Hi @jay46531
Here's the [https://h10032.www1.hp.com/ctg/Manual/c08289069.pdf|maintenance and service guide] for the laptop model ''series''.
Go to p.41 to view the procedure to remove the fan.
This will allow you to see what the problem is and also to clean the fan of dust (if necessary) etc.
If the fan is faulty and needs to be replaced, at the top of p.41 you'll find the part numbers for the two fans used in the laptop series. Depending on your particular model specifications, search online for the applicable to your model ''part number only,'' to find suppliers that suit you best. Sometimes the part number is printed on the fan itself, if you wish to confirm that you're getting the correct one.
