Abstract
Abstract A heat sink assembly for the central processor of a computer is provided in which the heat sink is selected from metal materials of good thermal conductivity. The heat sink comprises an array of heat conductive posts which define a free space for a fan. A number of grooves disposed between said posts are provided to engage a base plate. The fan is coupled to the base plate and can rotate in the free space. Two columns or rows of the heat conductive posts take the form of a hook such that the base plate when compressed can be engaged with these hooks. The base plate is provided with protrusions to secure to the grooves.
