MacBook Pro 16" fan noise issue.

My MacBook Pro 16" one makes lot of fan noise, when I connected to the external monitor.

Tried multiple connectors but no luck.

Any solution will be appreciated.


Thanks,

One insight proposed early on for the 16"MBP is power plugged into the right hand side port,


external monitor plugged directly into left hand side port. Avoid a hub


Keep your Mac notebook within acceptable operating temperatures
