Fan location
Side panels of the device have air vents for heat removal. Two fans are installed on the inside of the right-side
panel, see Fig. 13.
The air flow enters through the perforated left side panel of the device, passes through the entire range of
internal components, cooling each of them, and is brought out with right perforated panel fans. The remaining
panels of the device do not contain ventilation holes, which will allow to maintain the necessary internal pressure of
air flow.
