Either the CPU fan is clogged with dust or has failed, clean or replace the fan.

See this guide for cleaning instructions

Can I ask for instructions for disassemble the notebook and how to clean the CPU fan?

[Mumbodog]

You don't need to disassemble to clean the fan, the link I posted earlier showed how using canned air.

Your Service Manual can be found on this page

If you have no warranty:

Best thing to do is call HP parts

 call (800) 227-8164 between 5 AM and 5 PM Pacific Time, Monday thru Friday.

they will ask for serial numbers from the PC, this way they can get you the correct part number.

It requires some skill to replace the fan, its not for the inexperienced. I suggest taking it to a qualified reputable repair shop to install it.
