auxillary radiator fans on when cold

I have a 93 300se model 140. It is 25 degres outside and my two aux. fans are cycling on and off as I am driving. On for 10 sec. then off 3 sec. Is the coolant Temp. sensor on the fritz?

Changing the temp sensor (blue) that fits into the thermostat housing solved this problem for me.
