UPDATE 5/30/18:
The original circuit allowed voltage adjustment from 0-12V. The fan will shut off at around 9V or less, meaning only the last 1/4 turn or so of the potentiometer could be used for adjustment, below this the fan would just stop spinning. I have included a second schematic which uses a Zener diode, changing the voltage range to 9-12V and solving this problem.
Do you wish the fan was more powerful? Try using a 18V or 24V supply for increased maximum airflow (be careful going too
