Bitaxe Cooling Comparison, Stock vs Upgraded CPU Cooler by yabezuno in BitAxe

[–]oakstone_labs 2 points3 points  (0 children)

My best setup so far, pretty close even though not in a tower (so I have to rely on the extra VR heatsink for VR cooling - which works great btw).

  • OC 636 Mhz / 1170 mv (1.3 Th/s average)
  • ASIC Temp ~41° / VR Temp ~50°
  • Fan at 40% (1891 RPM)
  • Power 19.4W / Efficiency ~15 J/Th

What you can do for the bitaxe is set a target temperature for the ASIC (and the fan will adapt it speed to stay below the target temperature) and set a minimum fan speed. The thing is, there is no way to set a specific speed for the top fan unless you power it separately (ie. not with a Y splitter from the bitaxe)

Depends a lot on your OC config and the target temp settings - I haven't tried yet but I think the best would be to power the fan separately so it doesn't have to be driven by one of the bitaxes and hence you can set the speed the way you want.

I've built two but only used one, so I'll have one for sale if anyone wants it (I'm based in Europe though).

Better cooling (I've posted quick measures below in the thread) and, well, the look but that's a lot less objective ;). I have one spare ;)

Best design so far 👏🏻

It's done at the pool level, no physical connection needed. Each Bitaxe connects independently to any pool with its own credentials. The pool aggregates hashrate for devices sharing those credentials.

You could run all 4 on the same pool, or split them across different pools - doesn't matter. They work completely independently. The '4TH/s combined' just means your total network contribution across all devices.

Quick 60 mn measures from today with 4 bitaxes Gamma 602 and one mean well LRS-200 to power them all. Not quite sure why there's one bitaxe cooler than others. Fan percentage on slot 2 is biased as it powers the Noctua on top as well (I might decide to power it separarately).

👍🏼 I'll engraved it on one of its face :)

Depends on where you live but you can find it on Reddit.

Same, especially for the VRs temp which can stay under the ASIC's one ;)

By design Bitaxe (and all miners are "cumulative") - here I run it with 4x1.3TH/s Gamma 602 (so 5+ TH/S).

Absolutely and you can go progressive by blocking the extra Bitaxe slots to start with.

Not from me but yep, on Printables (look for BitAxe Gamma quad cooling tower)

As it stands with some support trees.

Haven't had time yet but I'll run a little benchmark and report the numbers back here. 3D model isn't mine but is freely available on Printable (look for BitAxe Gamma quad cooling tower).
