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.

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.

Use the flat end of a spudger to pry up the locking tab holding the base to the shell.

Keep the locking tab held open for the next step.

With the locking tab held open, grip the base and rotate it counterclockwise to unlock it from the shell.

Remove the base.

Use an iOpener or a hair dryer to heat the USB port cable.

Slide an opening pick under the USB port cable to separate the adhesive securing it.

Use a pair of tweezers to gently pull up on the black plastic pull tab to disconnect the USB port cable.

Move the USB port cable out of the way of the chassis.

Use the pointed end of a spudger to depress the metal tab on the side of the power button cable's board connector.

With the metal tab depressed, use a pair of tweezers to pull up on the pull tab to disconnect the power button cable from the center chassis.

Use a T8 Torx driver to remove the three 7.4 mm‑long green screws securing the center chassis assembly to the shell.

Grip the chassis and pull it towards the top of the shell, uncoupling the guide pegs from the shell.

Use two hands to lift out the chassis to remove it from the shell.

Two pegs on the chassis with cutouts on the bottom of the shell.

Three pegs in the shell with cutouts on the chassis.

Gently place the chassis heatsink-side down on a clean work surface.

Use an iOpener or a hair dryer to heat the USB board cable.

Peel up the section of USB board cable near the outer edge of the shell to separate the adhesive.

Slide an opening pick under the section of the cable closest to the board to separate the adhesive.

Use a T8 Torx driver to remove the two 8.9 mm‑long screws securing the USB board enclosure:

One screw inside the shell

One screw on the bottom of the shell (where the base was)

Use your fingers to slide the USB board enclosure out from under the metal clip securing it to the shell.

Remove the enclosure.

Make sure the Pair button is properly oriented and fully inserted in its slot.

Firmly slide the enclosure into position until it snaps into place under the metal clip.
