Introdução

Use this guide to replace the heatsink in your Steam Deck, or remove it for replacing thermal paste.

Before you begin, completely power down and unplug all cables from your Steam Deck. Remember to follow general electrostatic discharge (ESD) safety procedures while repairing the device.

    • To minimize risk of damage, turn on your Steam Deck and allow the battery to discharge below 25% before starting your repairs. A charged lithium-ion battery can be very dangerous if accidentally punctured.

    • Before starting this guide, power down your Steam Deck and unplug any cables.

    • As an extra precaution, Valve recommends putting your Steam Deck into battery storage mode within the BIOS before starting any internal repairs. Read how to do that here.

    • If you have a microSD card installed, make sure to remove it before opening the Steam Deck.

    • Use a Phillips driver to remove the eight screws securing the back cover:

    • Four 9.5 mm screws

    • Four 5.8 mm screws

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your Steam Deck.

    • Insert an opening pick into the thin gap between the back cover and the front shell, along the edge of the right grip.

    • Pry up on the back cover to release it from the locking clips.

    • Once the clips are disconnected from one edge, the rest disconnect easily.

    • Grip the back cover at the opening you just created and pull it up and away from the device to unclip the long edges.

    • Remove the back cover.

    • Use a pair of tweezers to remove the piece of foil tape covering the hidden screw on the board shield.

    • If possible, try not to rip or tear this tape so it can be reused. If necessary, you can fashion a replacement by cutting a piece of aluminum foil tape to fit.

    • Use a pair of tweezers to remove the sticker from the top edge of the fan.

    • If possible, try not to rip or tear this sticker so it can be reused. Use a little bit of heat if necessary to soften the adhesive.

    • One captive 3.5 mm screw

    • One 3.4 mm screw

    • No, your eyes don't deceive you! The third heatsink screw was removed earlier in the disassembly: it doubles as the hidden board shield screw.

This was incredibly easy. I changed the thermal past for some MX-4 and saw a 3-5 degree decrease and quieter fan speeds!

When will iFixIt sell the heatsink itself? I want another just in case.
