It depends on the motor.
To quote MarkT from this post:
The simple advice is you can't. Standard induction motors in domestic appliances cannot safely be speed-controlled (some can be a little, but its not easy to find out by how much).
Get a DC fan
To quote dc42, from this post:
What sort of motors do the fans have? If they use induction motors, then you won't be able to control the speed much using phase angle switching - the speed is tied to the supply frequency. If they are series-wound motors with brushes, then phase angle switching should work.
The results you reported when you tried to use the velleman kit suggests to me that the fans may have induction motors.
