Dear Davlo:
I see you are getting a nitwit answer(s), trying to make YOU look like
the nitwit.

However, in newer (I don't know how new) conventional/convection
ovens, the answer is:

"While in a preheat mode, the convection fan will reach it's target
temperature faster."

This is different than just pressing or turning a knob to a certain
'bake' temperature.
