An electronic apparatus includes a chassis, a heat generating body provided in the chassis, an antenna configured to be provided in the chassis and be capable of receiving radio waves, an electronic part arranged to be aligned with the antenna within the chassis, and a cooling module configured to have a plate-shaped metal part and cool the heat generating body within the chassis. The metal part includes a shield wall interposed between the antenna and the electronic part.

Electronic apparatus

A method of operating a fan of a computing system includes: measuring a temperature of a subcomponent of the computing system; and comparing the temperature to a temperature threshold. When the temperature is greater or equal to than the temperature threshold, the fan is controlled based on a predetermined table of fan level settings. When the temperature less than the temperature threshold, a fan speed of the fan is measured. When the fan speed is not equal to zero, the method returns to the measurement of the temperature. When the fan speed is equal to zero, the fan is controlled based on a first power determination. The first power determination includes: measuring a system power level; and comparing the system power level to a trigger threshold. When the system power level is greater than the trigger threshold, the fan is activated to a predetermined setting.

Power system based fan control method

An electronic apparatus includes: a chassis; a heating element; a cooling module having a fan, a heat sink, and a heat transport device, the cooling module being configured to cool the heating element. The heat sink includes: a base plate; a plurality of fins standing from the base plate and placed with a gap between the fins to define an air channel through which air from the air outlet flows; and an inclined plate dividing the air channel in two stages in the standing direction of the fins and being gradually inclined from upstream to downstream of the air channel.
