Rattling sound from front of car when parked.

[Aristophanes88]

Hello,

Since yesterday I've been getting a rattling sound coming from somewhere under the hood of my car when I'm parked and the ignition is off. The sound goes away after 5-10 minutes. The car is a Peugeot 207 from 2008.

I've uploaded a video so you can hear the sound. If anyone has a clue what it might be I'd very much appreciate any info. Thanks

A video in daylight might be more helpful.

But probably a fan or something fouling.

when stationary with the ignition off it can only be the auto cooling fan. Probably something is touching the fan blades.
