Abstract: In example implementations, an apparatus is provided. The apparatus includes an accelerometer, a plurality of fan blades, a coil magnet and a processor. The accelerometer is coupled to a motor to measure an amount of vibration. The plurality of fan blades is coupled to the motor. Each one of the plurality of fan blades comprises a magnet. The coil magnet is coupled to a fan housing that encloses the motor, the plurality of fan blades and the accelerometer. The processor is communicatively coupled to the motor, the accelerometer, and the coil magnet. The processor activates the coil magnet to control a balance of the plurality of fan blades in response to an amount of vibration measured by the accelerometer that exceeds a threshold.

Abstract: Examples of a cover for a device are described herein. The cover includes a substrate to be placed in proximity of a heat source of a device. In an example, a heat resistant layer is applied over a surface of the substrate to insulate heat generated by the heat source. Further, a top layer is applied over one of the heat resistant layer and another surface of the substrate, which is opposite to the surface having the heat resistant layer. The top layer provides at least one of chemical resistant properties and aesthetic properties.
