Hi Many times people underestimate the amount of heat sinking required with a TEC. If you get into fans, they introduce a whole new set of issues ….It’s not just the heat you are getting out of the “oven”. The TEC it’s self makes a pretty good thermal short (compared to foam insulation). You have to “pump” across that as well.
