Actually you have three fans...the main fan behind the shroud and two auxiliary fans.

The main fan is on a clutch, and when engaged, it does spin in proportion to the engine speed.

The auxiliary fans get a signal from the temperature sensor to indicate that additional cooling is needed, and they spin a either a fixed low or high speed, depending on cooling demands.

Actually the W124 cooling system process is a bit complex, with all sorts of backup plans to handle overheating issues. One such plan is that the A/C compressor gets shut down under dire circumstances.

If the weather is mild (not hot) right now, you should be okay.
