Abstract: In an example implementation, a computer assembly includes a computer enclosure, a motherboard with an inset edge section that forms a motherboard air gap between the motherboard and a rear wall of the enclosure when the motherboard is installed in the enclosure, a vent opening formed in the enclosure below the motherboard, and an air mover to draw air from above the motherboard, through the air gap, and below the motherboard, and to expel the air drawn below the motherboard from the enclosure through the vent opening.

Abstract: In example implementations, an apparatus is provided. The apparatus includes an air moving device to cool the apparatus, a memory, and a processor. The memory is to store an operational speed-to-noise correlation of the air moving device. The processor is communicatively coupled to the air moving device and the memory. The processor is to receive a noise level selected by a user, determine an operational speed of the air moving device based on the noise level selected by the user and the operational speed-to-noise correlation of the air moving device, and control the air moving device to operate at the operational speed that is determined.

Abstract: A method and system of controlling computer system external effects. At least some of the illustrative embodiments may be a computer system comprising a processor (wherein a computer system user interacting with software executed on the processor triggers a software event), and an external effects controller coupled to the processor (wherein the external effects controller controls at least one device being a purely aesthetic device or a non-aesthetic device operated in a manner for aesthetic reasons). The computer system user selectively associates the at least one device to the software event such that, if associated, upon occurrence of the software event an operational state of the at least one device is changed by the external effects controller.
