Remove the following screws securing the motherboard to the metal casing:

• Nine gold 11 mm T10 Torx screws.
• Eight black 5.6 mm T8 Torx screws.

If you are reassembling your Xbox 360 after installing the Red Ring of Death Fix Kit, the eight T8 Torx screws circled in orange are not reused.

Turn the Xbox over, being careful not to let the motherboard fall out of the chassis.

Lift the motherboard assembly from its front edge.

Be careful not to damage the sockets as you rotate the motherboard away from the metal casing.

Remove the motherboard assembly from the metal casing.

Insert the tip of a small flathead screwdriver between the X clamp and its retaining post on the heat sink.

Pry the X clamp away from its retaining post until it is lifted above the small groove cut into the retaining post.

Insert your screwdriver parallel to the motherboard between the X clamp and its retaining post.

Twist the screwdriver to fully release the X clamp from its retaining post.

Repeat this process for all four corners of the X clamp.

When removing the last corner of the X clamp and holding the motherboard upside down, be sure to catch the GPU heat sink to avoid damage from it falling.

To reinstall the X clamp, first start by attaching two corners to the posts on the heat sink.

While holding the third arm of the X clamp down against the post attached to the heat sink, use a small flathead screwdriver to pry the X clamp away from the heat sink post.

As you pry, press down on the arm of the X clamp until you "walk" it down into the retaining groove cut into the post attached to the heat sink.

Repeat this process for the fourth arm of the X clamp.

Remove the GPU heat sink.

Before reinstalling the GPU heat sink, be sure to apply a new layer of thermal paste.

If you need to mount the heat sink back onto the motherboard, we have a thermal paste guide that makes replacing the thermal compound easy.
