A computer hard drive heat dissipation device for a fixed, swappable or externally connectable hard drive is provided. A heat socket is provided inside a metallic housing, and a heat board is provided on the bottom of the metallic housing. A contact surface where the heat socket and the heat board contact the hard drive, corresponding to a hard drive heat source, is provided with a high heat conductive material or a high heat conductive medium capable of absorbing vibration, enhancing quantitative fit, and conducting heat. The hard drive contact surface and its surrounding space are provided with vibration absorption and sound absorption materials respectively so as to obtain good capabilities in heat dissipation, vibration absorption and sound absorption.
