Hi@Anu2Muna, Welcome to the HP Support Community!
Request you to follow the below troubleshooting steps from the document:-
Memory cannot be upgraded HP Pavilion x360 Convertible PC (model numbers 15-bk100 through 15- bk199 and 15-bk000 through 15-bk...
I have a few recommendations:
As I understand you want to control fan speed making noises,
No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution:
Did you know that the fan is system managed and cannot be changed manually?
Does the computer shut down due to overheating?
Have you recently made any changes to the computer before the issue started?
Have you tried to update the drivers and the Bios?
If you didn't, I'm afraid that's how the HP device is designed, making changes to fan speed may cause overclocking or over-throttling causing hardware malfunctions within the device and hence is not recommended or supported by HP.
If your device is overheating, please remember the below information:
NOTE: Generally, when temperatures inside the case rise above 35 degrees Celsius (95 degrees Fahrenheit), the risk of damaging important internal components increases greatly.
Also, to avoid CPU damage, we do not recommend throttling or overclocking the CPU, I recommend you refrain from using high-performance games on this laptop as it's not built for the same.
I would suggest you refer to the support documents as this will help you in resolving the issue.
Let's start off by updating the Bios, Chipset, and graphics card drivers on your PC from our HP support website, using this link.
Also, download and install HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.
Refer to this link to know how to use HP support assistant.
