I am experiencing a similar issue but with a new build - I flashed katapult and then klipper according to the supplied instructions.

Despite everything else working just fine (RGB addressable, thermistor reading, CAN communication etc) the fans and thermistor don't appear to function.

Multimeter reading across HE0 (PB13 / GND) shows a reading of around 1V.
