Gaming hardware is such hot garbage that even a purpose-built device can't handle the thermals.
It's a dumb device.. it was designed in a time cpu and gpu were the most expensive parts... now that isn't the case and dumbing down hardware doesn't make any sense. But it's too late the design is already made
Its a mini pc. Either lower power limit or accept high temperatures. This looks tall enough for half decent cooling, but if it's hitting 100c it's not great. They sell you on mini pc with a smile and never mention the cooling trap.
