A heat sink system assembled within a computer enclosure for dissipating heat away from a heat generating element comprises a fan duct, a heat pipe and a fan. The computer enclosure forms an opening. The fan duct is a square hollow shell attached to the computer enclosure, with a surface thereof coupled to the computer enclosure near the opening. A first hole is defined in the surface of the fan duct in communication with the opening, thereby communicating with an exterior of the computer enclosure. A second hole is defined in another surface of the fan duct in communication with an interior of the computer enclosure. The heat pipe includes a main body and two attaching portions at opposite ends thereof for being respectively attached to the heat generating element and the fan duct. The main body has a conductive material disposed therein. The fan is assembled within the first hole.

An attachment includes an upper locking element and a lower locking element assembled together. The upper locking element comprises a main plate, a folded section, a locking section and a locking tip. The lower locking element comprises a spring section, a first and second arms. Protrusions of the upper locking element engage with holes of the lower locking element, and the locking tip engages with a locking slot of the first arm. The lower locking element is strengthened by the upper locking element. The upper locking element acting as a handle for facilitating an assembly/unassembly process of attaching a heat sink to a CPU package.

CPU heat sink attachment

A fan duct for dissipating heat generated by a central processing unit of a computer is disclosed. The fan duct has a main body defining an air inlet and an air outlet. An electrical fan is mounted to the main body below the air outlet. A knob is attached to a top wall of the main body and located above the fan. An enclosure of the computer includes a back panel and a top cover. The top cover is attached with a hook. The fan duct is firstly assembled to the back panel by extending screws through the back panel to threadedly engage with the fan duct. The top cover is then mounted to the back panel to reach a finally assembled position in which the hook engages with the knob, whereby a portion of a weight of the fan is supported by the hook.
