The 5 Best DC fan Speed controls (2023 reviews)

Riorand makes beautiful and outstanding control with classic and higher-grade materials. It is perfect for a temp fix of a blower motor. It is custom made for lighting fixtures. It controls the speed of the fans well, but it emits a high pitched sound when it is not at full load. It has a nice red led inside to let you know when power is going to the device.

It is adjustable with the control knob on the side. It is great for turning down the speed until they get the hang out of it. The onboard LED changes brightness with turning the knob, and the small 12V motor connected to the output does run.

Why We Like This:

Capable of controling lots of amps
Working well for a 12v fan, but emits a high pitched sound
Slows them down to a crawl if needed
Good unit smooth operation easy to hook up

Best For your system Voltage: Hima DC fan Speed Control

Buy on Amazon

For a low asking price, hima dc fan speed control has managed to overwhelm their customers by packing as many features as they could. This controller specifies use in a motor with brushes. It features in your f/r design to prevent switching overlap and you'll damage something eventually. It can change speed or stop under changing load from hard rain or snow. In general, yes it can be used to control a heating element as long as you are not exceeding the ratings of the controller. The potentiometer knob allows adjustments from 0% to 100% depending on how much power you want the vehicle to have.

The DC motor driver can be used to brush motor speed regulation, light dimming regulation in the dc circuit. It provides only a steady output voltage at lower than input. It's affordable and fantastic for prototypes.

Why We Like This:

Works for 18v battery power wheels conversion
Works great, using it to control a trolling motor from a kayak
Nice compact pwm for brush motors

Best For adding Speed Control: PEMENOL DC fan Speed Control

Buy on Amazon

If you often find yourself scrambling for convenient and suitable control, pemenol dc fan speed control is your end point. This motor speed controller module uses Pulse Width Modulation (PWM) to adjust the speed of the connected motor. It is a pwm controller that can change the frequency and duty cycle of the output signal. It has a soft-start protection function that can effectively reduce the inrush current, protect the motor and prolong the life of the motor. It is easy to break it down for board access to solder-in remote-switch wiring. The knob has smooth indents as you turn it, indicating the PW percentage on the LED display. It is suitable for use in machine control.

The controller has a anti-reverse protection on the input.

Why We Like This:

Easy-enough to set-up and engineered to be user-accessible for wiring, repairs, etc
Simple and easy motor speed controller
Great and easy to operate pwm speed control
Excellent use to control computer fans used in a rv refrig for air circulation

Best For dimming leds: Wayintop DC fan Speed Control

Buy on Amazon

If you often find yourself scrambling for appropriate and satisfactory control, wayintop dc fan speed control should be your first option for buying. The motor comes from princess auto surplus, a gear drive. It works well with low voltage 4.5 volts (3 AA batteries) so far so good. It should be a square wave with an adjustable duty cycle. There is a massive SS14 Schottky diode across the motor terminals. It has a tiny but bright red led light to display when it is on. The pulses have a short duration, and when used with an inductive load, such as a motor, the pulses smooth out.

The potentiometer has a click switch between off and on.

Why We Like This:

Compact dc pulse width modulation controller
You can run electric motors, pumps, etc
Works well, small form factor, well-made
Noticeable problems under 1 amp 100% duty cycle at 12 v dc

Best unit: Acogedor DC fan Speed Control

Buy on Amazon

We would, of course, be remiss if we didn't mention acogedor dc fan speed control for daily usage. It is easy to control the rotation of the motor with the knob. It is made of high-quality electronic components with stable and reliable performance. It can swap the input voltage of the product is within the range of dc. It is easy to wire up, functions as described. It is a very well made controller.

The switch is pretty good for reversing the DC power flow and controls the fan just fine. It is a massive overkill for anything small / mid sized. It is easy to install in narrow space.
