Can you hook a dimmer switch up to a pc fan so you can control its speed with it? I was thinking it would be a cheaper alternative to buying an adjustable ac/dc adapter.
Depending on how many amps your fan draws, this works great: Newegg.com - ZALMAN FAN MATE 2 Fan Controller - Controller Panels Has a knob to adjust voltage going to the fan. If you need something heavier duty, there are others at newegg. Just search for "fan controller."
