European Minibook 8 j4125 fan noise

Hello
I just got my minibook 8 Celeron j4125 version and really love this pic except for the very noisy fan.
Since I like reading books on my PC at night, the noise is really annoying since the fan is always on.
For the j4125 European version, is there a bios update or modified EC available for the fan not to run at low temperatures?
Is there a bios setting available for that?
Even at a 6w TDP, the fan is running at very low load (5% CPU usage…)…
Thank you very much!
Regards
Nicolas
