With PICs I think the max life is calculated on the max speed.

My first industrial application with a PIC (BS2 actually) was back in 2000. The control panel is out side in the ambient Temperatures of SW Arizona. 120 F in the shade in the summer. The machine runs 6 days a week for 10 to 12 hours a day. Still going strong.

The only time I ever had a hot PIC was...well I do not like to talk about it
