Macbook Air is being slow and the fan is constantly running
my MacBook is being super slow and it is making a fan sound. i know when it makes that sound it means its over heating but its not hot at all and it hasn’t been outside where it could get over heated. i have tried everything i reset it, shut it down, done a SMC reset and nothing is working. it has been doing this since last night and the fan won’t stop being loud and it just keeps running so slow. Even netflix is lagging, I have tried other internet networks and nothing is working. Please help
