Abstract: Apparatus for securing or retaining a heatsink. The heatsink retention apparatus includes a heatsink module that cooperates with first and second spring loaded latches secure to a circuit board on opposing sides of a heat-generating component. The heatsink module includes a handle pivotally secured to opposing sides of the heatsink body, and bails pivotally secured to the handle. In addition, the bails extend downward to dispose a lower bail member adjacent the spring loaded latches. As the handle pivots between a first position to raise the bails and a second position to lower the bails, the bails automatically move from a locked position to an unlocked position. Each of the spring loaded latches include a hook and at least one pre-loaded spring to transfer a minimum downforce to the lower bail members when the bails are raised. Accordingly, embodiments may be operated from the top of the heatsink without the use of tools, while providing a desired downforce over a range of heatsink heights.
