A heat sink fixture for fixing a heat sink to a heat generating device is disclosed. The heat sink fixture at least has a suppressing section, two force-exertion sections and two fixing sections. The suppressing section is used to suppress the heat sink. The force-exertion sections are respectively bent upwards and extended away from both ends of the suppressing section. The ends of the force-exertion sections are bent and hollow. The fixing sections are respectively extended from the force-exertion sections for being fixed to the heat generating device. The heat sink fixture decreases difficulty in assembling.
