A device with a PCB with forced airflow has a housing including a first panel (141) and a second panel (142). Within the housing is mounted a printed circuit board (111) with heat dissipating elements, an opening (112), a first surface (131) and a second surface (132). The first surface (131) of the printed circuit board (111) is located at a distance from the first panel (141) smaller than a distance between the second surface (132) and the second panel (142). To the printed circuit board (111) is mounted a fan (113) that covers the opening (112) and forces airflow from a space between the first surface (131) and the first panel (141) to a space adjacent the second surface (132).
