Hi Yahoo123,
Welcome to Sony Community!
We're sorry to hear on what happened to your laptop. May we know how did you clean the fan? Did you disassemble any wires/ cables inside? If you did, try to redo it and make sure you put everything in place. If the issue still exists, we recommend that you bring the unit to the repair center.
