Abstract: In a processor fastening structure, when a compression spring (23) is compressed by shortening a distance between the other end of a screw (24) and a heat sink base (22), the compression spring (23) provides elastic force for both the screw (24) and the heat sink base (22). In addition, because the screw (24) passes through the compression spring (23) to connect to a fastening assembly (21), the elastic force of the compression spring (23) is converted into pressure from the heat sink base (22) to a CPU.
