Control Freak 5Amp Single Fan Speed Controller
The Control Freak Plug-In is an extremely cost-effective way to adjust the speed of your intake or outlet duct fan with the turn of the knob! Choose the bundle with a temperature probe and you can automate your fans to maintain your chosen room temperature. A great starting point for those looking to take control of their growroom environment.
- Regulates fan speeds for an optimal environment and faster growth rates
- Comes in at a great price – incredibly cost effective
- Plugs straight into a mains socket
- Wide adjustment fan-speed control
- Can supply up to 1150 watts (5 amp)
Please note: though digital fan speed controllers (like this one) are a very cost-effective solution, they may generate a humming sound. This is an unavoidable consequence of using ‘pulse width modulation’ to regulate fan output. We highly recommend SMSCom Hybrid Fan Speed Controllers, which instead use heavyweight transformers and run completely silent.
This fan speed controller is not designed for use with Isomax fans. If that’s your intention, then please take a look at our SMS controllers instead.

How the Control Freak Fan Speed Controller Works
The Control Freak plug-in fan speed controller is a great little piece of kit that allows you to control the speed of your in-line duct fan. The unit plugs directly into a mains outlet and your extraction fan plugs directly into the socket located on the front of the unit. The control on the front of the unit allows the user to manually adjust the speed of the fan and thereby control the rate of extraction.
A higher rate of extraction during summer months is generally good as it will reduce the temperature and humidity in the grow-space. However, during winter months, a fan running at full speed may reduce your grow-space temperature too much. The Control Freak fan speed controller allows you to reduce the fan speed, allowing your grow-space to remain at a good temperature while simultaneously reducing fan and duct noise.
The added temperature sensor very simply plugs into the small socket on the top of the unit. When this is done, the fan speed control on the fan speed controller sets the minimum constant fan speed while a second control on the controller allows you set a “maximum” temperature which when reached will increase the fan speed to full until the temperature in the grow-space has dropped back down again.
The Control Freak can adjust the speed of fans with a maximum power consumption of 1150 watts (current draw of 5 amp).
Using the Control Freak Plug-In
Plug the fan speed controller into a mains socket and then plug your extractor fan into the socket on the front. When the mains socket is switched on, your fan will begin to run. Use the control on the front of the Control Freak fan speed controller to increase or decrease the fan speed as required.
Remember, the fan speed always needs to be high enough to remove adequate amounts of stale air from your grow space, even when the room is cold. If the fan speed is too low, there may not be enough fresh air exchange to replenish CO2 for optimal plant growth. Also, having your fan speed too low may not keep the humidity down enough for good plant growth and to reduce the chances of mould or rot during flowering.
The added temperature sensor very simply plugs into the small socket on the top of the unit. The control on the fan speed controller sets the minimum constant fan speed while a second control on the thermostatic controller allows you set a “maximum” temperature which when reached will increase the fan speed to full until the temperature in the grow-space has dropped back down again.
The Control Freak can adjust the speed of fans with a maximum power consumption of 1150 Watts (current draw of 5 amps). However, it should never be used to control the speed of circulation type fans which generally have their own speed control. Using the Control Freak fan speed controller to control a circulation fan will invariably burn out the controller or the fan itself.
