Welcome to the HP support community.

I understand that the cooling fan is not working, I am glad to assist you.

Clean the air vents to reduce fan workload

Dust and debris can accumulate in and around the air vents over time, obstructing the airflow and causing the fans to work harder than normal to remove the heat.

• Turn off the computer.
• Remove any objects near the computer.
• Use a vacuum to remove the dust from the vents underneath and on the sides of the computer.
• 
• Turn the computer on, and then place it on a hard, level surface, such as a desk or table.

Install the BIOS Update
