# Python scripts for changing fan speed on MD1200
|
||||
|
||||
A set of scripts that automagically set fan speed on a MD1200 (probably MD1220 as well) based on internal temperature readings.
|
||||
This adjusts fan speed "dynamically" based on average backplane temperature reading.

Working working working.

So far seems to work.
|

|

## STM32F103C6T6
|

I think it needs a MAX2323 between MD1200.
|

|

Will look into that.
