Dual pump parallel or serial?

[ctf05]

My loop will have 2 420mm radiators, 2 140mm radiators, 2 GPU blocks and a CPU block. I'll be working in the Be Quite Dark Base Pro 900 probably with acrylic. Which configuration is better for performance and silence? I'll probably be using the EK-XTOP Revo D5 pump or the EK-XTOP Revo Dual D5. Thanks for any replies.

I usually stuck with serial water cooling.  Parallel has the possibility of uneven flow rate, if the "resistance" of any component is different than another.

i might sound like a hypocrite since i have a parallel loop myself, tough the best and optimal solution is pretty much always serial in terms of performance.

Doesn't matter which you do, flow wise. It only matters if the second pump is for redundancy, depending how you plan on doing dual pumps.

 

So in your case using a dual pump, having the rest of the loop in parallel or series will not effect performance or sound what so ever.

I use the Revo Dual D5 it gives you slightly better performance and you don't have figure out a way to run tubing from Pump A to Pump B(  EK-XTOP Revo D5  - Which can be a pain based on where it's mounted at).

 

The Revo Dual D5 also eats up less space.

Noise is all going be based around vibrations. I added around three layers of rubber before it comes into contact with any surface. You can also try to sound proof your case if you want to reduce the nose even more.

The dual pump he mentioned only has one routing option. If he were to go that route.

I'm talking about  EK-XTOP Revo D5 not the Dual pump top.

Looks like there's two discussions going on. When it comes to dual-pumps, studies have shown that series is the way to go. Parallel dual-pumps provide almost no gain when they are working but also puts a heavy penalty on the flow rate if one was to fail.

 

Long story short, with two pumps, its always better to have them in series, like how the dual-top works.

The discussion about parallel loop configurations is irrelevant to OPs original question.

[Mick Naughty]

Also listing a dual pump and asking if it should be parallel or series is also irrelevant as it can only be used one way.

I suppose OP meant the following

 

I'll probably be either using two of the EK-XTOP Revo D5 pumps or the EK-XTOP Revo Dual D5. 

 

Anyhow, we are on the same boat. Series is the way to go for pumps

I’m doing this idk what run this is lol

If you got that much room for all those rads why not dual loop it ?cpu on one loop then the two gpus on the other loop.
