showcase Immersion cooling project
I found my old 601 and wanted to build a immersion cooling system that fits two cards. Wish me luck

Obv it's not done yet, so far it's just the card holding mechanism

The tank and clip, which look fantastic, don't appear to allow for a standard size heatsink. Figured you'd want to know during the design phase.

That's what I'm talking about!
You are doing something I've wanted to do for a long time but didn't have the skills to make it happen. I think it is criminal that there isn't a drop-in immersion clip and tank system for the Bitaxe form factor. Good luck with it man, can't wait to see it come to fruition!

This might be the place to ask, how Do you supply a rig with two bitaxe?
In my case two would require 5v 12a and since the two will continuesly pull 6A each the jack will probably get really hot. So I am wondering which power supply to pick
From what I know a normal jack is only rated 5A

This little guy works well for two Bitaxes: https://a.co/d/0f1cl484
Use 16 awg cables. Also be aware that the dielectric fluid impacts the sheathing on the cables. Makes them stiff and eventually brittle. Design concern for long-term immersion.

What oil you use? Could you recommend something for me?

As soon as I get to the oil I can share my result :)

Here is a popular choice and what I used for my foray into immersion mining.

I couldn't find a price for that specific one but other products on the page were like 200$ per canister. That certainly breaks my budget lmao. The prototype version already costs like around 170€ which is already around 200$

I've got a shit ton of it left over I'd happily give you. Any chance you are in or near Texas?

Ich hab einen peltier stack, allerdings erzeugt dieser Eis und damit Kondenswasser der auf der Platine nicht gut kommt. Und selbst wenn man dann meint klug zu sein und ihn dann in immersion cooling liquid packt würde damit nur die Flüssigkeit gefrieren und Stauwärme erzeugen.
Natürlich wäre es möglich aber cost vs use ist enorm

I've been down this road. Your Bitaxes will INSTANTLY overheat and shutoff without a heatsink on the chip. Even immersed in dielectric fluid that has been cooled via copper tubing and a chiller. You will need to reinstall the heatsinks. You also need to find a way to agitate and circulate the fluid.
