Seems like the simplest and easiest way to have complete control over the full range, including lower end.

At least, I'd imagine the controller gives you complete range control - unlike a 25ohm pot setup.

Honestly, if I had it to build all over again I would probably use one of these : http://www.amazon.com/LEDwholesalers-Dimming-Controller-LED-Lights/dp/B003L4KKF2/ref=sr_1_1?ie=UTF8&qid=1348852396&sr=8-1&keywords=pulse+width+modulator

I have two of them in my control panel for manual control of the SSRs, they work great. But my mine is built with a pot and works fine too.

That's nice. Comes right out of the case. Perfect. I hate not having the lower range of the fan.

I just ordered it. Mine is already built with a pot too, but if this bench tests as well as I hope, it shouldn't be too much effort to switch out my pot for this one, and just mount the controller board to the inside of the project box - the rest of the wiring will stay the same anyway. Thanks.

Nice, but that costs more than I spent for my entire build!

And you have full range control? Or simple 25ohm Rheostat control?

The Amazon PWM controller works great, much better than a simple potentiometer.

You can buy a fan with speed control from Amazon, and the speed pot can be relocated without any problems..
Available in two sizes, 80 & 120 mm.

I got the idea for the stir plate fan from this post

What have you got going on there? Stirplate, built into the floor of tiny, tiny fridge for temp control, and forced filtered fresh air into the headspace?
