Hi,
Since many fans not capable to start properly below 50% of PWM signal, a little spin-up process could help. Otherwise the fan just making some bad noise. With this little optimization, all standard 2 wire fans can work. Also added a little shut-down threshold because several cases the fan just started and stopped and immediately started again and then stopped = made unwanted noises.
