P2S cooling down fan noise

Hello,
I’ve been printing for a couple of weeks with my new p2s printer.
About a week ago i started hearing quite a loud fan noise after the prints are finished.
It goes on for quite a while. When the fan reduces speed(after +5minutes), it sounds like there might be something ratling or tuching the blades of the fan.

In the display settings on the printer i tried to turn both available fans to 100%, but these are not the fans making the noise.

The noise seems to come from behind or around the print head:(inner left side corner area).

Im trying to attach a video of the issue.

Bambu Lab P2S: 01.02.00.00(Latest version)
AMS 2 PRO: 04.00.21.87
Filament used: Bambu Lab PLA basic filament.

Thanks,
Terje

That’s the noise from the hotend cooling fan—nothing to worry about.

Thanks Axel for your reply!
