What #bitaxe settings are you using?
Running 575Mhz / 1.250V
Discussion
1) 485Mhz / 1200V. 57C. BD = 889M
2) 525Mhz / 1259V. 60C. BD = 1.06G
3) 550Mhz / 1200V. 59C. BD = 7.58M
Aghh. 2) was supposed to read 1250V.
Depends on the silicon lottery. I have some that do have better avg hashrate and are more stable when undervolting and staying around 500mhz, and others that need the juice. Still others that can be pushed *hard* and consistently get into the high 700s.
I run large north bridge heat sinks that have 2 heat pipes and a noctua 8mm fan to cool them all in the low 40s.
Trying to figure out the most ideal form factor of a “case” to mount them to with a 5v rail they can all share with a single larger power supply.
Been a fun little experiment! May try liquid cooling, next. Then going to work on expanding the ideas to support the hex or 0xAxe (which doesn’t look ideal to build).
Wow your setup sounds bad ass! Im going to look into the north bridge heatsink upgrade! Mind providing the part number?
I would love to figure out how to run one power supply and connect multiple supras to it... + a few large noctua fans. any ideas? Would clean up my setup a lot!

You can’t really find them anywhere else cheaper, even aliexpress. I haven’t found any other heat sinks as beefy and that fit relatively OK onto the board. It comes with a cutout foam pad to try to keep it level, but it is still gonna be a little unwieldy.
Pair it with a noctua 80mm PWM 5v: https://www.amazon.com/Noctua-NF-A8-5V-PWM-Premium-Quality/dp/B07DXMF32M
Depending on your climate, you may not even need the fan.
I mounted mine so that the fan blows horizontally, tho I may change that depending on how I end up mounting the board in a case.
That will drop temps into the 40s, max 50C unless you’re being dumb. Use a good thermal grease - I go with good ‘ol mx-4. Good longevity.
Still working on the power distribution option. Looking for best bang for the buck.
Going to design a case and print it out. Thinking modular to be able to add more on vertically or horizontally.
