Question about Computers & Internet
There are 2 fans at least on the inside. One is for the CPU and the other is for the power supply. They are supposed to run continuously to keep the heat from building up inside the case. (Heat is what is worst for your CPU.) It sounds like the noise itself is what is disturbing you. Unfortunately, there isn't much that can be done for the sound level created by the fans. My wife subscribes to the theory of turning up the music a little louder to drown out the noise of my graphics card fan. The only cure would be to invest in a lower noise fan- you'll see decibel ratings on some of them.
You can get a can of compressed air and take off the CPU fan to clean off any accumulated dust on the fins.
If you find this solution helpful, please rate it accordingly.

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.
First clean your computer of dust you could use a fine air blower from a compressor or a can of compressed air whatever you use make absolutely sure there is no moisture in the airlines
if the fan in your computer is constantly running to cool down the cpu and it is normal for it to increase it's speed, your fan should run quietly even it increases the rpm.
But if you hear a loud noise in the fan, i think there's something wrong with it.
I suggest for you to check the fan if it's coming in contact with anything. If the fan is visible while your computer is operating, you can observe it to know what is really happening.
I don't know what type of fan hp uses on their computers, maybe something is loose already on the fan so better check it or bring it to an hp service center.
make sure your CPU has thermal paste
your CPU might be getting hot making you computers fan to run consistently
hope this helps
