Low volume tone heard from engine after stopping.

I have 1 year old Karoq petrol and this may have always been happening ?? Doesn't show alarm etc..??
When I switch the engine off after doing a run and get out of car, lock the car etc, as i walk away I can hear a Low volume tone of pitch about 1 kHz approx coming from engine under the bonnet. Sounds a bit like a switched mode power supply or something electronic or a small dc motor whining...??? It stops after about a minute or so.
There are times the radiator fan would be running after stopping engine.... but this tone is not that.
I have lifted the bonnet and listened around, I think it comes from something mounted on the engine rather that a device mounted on the chassis under bonnet.
I dont think it is a fault but curious to find out...??
