Hi @crookdvd1980,

Welcome to the HP Support Community. 

I'd like to help!

If you have performed all the steps from this document and still having issues, the Fans need to be changed but sometimes other components too like Thermal paste, etc.

I suggest you contact HP Support for Service Options

Hope this helps! Keep me posted for further assistance.
