Single or Double Pump?

Go to solution Solved by Oshino Shinobu,

Thx for the anwser, I was also guessing the same since the D5 pushes about 1500l/h while the raijintek barely pushes 500, but I wasn't sure about the head pressure which it had. Regarding the laing setup, I was refering to using one or two ddc pumps.

A single D5 is a better solution than two DDC pumps and certainly better than a single one. 

 

TBH, unless you really need to save on space, I wouldn't consider anything but a D5, it beats pretty much everything else in most categories. Even if you do need to save on space, EK's D5 Revo units are pretty small. 

Hi guys,

I recently redid my water cooling loop and have some issues with my pump. I have a Raijintek RAI-PM5 pump and I am almost sure that  it cannot cope with the new number of radiators. My loop is: pump > thin 240 > thick 240 > GPU > thick 480 > cpu >reservoir. The gpu temps are alright, but the cpu is not getting enough coolant. I know that the RAI-PM5 is pretty bad and I wanted to upgrade for a while but I don't know if I shoulg go for a single D5 pump or Dual D5 setup. Also, if you think that a laing setup instead of a D5 one is better, please let me know.

Thanks in advance!

Depends on how much power you need to push all of that water(In short, it depends on how long your loop is) personally, i have never built one of those, but yeah this is a thing that i know, so cant really tell....

A single D5 will handle it fine. Going for two will give you redundancy, but it's not needed in terms of pressure. 

 

D5 pumps are made by Laing though..... So a D5 is a Laing setup.

It also depends on the power that the pumps will output. Typically the faster the pump runs it outputs more pressure, like a car engine I guess. I have only used one water pump in my time in computers but I honestly can't remember the speed or if i had to use more then one. 

Have you tried turning it off and on again?

I did end up getting a d5 but I think that I might be doing something wrong since even this seems to not quite cut it. Anyways I'll keep on troubleshooting

If its a quality pump there isn't an issue with it. Either air in the loop or user error. Not enough stuff in that loop to give that pump a problem.
