- No matter how idle or low CPU load it is, the fan is constantly working.
Core22, unfortunately this is correct. This behaviour is by design and inherited from the previous generation Elitebook 1040 G8 (https://h30434.www3.hp.com/t5/Business-Notebooks/EliteBook-x360-1040-G8-constant-fan-noise/td-p/8338...).
I would advise you to disable "fan always on" in BIOS settings, but I think it's disabled by default. Other than that, there are no conventional (HP firmware/driver updates) ways of rectifying this. You'll just have to live with it........ HP has opted for setting their fans to FULL BLAST across all Alder Lake G9 version laptops (for the sake of warranties probably).

Same here. Clean Windows 11 install, with no apps running. All drivers are up to date (Windows Update + HP Support Assistant + HP Image Assistant).
Even when idling, the fan is on par with a low setting hair dryer.
My company laptop has just been upgraded from EliteBook x360 1030 G2 to G9 and the noise difference is like night and day.

Hello core22 and avicenne13.
You should upgrade as soon as possible to the new BIOS that addresses the fan noise issue:

Thank you for the follow up. I did indeed upgraded to the new BIOS update right away. I am sorry to say that it still is more or less the same.
I know this will always sound a subjective end user concern, but I do miss my 1030 X360 G2 by far.

I have another observation. When I put the laptop somewhere still, the fan quiets down a bit, whereas if I use it on my lap (idling again of course), the fan starts right after.
I saw some setting in the BIOS called 'Motion sensing cool mode'. I wonder if the gyroscope understands that the device is on my lap, and starts increasing the fan for my comfort.

Well, HP does use options that do pretty much what you described, but usually they're in (HP) control programs. You can read about coolsense, one of the oldest ones they used for this purpose HP CoolSense Technology . It's truly interesting that for your model they decided to put it straight in the uefi settings. Have you tried turning it off?

Thank you for your reply.
I indeed googled it - curious to find the root cause - and it seems that even though the Cool Sense is not available in this model, there is a setting in the BIOS similar to it. The bigger mystery is that there is not one single document in the whole web, explaining this option in the BIOS setting.
I did check with 3 identical laptops (company issued) where the machines are loud on fan when used on lap (most probably due to a gyro input) and dead silent after 30 seconds, when put on a desk. I guess the idea is to have the laptop cooler on the users' lap. I wish there was an option in Windows similar to Cool Sense.
What I experienced when turning this option is that, if the laptop's fan level is 8 when used on lap, and 1 on a desk, when I turn it off, it seems a constant 5. However this is quite a subjective experience where I will test some more.
One more time, I have to say that, it is quite interesting to find absolutely 0 reference to that BIOS setting.

Yes, if you take a look at the BIOS (UEFI) Setup Guide For HP using BIOSphere Gen 7-9 2022 there is no mention of an option like this, which is weird, but then again your model is not yet included in this guide. I think that this "coolsense on a BIOS level" option is a new addition, and will be documented in the next revision of the HP bios guides (that include the new x360 g9 models).
BTW, since you're testing, have you tried running the laptop with turbo boost off in BIOS? When I first got my probook G8 it was constantly upping the fan, so I turned TB off until I could fine-tune the tigerlake with throttlestop and finally completely take control over the fan speeds. The laptop with no TB was running 60% of the time fanless.....
