Bill....can you go into how your probe is mounted a bit more and your enclosure setup? I had seen the picture the other day, but still had some questions. What keeps the probe from moving around? so you are techniquely measuring the air temp just above(or below) the flexwatt and not the flexwatt itself....I would be would be very nervous that the probe would move and cause temp problems.....have you ever tried using some type of spacer to put the probe in a more fixed position?....just wonderin....I really like to hear about how people have their enclosures setup and their reasons beind it
