That one is nice! Thanks a lot for that... And yes, Michael, same here. I am not veru convinced, that everything is well tested and tested for all use cases... The fan is a nice idea also - these real world solytion does not pop up in my head easily...they are kind of too real ;) I will use a fan, if smartctl i.e. will report high temperatures... Cheers!
