I'm now starting to think the aircon plays a big part, with fans after shutdown.

lately I've been keeping the aircon in "econ" mode, so doesn't happen, though this evening I went to the milkbar, (which is a 2 min trip at 50kmh) I had the Aircon on "climatic" control, and got about 1 sec of fan after shutdown.
which is kinda weird I think, not like I had the engine running hot, or the turbo going.
