SER Pro AI 9 HX 370 makes a strange humming sound.

Sorry for my English. I have a problem with Beelink SER Pro AI 9 HX 370. Bought in Slovakia through the official Beelink dealer… https://www.beelink.sk/mini-kompaktny-pc/mini-pc-beelink-ser9-ai-32gb-ram-1-5tb-disk/
A friend bought it for me for his company. Windows 11 Pro SK was newly installed on the PC. The original drivers from the original Windows 11 were backed up. I had a problem with the graphics card driver. I have a KTC H27P22S monitor. Via HDMI cable it goes (3840 × 2160) 120Hz. But via DP (3840 × 2160) only 60Hz. When I select 120Hz or 160Hz the screen remains black. No image. Where could the error be?
I thought that after installing a clean Windows 11Pro SK everything would work. But it didn’t.. it doesn’t work! The backup drivers were installed and the latest AMD driver for the graphics card. However, the computer started making a strange sound. It happens every time I go to Windows settings and move around in the menu. It also does it in the web browser when I move around pages and scroll through them. It’s not the hum of a fan, it spins silently. It’s a kind of whirring!
It doesn’t do it when I turn on video or music. When I turned Windows into safe mode, it didn’t do it there. How could a driver cause it? Could that be the case?
I wrote to Beelink in Slovakia for technical support. But no one has heard back yet. Can you please advise me how to remove the whirring? I also wrote to support-pc@bee-link.com. They advised me to clear the CMOS memory. But that didn’t help either. It still whirs the same way. Should I send my computer in for service or reinstall Windows 11 Pro? I am sending you my PC’s serial number and a short video where you can hear the growling sound. You need to set the video volume to maximum.
I found out that I can’t upload the video. But I already put it on the internet storage. Here is the link to download the video https://files.fm/u/vkx8gh2jh3

Thank you very much for your help. Image description

Hi there
What cable do you use , DP to DP or DP to HDMI?
If the DP port is 1.4 Version, please buy an active DP1.4 to HMDI2.1 cable ,here is the reference ：

May i know if the sound from the fan ?
1.You can also try Softwares : HWMonitor、SpeedFan to optimize the fan .

Currently I have the monitor connected via HDMI and the cable that came with the PC. When I had DP to DP connected I used the original KTC cable that came with the monitor.
1. The growling noise coming from the PC is coming from the bottom. Not from the back where the fan blows air.
