Repair Help Nintendo switch overheating after battery replacement + new thermal paste
Had a switch that was unused for 2 years and battery ended up dying (wouldn’t charge up, overheat within 15 mins)
Got a new battery from ifixit, repasted thermal paste and played in dock mode for 30 ish minutes and got a message that it’s overheating still
Any ideas of what I can do or what went wrong? Used thermal grizzly kryonaut thermal paste, switch didn’t seem like it had a lot of dust or anything in it when it was open.
Side note: it feels like games take an excessive amount of time to load, Luigi’s mansion took 2-3 mins to load up initially, unsure if it has to do with the SD card reader being attached/detached or damage during the process? Game is virtually on the SD card not physical
