Weird new twist.

Now with both new fans connected and running it had decided to stick itself at 615 watts and is keep the temp at about 57c, which would be great, except now its running so cool it's not a very good heater, more of a luke warm fan 🤦.

Ugh. Gonna get there.

Does it maybe have to connect to additional ports? It almost sounds like the fans are just plugged in a power source but not in the control board

I think the PWM wire may be loose or not making proper contact.

Try forcing it to a specific wattage. Configuration > Performance

In the auto tuning section, enable thay and force power target to 800. Save and restart bosminer. Make sure to give it time to tune to "stable". (On your dashboard, tuner status is at the bottom of the page)

After it's stable at 800, check your fan rpms and chip temp. Force it to 1450 watts next and check the fan speeds and chip temp once tuning is stable.

It could be tuning. When I change configs, my miners will sit at around 600ish for a while while its tuning and then ramp up in stages.

Scroll to the very bottom of your dashboard and see the status column. If it is testing, then that's why. It shld say stable when it's done tuning.

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.
