Fan Removal

Heat an iOpener and lay it on the smaller sticker near the bottom of the back panel for two minutes.

Use a pair of angled tweezers to remove the sticker hiding the first screw on the back panel, near the base.

Use an iOpener or hair dryer to heat the larger sticker near the center of the back panel.

Use the flat end of a spudger to scrape up a corner of the larger sticker until you can grip it with a pair of blunt tweezers.

Use blunt tweezers to peel back the sticker to reveal the second screw.

Use a T8 Torx driver to remove the two 7.4 mm‑long screws securing the back panel.

Insert the flat end of a spudger into the gap between the back panel and the shell, near the left side of the base.

Pry up the back panel to release it from the locking clips.

Insert the flat end of a spudger into the gap between the back panel and the shell, near the right side of the base.

Pry up the back panel to release it from the locking clips.

Grip the back panel at the opening you just created and pull it up and away from the shell to unclip the long edges.

Tilt the back panel up and pull it away from the top edge of the shell to release it from the gap.

Remove the back panel.

Use a T8 Torx driver to remove the three screws securing the fan to the center chassis:

One 10.3 mm‑long pancake screw

Use your fingernails or a pair of angled tweezers to firmly grip the edges of the fan cable connector.

Pull the connector straight out of the socket to disconnect it.

Slide the fan out of its slot to remove it.

Before installing the fan, make sure it's clean! Use a dust blower or compressed air to blow off any dust or debris, and wipe the fan clean with a clean cloth.

Note that the fan can only be installed one way—make sure Master Chief is facing you.
