My Word on Monday - or rather, "A Pleb Manifesto for EVERYONE". A regular pleb wants the thing to run stably and not sound like a hair dryer with emotional trauma. Open source requires more than just open files if open hardware is to be taken seriously.

In 2024, we had three new Bitaxe generations, a new finding at the end of the year in the form of the Low Profile Plus cooler and much more.

In 2025, an holistic and generic cooling solution now exists, all packed into a simple cube. Which is not so simple after all.

Many thanks to the many supporters who have accompanied me so far. 2025 is just beginning and I still have so many ideas.

The crowning conclusion of the long series of tests with three #Bitaxe generations on the #OCaxe is complete. The last test with an Ultra, which I soldered myself, was the final straw.

With the newly designed and optimized adapter for the Ultra & Supra, the ICE tower is doing really well on the Ultra. Unbelievable 1012 Mhz (904 Th/s on average) under air cooling - in fact I have experimented a lot with Bitaxe Supra. But never so intensively with the Ultra, which is still absolutely competitive and can push the hash rate. Of course, the BM1370 can't be overhauled... but the Ultra remains a robust iron pig.

Now it's time for the evaluation phase and writing the test article, with all the test data, detailed views and so much more.

Next step: the 4-hole adapter for the 52Pi ICE-Tower does not fit the #Bitaxe Ultra and Supra, which each have only two holes (or capacitors/USB-C in the way).

So the construction of the adapter had to be adapted so that the one-sided torsion of the adapter sits firmly on the cooler, but above all on the PCB. The already optimized distance between the cooler and the ASIC was also taken into consideration here and should be adhered to. The ASIC is given optimal contact pressure and also serves as an angle support for the entire adapter.

I would not recommend copper plates for this adapter because they are not 100% flat and can therefore damage the ASIC even faster.

I noticed today that two of my #Bitaxe Gamma with an ICE tower are overheating. That would be another two units that still had the adapter supplied - so I wanted to print a new adapter, made of PETG. It seems that the seller simply printed adapters in PLA for me at the time. They are not suitable for this purpose at all, because PLA starts to deform at temperatures as low as 65°C.

You can see that nicely on the adapter itself (see photo). I never thought about it before, but unfortunately the adapter is not quite optimally designed.

On the one hand, the distance from the cooler to the ASIC is 1.3mm, so you have to tighten the screws much more to ensure that the adapter is firmly attached to the PCB and that the ASIC is connected to the cooler. This also explains why adding a copper plate improved things: a connecting layer was simply added under increased pressure.

Furthermore, the adapter also encloses the heat pipe around the cooler, both at the front and at the back. So practically the hottest points when the cooler tries to dissipate the heat. Furthermore, the adapter obscures the air circulation under the adapter but also to the heat pipe itself, which makes cooling more difficult.

I have now created an optimized adapter for the Ice Tower, which consists of two parts, is much more robust and removes all the disadvantages mentioned above. The copper plate is no longer needed, the ASIC sits exactly on the heat pipe. In addition, the distance between the cooler and the ASIC and the contact pressure on the PCB have been significantly improved.

The first test showed that with a newly printed adapter that I always used before and my new one, a temperature drop of 5°C occurred on the ASIC.

“The king is dead, long live the king”, as bitter as that sounds. #Bitaxe Gamma on steroids and he still remains a cool dude. But just see for yourself, I still can't believe it.

@NarlySolana What exactly do you mean by “they”?

[PlebBase @realPlebBase]

Ice Tower, Argon THRML 60mm and the “Ötzi” on the Bitaxe Gamma, what can they do? https://t.co/h0n4Tzg5Bi

Current review of the new Bitaxe Gamma, with incredible potential compared to the Supra and previous generations.
