We found 5 Reddit comments about DROK 180057 LM2596 Analog Control Buck Converter DC-DC 4-32V to 1.25-30V Step-down Regulator Module 24V 12V to 5V 3A Power Inverter Volt Stabilizer with Red LED Display. Here are the top ones, ranked by their Reddit score.
Analog Control: adjust the screw on top of the potentiometer clockwise or counterclockwise to increase or decrease the output voltage.Has very stable output, the output range is DC 1.25~30.0V, please note the input voltage should be higher than output voltage at least 2V.Press the MODE switch, the display will cycle through the output voltage, output current and input voltage.The output voltage can be turned on/off by the ON/OFF switch, when the output is off, the digital tube will display OFF.With reversed polarity protection and short circuit protection, more safe to use; the display is very accurate.
you want a buck converter. there are plenty of adjustable ones. eg http://www.amazon.com/dp/B019RKVMKU

That one does have a built in current limiter that is controllable ... so you need to make sure the output is 12vdc, and the current out is either unlimited or 1amp or more... It is possible to starve a fan for current and slow it down

How about this one: https://www.amazon.com/DROK-090029-Numerical-Switching-Adjustable/dp/B019RKVMKU/ref=sr_1_1?ie=UTF8&qid=1480536531&sr=8-1&keywords=DROK%C2%AE%2BLM2596&th=1
It seems to have what I want, though the chip seems to be a TI knockoff
You could also use a buck DC converter to step down the voltage to dim instead of a dimmer like that which is PWM. PWM is more efficient, but be aware that if the dimmer's PWM frequency isn't really high (10Khz+), you will see flickering/banding in any video recorded from the lighting.
Here is a buck converter that uses a little screw to step down the voltage as much or as little as want. As long as the DC voltage out is less than the DC in, it can step down. This type of converter wont affect any video/photography since its not PWM.
