Cooling fan running after engine is turned off

[igorbmwx6]

Just purchased a V-8 4.4L X6 E71 and kind of new to this engine. Before all my X5's had a 3.0L engines and this was not observed with them. Now, every time, after driving the car for a while and then turning the engine off, electric cooling fan in front of the car keeps running for approximately 1 minute even after the engine is turned off. Does anyone, who is familiar with V-8 4.4L engine, know if this is normal or should I start getting concerned with it? Thank you for feedback on this one

Normal. My car does it too all the time. I think i remember someone saying its the design of the engine that needs extra cooling even after the engine shuts down.

Great, thank you!

Yep, normal. My X6M does the same thing. People always think I forgot to turn off the motor or something. She just needs a cooling off period, that's all.

It is cooling turbos.

in the "old days" you would see someone with a turbo drive up then sit there and idle the car for 5-10 minutes to let the turbos cool down.

Turbo cooling function. Completely Normal. If you DON't hear it, you may have a problem.

Hey , I have the x6 3.5 and it happens from time to time .. also sometimes when I turn the car on .. the fan works on high RPM and starts to drop little by little ..
I think this is because of summer and the high temp.
