Depending on the fan (I don't know that one), first establish which way it should sit on the socket. Basically the HS should be central over the chip. Then carefully slot in the three seats to the side of the clip without the handle for you to push on. Lay the HSF down onto the chip, make sure your first three anchors are properly engaged. Now take the handle, and slowly and evenly apply pressure downwards so the clip is forced towards the anchor. Keep applying more pressure, until the clip snaps into place on the socket. Then plug the fan in to the mobo.
