Pump question

[NE0XY]

Hi,

 

I'm planning to add two more radiators so I can run my fans even more quiet, or even completely off when I'm not "doing anything", this will result in a total of 3x Alphacool UT60 140x4 radiators and 1 Alphacool UT60 120x4 radiator. With 1 or 2 fullcover gpu blocks, and a monoblock for ASUS rampage iv BE + cpu.

My question is, will two D5 pumps in serial be able to get a good flow with this much restriction?

 

Thank you

Even one D5 can overcome that restriction.

Hi. Yes, it should be fine.

Yep a D5 can take that loop with ease, no need for a second especially when its rated for 1200L/H

No problem with a single D5/DDC.

Okay thank you guys =)

Well a single pump may be able to overcome that restriction, but it might need to be set higher to do so, meaning it could also be louder. A second pump could allow for better flow at a lower setting, but that'll depend on how much restriction the new radiators and the tubing to reach them introduce -- shouldn't be much, but it might be. Let your temperatures be your guide on that one. The pump will be louder the higher you go, and since you're aiming for a more silent build, a second pump might be worthwhile if you have to have a single D5 up near the highest setting to get good flow.

 Sorry, maybe I wasn't clear. I already have two pumps running on 50% for normal operations and atleast 80-90% when gaming So I'm worried that I have to have the pumps constantly at 80% for normal operations with the new radiators etc. And also to be "future proof" In case I add another graphics card.

No you should not worry about that. Two pumps is still going to be overkill for what you're ending up with along with what you've already got.
