The main challenge is driving a 1200x1080 VR AMOLED panel, which doesn't natively communicate with the Deck's motherboard and requires a custom adapter PCB — for now, the device outputs to a TV. Cooling is handled by a 3D-printed mount for a 30x7mm fan and heatsink, and a -50mV CPU/GPU undervolt keeps temperatures around 70–80°C during gaming. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What cooling solution is used when fitting a Steam Deck motherboard into a compact custom shell? A 30x7mm fan and heatsink with a 3D-printed mount, combined with a -50mV CPU and GPU undervolt, keeps temperatures around 70°C during lighter games like Tunic and around 80°C in more demanding titles like Clair Obscur. _Builders tackling Steam Deck thermal mods share results like these on daily.dev._ ## Similar posts on daily.dev - [Someone modded their Steam Deck to look like an Xbox 360 handheld, and I'm in love](https://daily.dev/posts/someone-modded-their-steam-deck-to-look-like-an-xbox-360-handheld-and-i-m-in-love-x7nn18uyw) · XDA Developers · 1 upvotes · 0 comments - [Getting the Steam Deck LCD working on a Raspberry Pi](https://daily.dev/posts/getting-the-steam-deck-lcd-working-on-a-raspberry-pi-79fcqdi0n) · Jeff Geerling · 2 upvotes · 0 comments - [The Steam Deck taught PC handheld makers the wrong lesson](https://daily.dev/posts/the-steam-deck-taught-pc-handheld-makers-the-wrong-lesson-zfx6hn5jq) · XDA Developers · 2 upvotes · 0 comments - [Engineer Creates Steam Machine With Custom 3D-Printed Case](https://daily.dev/posts/engineer-creates-steam-machine-with-custom-3d-printed-case-6d2m0hszz) · 80 LEVEL · 0 upvotes · 1 comments - [Make A DIY E-ink Faceplate For Valve’s Steam Machine](https://daily.dev/posts/make-a-diy-e-ink-faceplate-for-valve-s-steam-machine-0fgetpja9) · Hackaday · 0 upvotes · 0 comments --- Tags: [#steam-deck](https://daily.dev/tags/steam-deck) [View this post on daily.dev](https://daily.dev/posts/someone-squeezed-the-steam-deck-s-hardware-into-a-custom-game-boy-shell-and-it-looks-amazing-ulqpph4al) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Someone squeezed the Steam Deck's hardware into a custom Game Boy shell, and it looks amazing","url":"https://daily.dev/posts/someone-squeezed-the-steam-deck-s-hardware-into-a-custom-game-boy-shell-and-it-looks-amazing-ulqpph4al","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/someone-squeezed-the-steam-deck-s-hardware-into-a-custom-game-boy-shell-and-it-looks-amazing-ulqpph4al"},"datePublished":"2026-08-10T23:11:08.674Z","dateModified":"2026-09-14T06:16:48.098Z","description":"A maker called PhyFawkes has built the 'SteamBoy' by fitting a Steam Deck motherboard, battery, speakers, and buttons into a custom Game Boy-sized shell.
