Klipper has this: [Display\_template for fan control](https://klipper.discourse.group/t/display-template-for-fan-control/20375)  
Another example: [TMC2240 use temp for fan control](https://klipper.discourse.group/t/tmc2240-use-temp-for-fan-control/25703)  
It should cover most of the cases where one needs “custom” behaviour

_Otherwise, regarding the PSU’s Fan, normally it is enough to use a thermostat to do so.  
Internally, it is possible to either attach it to the MOSFETs or to the inductor coil._
