1. An apparatus comprising:
a first sensor to measure a first temperature in a first area;
a second sensor to measure a second temperature in a second area adjacent to the first area, the first area separated from the second area by a door;
at least one memory;
instructions; and
processor circuitry to execute the instructions to:
compare the first temperature and the second temperature;
determine a delta temperature corresponding to an absolute difference between the first temperature and the second temperature;
determine one or more door constants;
calculate an adjustment temperature based on the delta temperature and the one or more door constants;
calculate a surface temperature of the door by subtracting the adjustment temperature from the second temperature;
determine a first dewpoint of the first area; and
in response to determining that the surface temperature is greater than the first dewpoint, deactivate a fan located in the first area.
