I have a FR4 board with a copper track over it and I apply some amps in the copper track. As a result I have the temperature map on this track and board... I also have a heat transfer coefficient of (10 W/m2.k) over the top side of the board.

The question is: If I have an external temperature of 25 Celcius with a very low current (0.005A for example) I have some points of temperature below 25C (24,961 Celcius) Why, is it possible?
