A Vietnamese TikToker has gone through the arduous effort of strapping a full-blown 240mm AIO liquid cooler onto a Steam Deck handheld gaming console. The video shows the entire creation process, which involved building a custom baseplate for the Deck and drilling out part of the rear clamshell to make room for the AIO. However, after all that hard work, thermals dropped by 32%, giving the Steam Deck's little Van Gough APU more than enough thermal headroom to hit peak boost clocks.
Despite its success, this mod is not for the faint of heart and required drilling and damaging the Steam Deck outer shell. If you value your Steam Deck's longevity, this is something you probably should not attempt to try.
