// Use software PWM to drive the fan, as for the heaters. This uses a very low frequency

// is too low, you should also increment SOFT_PWM_SCALE.
//#define FAN_SOFT_PWM
// Incrementing this by 1 will double the software PWM frequency,

// However, control resolution will be halved for each increment;
// at zero value, there are 128 effective control positions.
