Building A Water Cooled Raspberry Pi 4 Cluster

I built a water cooled Raspberry Pi 4 a couple of weeks ago. This was obviously crazy overkill for a single Raspberry Pi, but it isn't actually why I bought the water cooling kit, I bought it along with 7 other Raspberry Pis so that I could try building my own water cooled Pi Cluster. I've really enjoyed the past few weekends putting it together. So, here's a video of my Pi 4 cluster build, I hope you enjoy it!

That looks gorgeous. It's appropriate that if there's a coolant leak that the whole thing will look like it's bleeding. :O

[dhmketu]

that cable management is just next level.

GREAT BUILD!.... I actually would love you to cover the software isde of the cluster.
Thanks!

This is why I still love IT and tech after studying/working with it for over 50 years ! Yep learned fortran as a 15yo :) Loved this video.

I bet even a person who has no clue what Raspberry PI is going to love this video. Well done mate.

[LincsOracle]

Looks brilliant and love the black and red. Only comment with the actual build is I would have rotated the Pi's on the right by 180° so the coolant was on the right and mirror the coolant on the left.

First of all, that´s an amazing job thank you so much for sharing with us... but i´ve seen in the video few air bubbles flowing into the circuit and it may be a problem because you lose eficiency in the heat transfer and air also affect to the pump, making it to cavitate. A posible solution, make sure that you don´t feed the pump with any air bubble just by setting it vertical, or rotating 180º the radiator to keep the air trapped in the upper part of the radiator.

Thank you for the time you spend making this video, and greetings from Spain. Keep it up!

that's probably the coolest pi cluster out there.

[alicangul]

Would love to see how much processing power per watt you can squeeze out of it.

It looks like a breaching charge that a SWAT team would use, looks awesome.

[ScammerRevolts]

Nice build! looks really nice, def love the red color!

[leegibson]

Hell with the cluster. I want this guys tool shed. Damn.

[teodor]

Nice work! Really love how it looks. Please do cover all the software that you will be using on this in a video! Looking forward to watch it! Take care and be safe!

That sir is a work of art as well as functional.

For anyone who knows about water cooling, having it in series is the only way to go. That water flow is usually fast enough to warm up evenly so there is no noticeable difference between each node. Usually what you have is the loop thermal balance.

jayztwocents did a good video about it.

[freddurst]

Love these types of vids, HATE when they use tools most everyday people do not have access to.

[deechvogt]

Wow Maker Michael!! This is totally neat. I was wondering about surface mounting the radiator but then saw you had cut a hole through. I would love to know how the thermal performance the individual nodes. Look forward to seeing what you are planning to do with this neat cluster. Keep up the good work and congrats on the 10K subscriber mark!!

[TheBeardedBoofhead]

That thing is ridiculous...
I love it! ☺️

[ruttabl]

Man this video makes me miss using laser cutters all the time. They're so nice!

[seanregehr]

Good project.

If you are concerned about water temperature, might I suggest you run the radiator and fan from the rear of the display and insert some thermal barrier to isolate the heat from the cold. Likely you would not require much but can likely cool the water by a degree or two under load. Also adding longer tubes would allow the water to cool more before it even reaches the radiator.

I would have gone with a circular arrangement myself by that is just personal taste.
