Once the car comes off of idle, the fan will slow down as adequate air will flow through the rad. At idle, it should turn once the temp reaches a certain level.
If it overheated while driving, then you may have another issue. Take it to a shop and have them check the system for you to verify as the hydraulic unit is not and a very expensive guess.
