ABSTRACT:
A method is disclosed for securing a heat sink against a central processing unit. The present invention teaches a heat sink securement device having a vertical retention arm that substantially encompasses a heat sink in a vertical direction, a horizontal retention arm that substantially encompasses a heat sink in a horizontal direction, and a tension arm coupled to the vertical and horizontal retention arms and pivotally coupled to the frame, the tension arm simultaneously adjusts a tension on the vertical retention arm and the horizontal retention arm in response to moving the tension arm. In certain embodiments, the retention arms are coupled to the tension arm via coupling member that is offset from pivot point of the tension arm. In other embodiments, the coupling member may include a different coupling member for the vertical and horizontal retention arms, both coupling members offset from the pivot point.
