A retention module for a heat dissipation assembly is disclosed. In a first embodiment, the retention module may include a frame having an external member and an internal member enclosed within the external member. Furthermore, the internal member is adaptable to seat a heat sink. Additionally, a lever is coupled to the external member, wherein the lever includes a cam. When the lever engages in a first position, the cam pushes the internal member forward to engage the heat sink to a surface. Through the use of the retention module described above, a retention module may be used as a simple method to load and lock heat sinks of varying sizes within a heat dissipation assembly.
