  1. Are the pushpins bent or broken? Those fans don't do well for re-use. You'd be better off getting a new fan or cooler. I would recommend one w/ a mobo bracket for secure installation.
  2. Theses heatsinks dont have push pins , they clip then lock in place with a lever
  3. Might wanna try installing it with the motherboard out of the case...
