Abstract

A computer system including a heat sink including a peripheral portion and a middle portion, a circuit board, a first controller configured to be secured to the circuit board, one or more attachment devices configured to secure the heat sink to the circuit board at the peripheral portion of the heat sink, and a standoff component. The standoff component includes a first threaded section configured to secure the standoff component to the circuit board, and a second threaded section configured to secure the standoff component to the heat sink at the middle portion of the heat sink. The one or more attachment devices and the standoff component are configured to secure the heat sink to the circuit board and allow the heat sink to have thermal contact with the first controller.

Claims (11)

1. A standoff component configured to be secured to a circuit board, comprising:

a first threaded section configured to secure the standoff component to the circuit board;

a second threaded section configured to secure the standoff component to a heat sink; and

a middle section separating the first threaded section and the second threaded section, the middle section comprising a first collar comprising a first thickness, and a second collar comprising a second thickness;

wherein the first threaded section and the second threaded section are configured to secure the heat sink to the circuit board,

such that the first thickness is configured to enable the first collar to enable a spring loaded clip to be secured onto a first controller secured to the circuit board and to enable the first collar to be at a same height as a second controller secured to the circuit board, and

such that the second thickness causes the second collar to be substantially at a same height as the first controller.

2. The standoff component of claim 1 , wherein the second threaded section is further configured to accept a nut, and wherein the second threaded section and the nut cooperate to secure the standoff component to the heat sink.

3. The standoff component of claim 1 , wherein when the standoff component is secured to the circuit board, the second collar is configured to allow the heat sink to have substantially planar thermal contact with a controller secured to the circuit board.

4. The standoff component of claim 1 , wherein the middle section further comprises a head section separating the first collar and the second collar, and wherein the head section is configured for insertion and removal of the standoff component using a wrench.

5. The standoff component of claim 1 , wherein the first threaded section and the second threaded section comprise separate pieces.
