noisy fan on HP pavillion 360

HP Recommended
Microsoft Windows 10 (32-bit)

my HP pavillion laptop has an intermittent VERY loud/rattling fan noise.  whilst it sometimes happens when it is stationary, it always happens as soon as i move the laptop.  i took it to a PC repair, who ordered a new fan based on my S/No, but it didnt fit?  he cleaned the fan and interior, i have updated the BIOS, turned the cooling to passive and turned off 'coolsense'.

 

i still have this issue. it is a HP Pavillion 15-bk100-360 convertible, sadly out of warrantee.  any other suggestions of what next to try? thx

@henrybear, Welcome to the HP Support Community!

 

             

Request you to follow the below troubleshooting steps:-

            

I have a few recommendations: 

  • Thank you for showing your interest in HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. 
    As I understand you want to control fan speed,
    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 shuts down due to overheating?
    Have you recently made any changes on 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 the 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 this link to know how to use HP support assistant.

    The best way to do that is using the HP Guided Troubleshooter: 
    Click here to access it (simply select your description of the issue from the bottom of the screen to gain access to the next set of steps that should resolve your concern).

    If you have followed the instructions and still having issues, I would recommend you go ahead and run an extensive system test from F2(Please capture the failure ID for further assistance).
