The fan usually starts several layers into the print, so as keep the first layer hotter, to help with bed adhesion.

Also when the nozzle is close to the bed, the fan cools the nozzle more than normal. Cooling the nozzle can cause underextrusion.

The latest cura increases the fan very gradually (by default). I think so the PID controller can adjust a little bit after each layer so that the nozzle doesn't get too cold.

Once I went from 0% to 100% on a layer and got underextrusion for about 60 seconds.

I haven't upgraded Marlin since the printer arrived in September.
