Got it running! Thanks so much for the help!

The fix was to turn immersion mode on, which is what "disables" the fans. They still run, but I guess it stops trying to make sure theyare there? And then I tuned to 800w with that setting turned on.

Going to go through and test tuning at different w next to find what setting has the best efficiency under 1200w.

Again, thanks for the help!

Immersion mode is for water based cooling I guess. In that case you do not need fans...

Just be careful because if your fans do fail, the machine won't turn off automatically and your hashboards will overheat

From what I can tell Braiins has temp controls that will shut it down if you pass a certain temp threshhold.

I think the default is 110c?

It's for mineral oil immersion. You put your whole rig in a pool of mineral oil and circulate it. Apparently it's really efficient in lets you harvest the heat waste. I saw a video where they used a rig to heat a jacuzzi at a bitcoin conference.

Try to sell your heat to your neighboors
