The first base is installed on the first side, and the second base is installed on the second side. A minimum outer dimension of the main body falls in the middle section, and the air inlet holes face away from the air outlet holes. The projection lens is installed on the main body and located at the same side as the air outlet holes. The fan is installed in the main body.

A computing device is provided, including one or more processing devices, one or more temperature sensors, a fan, and a fan tachometer. The one or more processing devices may be configured to execute an application program. While executing the application program, the one or more processing devices may be further configured to collect performance data including temperature data received from the one or more temperature sensors and fan speed data received from the fan tachometer. The one or more processing devices may be further configured to generate a fan control signal at least in part by applying a machine learning model to the performance data. The one or more processing devices may be further configured to control the fan according to the fan control signal.

A hardware-based fan controller for controlling fan modules in a computer system having multiple computer nodes is disclosed. Each of the computer nodes has a service processor. The fan controller includes a slave module that receives fan speed commands from each of the service processors. A fan speed generator is coupled to the slave module and a subset of the fan modules. The fan speed generator receives fan speed commands from the slave module and fan speed outputs from the subset of fan modules. The fan speed generator is configured to output a speed command to each of the fan modules in the subset.

A mobile device case is described. The mobile device case includes a housing configured to retain a mobile device and an active cooling system integrated into the housing. The active cooling system configured to use vibrational motion to cool a surface of the mobile device.

A power supply for a computer includes a base having a bottom panel and two end panels being respectively provided with a plurality of first and second fastening sections; a fan assembly having a first frame provided with a plurality of third fastening sections located corresponding to the first fastening sections, and a heat dissipation fan fixed to the first frame; an internal part assembly including a second frame located on the bottom panel and provided with a plurality of fourth fastening sections located corresponding to the second fastening sections, and an internal part unit mounted on the second frame; and a cover being configured complementary to and covered on the base. All the fastening sections are located in a receiving space defined between the base and the cover, and the cover and the bottom panel of the base are free of any fastening holes for fastening purpose.

A projection device configured to project an image in a projection direction is provided. The projection device includes a housing and a projection module. The housing has an air inlet and an air outlet, wherein the air inlet, the air outlet and the projection direction are in the same direction. The projection module is disposed inside the housing. The projection direction and a direction of gravity are in the same direction.

A fan management system includes a chassis housing a storage fan system, a storage system cooled by the storage fan system, computing fan subsystems, and computing devices cooled by respective ones of the computing fan subsystems. Each of the computing devices detects a multi-computing-device configuration that includes the computing devices and, in response, determines a computing device chassis location for that computing device. Each computing device then receives fan inventory information that describes the storage fan system and the computing fan subsystems, distinguishes between the storage fan system and the computing fan subsystems based on the fan inventory information, identifies the computing fan subsystem that is configured to cool that computing device based on the computing device chassis location for that computing device, manages the computing fan subsystem that is configured to cool that computing device, and ignores the others of the computing fan subsystems.
