So my switch lite which I got pre-owned is having some heating issues and unfortunately I don’t have a video but as the fan spins up say in Botw it just goes full blast like to the point it’s completely unplayable in public no matter the setting and I was hoping to know what could be the issue because I’ve repasted it and tried cleaning both the fan and radiator to no prevail so I was hoping to get some help?
