ABSTRACT:
To isolate a computer housing structure from vibration created by an internal cooling fan, the fan is provided with a pair of specially designed resilient vibration isolation members. In one embodiment, the vibration isolation members each comprise a spaced pair of pocketed end portions having generally triangular cross-sections and joined by a thin strip of resilient material. These end portions are fitted onto the corners of the fan's rectangular outer frame which is then pushed forwardly into a rectangular mounting frame, the pocketed isolation member end portions serving to space the inserted fan frame apart from the mounting frame. The rear side of the mounting frame is then secured to an inner side surface of the computer housing structure.
