The fan on my G9 firefly 14 inch is almost constant running, it's noisy it's loud. Is there any solution to keep the fan under control?
This is my second unit, the first one got really loud fan which was defect on delivery - HP confirmed a hardware defect. This unit got normal noise level, but it's constant while I work in word or excel ... really disappointing.
I need a way to configure a fan profile, any idea?
Solved! Go to Solution.

Hello Koberg and Thomas1789.
I think that you should try out the new BIOS:

Sorry to hear that you are having problems ... I would like to help you.
Let me check your current system configuration before we take a look at the fan ... |

Hi Koberg.
Many users are having issues with the fan(s), either they work less or they work more than they'd like them to....
Except for waiting for a possible BIOS update which will fix the issue, there are few things you can do.
- Unheck/Disable BIOS F10 option: Fan Always on While on AC Power : F10 Settings\Advanced Tab\Built In Devices Menu\Fan Always on While on AC Power https://support.hp.com/us-en/document/c07754576
- Try to control fan(s) with third party software/ create custom fan profile that bypasses the default BIOS fan profile: https://h30434.www3.hp.com/t5/Business-Notebooks/Fan-Control-enablement-required-via-bios-update/m-p...
- Adjust power settings to reduce fan noise. https://support.hp.com/us-en/document/ish_3045299-2819686-16 This can be done through windows 10/11 settings or by directly limiting CPU with third party software (Throttlestop is a good start).

Hello @Ub6424
- Perform <all> tests // Result: every test successfull
- Focus on <Fan tests> // Result: I can't choose the Fan Test with HP PC Hardware Diagnostics Windows, but I could do this in "HP PC Hardware Diagnostics UEFI"
Fan-Speed PASS ID: 21867-06910-61754
Fan-Thermal PASS ID: 21867-06912-61754
The fan speed "jumps" from like 945 RPM to 2800 RPM and back to a lower number and this is noticeable.
This "jumps" shouldn't be there, how can I manually set a better fan curve???
