Heat dissipation assembly with fan mounting device

A heat dissipation assembly, comprising:

• a heat sink comprising a chassis, a raised fin extending upwardly from each of opposite ends of the chassis, a bulge formed on an upper portion of the raised fin, and a cutout defined in the bulge;
• two clips rotatablely mounted in the cutouts of the heat sink, each of the clips comprising a main body, a mounting portion extending inwardly from a lower end of the main body and a pressing portion extending inwardly from an upper end of the main body in a same direction as the mounting portion;
• and
• a fan provided at a top of the heat sink and defining a bottom plane;
• wherein the mounting portions of the clips engage with the fan to retain the fan in position parallel to the plane, and the pressing portions press the fan toward the heat sink to retain the fan in position perpendicular to the plane.

A heat sink assembly comprising:

• a heat sink defining a chassis with a plurality fins extending upwardly therefrom along a lengthwise direction;
• a fan located above said fins;
• a pair of clips respectively moveably located on top portions of two sides of the heat sink, each of said clips substantially defining a U-shaped configuration having a main body with means pivotally mounted to the corresponding top portion, a pressing portion extending from an upper end of said main body toward said fan and perpendicular to said main body, and a mounting portion extending from a lower end of the main body toward said fan and perpendicular to said main body;
• wherein
• a distance between said pressing portion and said mounting portion is essentially equal to a thickness of said fan so that the fan is able to be releasably retained between said pressing portion and said mounting portion.
