If you are referring to the radiator fans, it is because the engine collant is heating up. It is not uncommon for an engine to heat more when driving slowly as less air moves through the radiator and over the engine. If you are concerned about it or the engine temp climbs above the halfway mark on your guage, change the thermostat. If this does not correct it, you should have the engine scoped by a certified mechanic.
It needs to get to a certain temperature for a certaing amount of time for the fans to turn on. When the temp has cooled down enough, the fans will turn back off.

A maze can slow you down by forcing you to navigate through a complex series of pathways and obstacles, leading to confusion and indecision. You may need to backtrack or take longer routes to reach your destination, causing delays in progress. Additionally, the effort required to mentally map out the maze and make decisions at each intersection can consume time and energy.

Cooling fans are controlled by the computer based on input from temperature sensor. After the vehicle is shut down, if the temperature is still high, the computer will turn on the fans to cool the engine.
