Abstract

A processor can be damaged by a heat sink. If the heat sink is improperly installed, the heat sink may damage the processor and/or the motherboard. Sequential tightening of mechanical fasteners is thus recommended, but the sequential tightening is challenging to implement. Sequential tightening of fasteners helps reduce damage to a processor. When a heat sink is fastened over the processor to a motherboard, mechanical fasteners are tightened in a sequence to reduce damage to the processor. To ensure sequential tightening of the mechanical fasteners, the heat sink is first secured with only two of the mechanical fasteners preinstalled in two of four holes in the heat sink and sequentially tightened into a bolster plate on a bottom side of the motherboard. A cover is then installed over the heat sink, and the cover has two mechanical fasteners that align with a remaining two of the four holes in the heat sink. A remaining two of the mechanical fasteners may then be sequentially tightened into the bolster plate.
