What the hell are you talking about? Of course you can easily put two pumps behind each other or in parallel. Pumps in parallel improves the flow. If unrestrained flow was given it would be double in fact. Pumps in line would improve the pressure. This is literally middle school physics and is used in a TON of applications... many of them industrial but hey, what do engineers know. It is SUCTION where a dual system would not work (as easily, there are special setups for that too). Which is also why you can simply put two air compressors into parallel for improved flow, but not vacuum cleaners for example. If you use two pumps you could even undersize them and optimize for BEP or variflow scenarios. You could even just build a quick disconnect and valved overflow into the loop if you wanted hot swap if that's a desired spec desired. I'm really irritated to see such a baseless video. If I'm being honest it should be remade entirely. I'm fine with a statement like "gamers likely don't need failovers, high pressure loops" etc. but you guys even sell MO-RA3's in your own webshop (tested to 5 bar...) and you're trying to tell us to run industrial or e.g. a basement radiator setup with a freaking solo pump...
After 20years+ in the watercooling business this question has come up again and again. And my answer is still the same: Do not use parallel pumps or parallel cooling (like 2 GPU). Never do that. Always in-line. Middle school physics are good for getting grades, but not for computer water cooing loops.
Looking for information on the MO-RA3 420 D5-DUALTOP. I see UA-cam channels building with this device and ostensibly claiming that there is increased flow with a two pump design. A video showing the most efficient way of connecting this pump configuration with a heatkiller tube discussing fittings, tube size and assembly to a radiator would be a great help. Is correct that the flow rate is increased with two pumps?
I have an external 540 rad with koolance QDC's. 1 pump was barely enough. I have to run it on speed 5. 2 pumps on speed 1 works well enough but only about 2 LPM.
Hello, let me give another scenario for the "do I need 2 pumps in my system?" question. Here's a loop example that I have in mind : - 1x CPU block (like the Core 1 Aurora Black); - 1x GPU block + 1x active backplate ; - 2x 420mm 45mm thickness X-flow radiators; - soft tubing - 1x VPP Apex pump with flat reservoir or a distro plate. Now, here comes the... unusual part. I want to add 4x Eiszapfen quick release connectors to the loop, 2 for the CPU block and 2 for the GPU block/active backplate, so I can easily change them in the future without draining the whole thing. Those connectors introduce a hefty amount of pressure loss (or head loss, pressure drop etc) in the loop. But I can't find this technical info on them, the value for their specific pressure loss. So my question: Is 1 VPP Apex pump enough to push through all off those accessories and connectors at a good flow rate? Or do I need 2 VPP Apex pumps in series ? It would be great if you could help me with this info or make a video about it. Thank you!
@@aquatuningtv Hello, no, I'm making a single loop with all of the mentioned accessories. That's why I'm asking if 1x VPP Apex pump is sufficient to cover them all. Or I need 2x VPP Apex pumps in the same loop to cover the extra pressure loss introduced by the 4 quick release connectors. Thank you!
@@Shinnok789 I'm currently working on a fairly big build with multiple radiators and blocks. I'm running two pumps. I think one would do but not as good as two. I'm working through all the problems as I've never built anything this ambitious. It is fun to learn and expensive!
very similar setup here, I run a d5 next and 2 aquacomputer ones off an ultitop. when i cbf changing cases it will be more of a requirement as ill got to 3 420 45mm's@@Shinnok789

This is such an amazing product and worth a video, I have put this on our list :-)

That is right, if you have 2 loops, then you can also have 2 pumps.

Last night, my EKWB D5 pump bearing just exploded. It's only 4 years old with maintenance done yearly and no exotic coolants used.
I had the same experience also with EK D5 from Lowara, but they sent me new replacement.
This is so sad to hear. 4 years still is some time.
where do I connect them?
There are TWIN-tops for some pumps available, or just with fittings and tubing.
