Abstract: An electronic device includes an immersion tank and a server. The server includes a casing, a circuit board, a primary heat source, a secondary heat source and a radiator. The casing is vertically disposed in the immersion tank, and has a side plate. The circuit board is disposed on the side plate, and has a front surface and a back surface facing away from each other. The back surface faces toward the side plate. The primary heat source is disposed on the back surface. The secondary heat source is disposed on the front surface. An amount of heat generated by the secondary heat source is less than an amount of heat generated by the primary heat source. The radiator is disposed on the side plate, and is thermally coupled to the primary heat source.

Abstract: A fan speed control method performing by a baseboard management controller includes following steps: obtaining a first temperature from a first temperature sensor, determining a first rotational speed according to the first temperature and a proportional-integral-derivative (PID) equation, wherein a proportional term of the PID equation is: ? 0 t f ? ( E ? V ? ( t ) , p ) [ EV ? ( t ) ] 2 ? d ? t - ? 0 t - ? ? t f ? ( E ? V ? ( t - ? ? t ) , p ) [ EV ? ( t - ? ? t ) ] 2 ? dt ; where t denotes time, ?t denotes an interval time, EV(t) denotes an error between the first temperature and a set temperature when the time is t, EV?(t) denotes a first derivative of EV(t), ƒ(EV(t),p) denotes a coefficient of the proportional term, and controlling said at least one fan according to said at least the first rotational speed.

Abstract: An electronic device includes: a battery, a mainboard, and a housing. The battery is connected to the mainboard, the mainboard is provided with a first controller, the battery and the mainboard are installed in a cavity of the housing, and the housing includes a rear cover. The rear cover includes an electrochromic layer, the electrochromic layer is connected to the mainboard, the first controller is configured to control whether to power on the electrochromic layer, and a color displayed on the electrochromic layer when the electrochromic layer is powered on is different from a color displayed when the electrochromic layer is not powered on. The rear cover can change, by controlling a power-on and power-off status of the electrochromic layer, a color displayed on the electrochromic layer, and further change a color displayed on the rear cover, without changing a decorative film.
