[erikvandermeer]

Just bought a new laptop pavilion 15 CS1855 ND

Fan is continues running ( i think acting normally) but comes with an irritating high frequency tone. 

is this normal? Im fully distracted during work and starts to irritate after 5 minutes. 

I did all the updtes, installed new BIOS and went true all support proposals from HP.  

How can I stop the fan noise with this new notebook.

Hi! @erikvandermeer,

Were there any recent windows update on the PC?

Please share the product number of the PC to assist you better.

Try restoring the BIOS to default.

1.    Turn off the computer and wait five seconds.
2.    Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3.    On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4.    Press F10 to Save and Exit.
5.    Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6.    Follow the prompts to restart your computer.

Try updating the thermal framework drivers on the PC to the latest version.

Also, try the steps recommended below.

To properly ventilate the computer, allow at least 7.6 cm (3 in) of clearance on the left side
of the computer. The computer uses an electric fan for ventilation. The fan is controlled by a temperature
sensor and is designed to turn on automatically when high-temperature conditions exist. These conditions
are affected by high external temperatures, system power consumption, power management/battery
conservation configurations, battery fast charging, and software requirements. Exhaust air is displaced
through the ventilation grill located on the left side of the computer.

Lastly, try running a system diagnostics test on your PC and check if the hardware components on your PC are functioning correctly.
