is coming from somewhere in the region of nearside end dashboard on my S211 for about 10 minutes after startup and every so often when under way.

Not the main fan because it is still evident when that is switched off.

Is there another one in there, perhaps a cooling fan for electronics?

It really is very, very annoying!

I'm sure there should be a fan in the ECU box in the engine bay. It's probably transmitting noise to the car.
