HP Pavilion - 15-cs3847nd Fan Noise

HP Pavilion - 15-cs3847nd
Microsoft Windows 10 (64-bit)

Last Februari we bought a HP Pavilion - 15-cs3847nd.

In general we are happy with this laptop, but are getting more and more annoyed by the fan noise.


It is a high frequency noise (mechincal / air)  and you get the feeling you are back in time 20 year......
I did some reading on the internet and it sounds like a familiar issue with HP laptops, but i haven't read on a solution.........

Please advise on how we can fix this fan noise....
