Hello,
If I activate the immersion mode, how will it work?
Does the immersion mode with fan regulate normally?

This is correct, it will keep controlling the fans the same. (With Temperature control Auto or Manual).

This is actually just setting the minimum number of required fans to hash to 0, and was simply a cosmetic UI change. Older versions of the firmware had the actual 0 in the miner UI. Regardless, it does the exact same thing.

Ok, I'll try to do some tests.
However, do I have to set my fans manually or will there still be an "automatic" regulation?

I think you can't able to manually set the fan speed if you already enabled the immersion mode.
It will run automatically at full speed without fan check which is already mention above.

Enabling the immersion mode will disable the fan check and actually, it uses usually by those who have immersion cooling tanks or they want their units under the mineral tanks without fans.

No, everything to the fan will ignore if you set or enable the immersion mode.

Some fans are not detected but work fine and even accept pwm throttling, in that case all you need to do is enable immersion mode and restart bosminer. As suggested, factory fan models are recommended as those are what the team tests against. Some after market fans exhibit strange behavior, like not being detected or spin to full when told to do 1%.

Thanks for your help, I will look at this fan and study the blue wire at the ones I bought.

Use the same model that you use before or you can replace it with this model: QFR1212GHE Delta this one is the compatible one.

Or you can try to check the wires it has 4 wires Black, Red, Yellow and Blue.

Legends:

black = ground
red = + 12V
yellow = PWN or Signal Speed
blue = PWM

Check the Blue wire since you said there is no return signal in PWM if this one doesn't have a connection the fan will always run at full speed so focus on that part the wire may not be connected or resoldered properly try to resolder or replace the blue wire and make sure it is connected in the right position to the control board when replugging.

Hello everyone,

I wanted to replace my original fans on my S19 Pro 110T and unfortunately what I ordered are not compatible with Braiins OS+.

They work in manual at 100%, but in automatic does not work, no return to the PMW level. As a result, the mining does not start and the register indicates no fans connected.

Do you have any models to recommend that work perfectly with Braiins OS+ in automatic ?

Thanks

Mickael
