There were very different replies, let me forward them (with comments).

Comment: A service engineer told me that it's dangerous to remove the cover
        because the air blasted by the fans is no longer canalized to the
        cpu. The result can be a stowing of the heat, and the cpu will die
        a hero's death.
        Nevertheless, I removed the cover, and the machine worked fine since
        that time.

Comment: I'll try to get two additional fans for the left side of the
        system box. Another point is to install air condition in this
        room soon.
