I'm testing my HM for the first time on a new build smoker.
The damper/fan is running at around 90% to maintain 105C / 220F.
You can see that when it closed around 3:57pm the temp dropped very quickly. This probably means I dont have any air leaks! But does it also mean its not naturally drawing air effectively?

EDIT: Thrown more charcoal on at 5:04pm. I think I was just running on too little fuel.
