According to Volvo´s new features release information in 2006, regarding engine D5244T4 the cooling fan was supposed to work afterrun in order "to protect various engine components from overheating".
Mine doesn´t work when I stop the car, unless I've been driving with air conditioning on. Is this normal, does it have to be always working for a certain time after switching off engine?

Afterrun
The cooling fan is activated for a certain time after the engine has been switched off in order to protect
various engine components from overheating.
Fan activation time and fan speed are dependent on coolant temperature and driving style (engine load) when
the engine is switched off. Afterrun takes place as follows:
• Initially a high speed is used, following which the speed is lowered in stages. There are three
"variants".
• When stage 4 (top fan speed) is used the afterrun initially continues for 360 seconds.
When stage 3 (intermediate speed) is used the afterrun initially continues for 255 seconds.
When stage 2 (next lowest speed) is used the afterrun initially continues for 150 seconds.
