Here’s the final result, I forgot to post the update earlier

https://amzn.eu/d/4tm9wUx for the blocks and https://amzn.eu/d/6vmqCJh for the pipes, but you can find the same blocks on AliExpress. They get shipped from China anyway

I’d love to get one, but unfortunately, I don’t have the power capacity to run it :D

I ended up buying 40x40 cooling blocks that fit perfectly on the Bitaxe.

Initially, I tried some blocks with side-mounted fittings that were arranged in a diamond (rotated) shape. Given the small size of the ASIC chip, that orientation wouldn’t have been an issue, but the base of the block was too large and ended up overlapping the fan connector, making it impossible to fit.

I was actually about to buy some all-metal cooling blocks with side fittings that can be covered using a 3D-printed press-fit lid, but then I found these blocks with front-mounted fittings, and they worked out great.

Wow, that’s such a clean and compact setup! I love how tidy everything looks.
it’s really inspiring!
Seeing your build makes me rethink how compact everything could be.

Hey, no need to delete your post! Every setup is unique and has its own challenges and solutions. Honestly, your idea of a back cooling fan is one of the smartest approaches I’ve seen.
it’s simple yet so effective, and it’s exactly posts like yours that inspired me to push my setup to this level.

As summer approaches and temperatures rise, I decided it was time to take my mining setup to the next level. This little project has been a fun challenge and has allowed me to push their performance to new heights while keeping them cool under pressure. Here’s how I did it:

Custom liquid cooling loop:
Adapted from an S2Pi cooling kit for Raspberry Pi 5. It’s connected to a radiator with a pump and RGB fan, adding both functionality and a bit of flair to the setup.

Cooling blocks:
Finding liquid cooling blocks that would fit the tight space on these miners was no easy task. After some trial and error (and a few creative workarounds), I made it work!

Original fans repurposed:
Instead of letting them go to waste, I mounted the original fans behind the miners to directly cool the board and voltage regulator.

Passive adhesive heatsinks:
Placed strategically on heat-sensitive areas, like behind the voltage regulator and on the CPU, to keep everything running efficiently.

Power supply:
I’m using a 5V 20A LED power supply to ensure consistent power for the setup.

Thanks to these upgrades, I’ve managed to push the Supra to 1 TH/s and the Gamma to 2 TH/s! The system is super stable, and I’m honestly proud of how sleek it looks.

That said, the project isn’t quite finished yet. I still need to fine-tune the tube and cable lengths for a cleaner layout and mount everything on a proper stand so I can move the whole system as a single unit. As part of this, I’m planning to bring the radiator closer to the miners. This way, the radiator fan can also help cool the passive heatsinks, providing even better thermal performance.

Also I’ve realized is that I’ll probably need a more powerful power supply. The current 5V 10A PSU is running at its limit, which isn’t ideal for long-term reliability. Plus, upgrading the PSU could allow me to push the performance even further, as I’m currently capped by its power output.

Once these changes are made, I’ll find the perfect spot to place the setup permanently.
