Hey!
I want to re use a S19 J Pro i have as a space heater, the problem is noise an power usage. Currently i am using braiins OS+ and the lowest power limit i can set is 1700w for all 3 hashboards. The firmware will not let me go any lower. And the hashboards overheat with Noctua fans running at 2000rpm (for noise)
Ideally would be if it was possible to set it at 1kw for all 3 hashboards.
Om my S9 i can set it as low as 300w and it enough to run it with low noise as it help keeping the bathroom warm. 1.7 kw is too much for the apartment and too noisy.
Anyone else been experimenting with this?

2 boards of 3 set to 60th will give you 40th and 1200 watts.
fans set to 30% will be fairly quiet

you can get it fairly quiet but not truly quiet rpm at 3000 or so.
or you could really effort by buying this controller

and these fans

when set to 30% speed they will be good enough to cool the unit if you run 2 boards at 60th giving 40th and 1200 watts
they will do about 2800 rpm and be marginally quieter.
