The symptoms
A fan that's gone from whisper to jet engine, or grinds and rattles. The console hot to the touch in the dock. The dreaded warning — “The software was closed because the console got too hot” — or sudden shutdowns mid-game. Heat problems creep up slowly, and by the time a Switch is shutting down, it's been cooking itself for a while.
Why it happens
Two things degrade together over years: dust packs into the fan and heatsink fins until air can barely move, and the factory thermal paste between the processor and heatsink dries out and stops transferring heat. Either alone makes the fan scream; together they cause thermal shutdowns — and sustained heat shortens the life of everything else on the board.
What the service includes
A full internal clean of the fan, heatsink, and vents, fresh thermal paste on the processor, and a fan replacement with new hardware if yours is worn or grinding — all covered by the one $59 flat price, along with testing under load, tracked return shipping, and the 90-day warranty. Most consoles come back noticeably quieter and cooler within 48 hours of arrival.
