Any of you guys here are getting this vibrating/rattling noise with cold temperature engine start? It almost sounds like a lose bolt on the fan is running. This noise only last for 2-3 seconds and it will go away. At times, it will come back when I'm at a stop.

This noise only happens at low temperature and it goes away when the car is warm up. I wanted to take a video of it but it only happens randomly.

It sounded almost like this but it only last for few seconds.
