This tear-down of the Steam Deck talks about the battery, the fan and replacement fans (wasn’t easy to find!), heatsink design, screw placement, MOSFET, inductor, voltage regulator, and battery charging IC specs, and more. We’ll cover the VRM current capabilities in this as well, with a lesson on how they work and what they do (for anyone new to this stuff to get introduced). Our hardware review of the Steam Deck is already live on the channel and covered everything else, like battery life, but our focus here is “repairability,” access, overall build quality, and design details.
