Metalic "click" sound inside unit after stoping using it

Hello i want to ask if after some use when i keep it on and wait some minutes i heard some metalic “clack” sound inside unit .This never happened to me before and my room is warmer this days dont know if can be related to cooldown or something, i dont feel anything wrong with the unit so i dont know whats going on.


I did some tests, i reverted firmware tweaked some settings but still get one or two after playing or just lying on desktop with it powered on.

Guys sorry for posting this but the sound was getting me crazy but after do a hard search on my rig im 99% that it comes from the pedals. Lock or delete if posible to not confuse people.
