They told me that no changes was done on the board, some components were added to the fan and the display.
Can this be true….adding components to make a fan silent, I can understand ( resistor in series perhaps).
But adding components to make the display brighter…
For what I can see without opening the case is, that the fan could be the same as before (Sunon, 2-Wire).
Or not...
In fact, they must have done something with the fan, because the wire are normally fixed on the side by a tie wrap - here, they forgot to fixed it again.
