Fan speeds up when laptop starts idling

I have an ASUS ROG Strix G17 G713RS-LL008 - 17,3" WQHD 240Hz, AMD Ryzen 9-6900HX, 32GB RAM, 1TB SSD, RTX 3080, FreeDOS

I recently noticed that always when my laptop enters idle mode (after afk) the fans start spinning up hard.

I checked sensors

acpitz-acpi-0

Shortly after the laptop stops idling it’s still at over 5000rpm and the same temps.

i have no idea,
but on KDE there a process named Baloo,it indexes files.
maybe it does that when it sense there is no activity?
