The temperature is constantly increasing, See the video https://cloud.mail.ru/public/L3Nu/L6GEKocG3
Also, if the temperature fluctuate about 39.5 or 40 degree then the fan turns on and off, unable to get going.

Yes, with the current firmware, the P906 turns on the fan at 40 degrees Celsius and turns it off when the temperature drops below 40 degrees Celsius. When the actual temperature is around 40 degrees Celsius, it is possible that the fan will turn on intermittently. We will optimize the fan activation logic in subsequent firmware releases.
