Abstract
A heat sink retention system and method secures a heat sink proximate to a packaged electronic component, such as central processing unit, by rotationally engaging the heat sink with a retaining structure secured to an information handling system planar, such as a motherboard. The retaining structure has an opening aligned with the packaged electronic component and securing lips that extend into the opening. The heat sink inserts into the opening and is rotated slightly to engage flanges extending from its base into the securing lips. The position of the securing lips relative to the planar and the thickness of the flanges results in the base of the secured heat sink having a predetermined clearance from the packaged electronic component. A locking detent biases the heat sink to contact the packaged electronic component and allows limited movement out to the predetermined clearance, thus allowing the absorption of shock without excessive heat sink movement.
