Abstract

Abstract The present invention is a computer housing with a low noise cooling system. The computer housing is comprised of two principal members, a cover and a base. Both a left surface and a right surface of the cover are perforated with vents to allowing the passage of air through the housing. The base additionally incorporates two air intake holes with a power source for the computer disposed over these air intake holes. The passage of air through the housing is facilitated through the use of three fans. These three fans are attached directly to the power source, and each of these fans operates at a different fan speed. The fan speeds are additionally adjusted in response to the outside ambient temperature. In operation, air enters the computer housing of the present invention through the vent array on the left surface of the cover, and the air intake holes in the base. The air is then channeled under the power source, dissipating the heat generated by the power source, blown across the components in the housing, and passed out of the housing through the vent array disposed on the left surface of the cover. The flow of air from one of the fans is advantageously deflected and channeled with a deflector.
