Have you try flushing the cooling system ?

The tempatures are not that bad especially when in traffic, the system determines the fan speed and until the temp get to around 230 the fans run at 1/2 speed.....when the temp gets above 230 the ECM turns on a relay that feed a full 12v to the fans and they run at full speed until the engine cools back down. If this really bothers you the ECM chip can be reprogramed to turn the fans on at lower temp.....this set-up was probably done to keep engine noise down.

Thanks
