this topic is to much

to kill the condensation you might try a heating element around the chip, this way the chip gets cold and the surrounding is kept warm, vapochill uses this principle to reduce condensation with their setup, it would take nothing more than a wire off an old heater, with low voltage applied it shouldn't scorch anything (i.e. put a potentiometer on it so you can adjust it

)
well, have fun
