I meant that if there is any other way to control the fans.

I tried both of the solutions you proposed, and I think that the second
one suits me better. The temperature in the begining is kept around 45C,
and after I while around 60C. So it is 10 degrees Celcius lower that
previous.

Thank you very much! Kind regards,
