Valve have warned all Steam Deck users against modding their devices, adding that doing so will result in a massive reduction in the console’s lifespan.
It’s no secret that players have been modding the console left and right to replace its SSD. Valve designer Lawrence Yang responded to a Eurogamer article, saying:
“Hi, please don’t do this. The charger IC gets very hot and nearby thermal pads should not be moved. In addition, most 2242 m.2 drives draw more power and get hotter than what Deck is designed for. This mod may appear to work but will significantly shorten the life of your Deck.”
So yeah, if you don’t want your Steam Deck to melt, don’t mod it. You have been warned!
