Submersible Pump over d5

Recommended Posts

Posted · Original PosterOP

So, as I go into more and more research on a custom desk pc, I've noticed one of the most expensive things about watercooling... the pumps.

Now what I want to know is a Submersible pump a cheap alternative? As Alex said here: "you could probably get a pump off of Amazon for $22." or something like that. I would plan to make some 3d printed adapter for the submersible part of the pump. This pump on Amazon (https://www.amazon.com/Homasy-Submersible-Fountain-Aquarium-Hydroponics/dp/B01LHC8UX8/ref=sr_1_8?crid=15182RWPDOCU5&keywords=submersible+water+pump&qid=1555283381&s=gateway&sprefix=submersible+%2Caps%2C146&sr=8-8) is $24 USD and has around 1500 liters per hours and headroom of only about 2.1 meters of headroom. According to this (https://www.ekwb.com/blog/which-pump-should-you-use-d5-or-ddc/) d5 pumps have about the same lph but 3.9 meters of headroom. How much does this impact performance?

PS: I know there is no PWM controller and it plugs into the wall.

Pressure is what is most important for most watercooling loops. You would be better off to get something that is good quality and reliable than a cheap pump as that is the heart of your loop.

Seriously, how much pump do you need? Everyone's after the D5's when a DDC can easily do the job (for me CPU, GPU, 240, & 360) at 40%.


If you're interested in a product please download and read the manual first.

Don't forget to tag or quote in your reply if you want me to know you've answered or have another question.

honestly, unless you're going for a multi-GPU, multi-CPU, multi-thousand dollar build, there is no reason you should be concerned with pressure. back in the day... people did use pond pumps (just like they used to use straight distilled water) and they got along just fine. Rads just do not put up much of a fight when it comes to restriction. GPU/CPU blocks, now that's a different story. but again, unless you are going for A LOT of them... don't worry about it.

Instead of cheaping out on chinese pumps on amazon buy a proper D5 that will work for years without failing.

Cheapo pumps do work for sure but they tend to be loud, and for a desk PC you really don't want loud.

 

D5 pumps are not loud, once you have all the air out of the loop so the pump isnt churning bubbles though it, its damn near silent, even more so if you suitably decouple it from anything that can transfer vibrations.
