Cannibal fan runs to much

[cdaleracer52]

For some reason the fan on my cannibal runs way to much. Even if the quad is idling and then shut off for less than a minue the fan will run. My friend has a moto, and he thinks its the mapping that makes my fan go off so often, becuase his fan rarely comes on. I tried running engine ice but it made no differance with the fan. I really hope someone could find a solution to my problem.
