Just played around with settings to achieve a certain wall thickness and found out that switching fan OFF results in much shorter printing time, i.e. higher printing speed.
With fan to AUTO or any manually selected percentage the printing speed slows down again.
Forgive me if its mentioned in the manual and everybody knows it already, you know, real men don´t read manuals ;)
