density fins, make sure to use high static pressure fans—they often have 'SP' in the part code. High airflow fans (usually marked 'AF') won't push cool air through thick rads as efficiently.
Coozie, I'm thinking about ordering 40mm think rads and using Riing Plus RGB fans. Although these fans are considered high static pressure, their pressure is only about 1.5mmh2o, which isn't the maximum available. Would you think they'd be sufficient for a 40mm thick rad? The rads are EK coolstream PE 480 rads with an FPI of 38 or 19 split.

I'm using slim rads with Thermaltake Riing RGB fans 120mm, adjusting the front one and just pushing on the top one. I don't see the need to pay £100 for a plus version when three fans cost only £300. Previously, I used Noctua NF-F12 fans, but the 70's look felt a bit dull for the tempered glass case.
2 x 360s is a bit excessive for just the CPU, but I'm planning to add the GPU later. I wouldn't change the EK full cover block without a reference card, and it would require minor adjustments to fit.
For better understanding – radiators are among the least restrictive parts in a loop. Even with a bigger radiator, the restriction remains minimal. You’d actually need just one pump, even if you’re using a dual card loop. Additionally, why would a GPU loop require two radiators? It depends on the cards being used; you should consider loop TDP rather than simply adding large radiators unless necessary. There’s a limit to how many radiators you can use before it becomes less effective.
Pumps work by both drawing in and pushing water – they need to pull water into the intake to push it out. Imagine a rope on a pulley: pulling the rope also pushes it forward. This happens simultaneously within the same loop, which is why there’s no separate idea of a pump pushing or pulling water through a loop – it does both at once.
