What ventilation clearance is required for the HP 255 G6, and how does the fan work?

Allow at least 7.6 cm (3.0 in) of clearance on the left side of the computer for proper ventilation, as exhaust air is displaced through the ventilation grill on the left side. The fan is controlled by a temperature sensor and is designed to turn on automatically when high temperature conditions exist, which can be affected by high external temperatures, system power consumption, battery fast charging, and software requirements.
