Control Freak 7A Dynamic Frequency Fan Controller – 90-Speed Silent Fan Control

The Control Freak 7A Dynamic Frequency Fan Controller is the upgraded version of the most popular hybrid fan controller on the market. Unlike standard AC fan controllers that clip or distort waveforms, the Control Freak changes the frequency — resulting in silent operation, longer fan life, and significant energy savings.

With 90 fan speed settings (10–100%) and adjustable bandwidth (hysteresis), it gives you precise control over your growing environment. Run both an extractor and intake fan from a single unit, and dial in exactly the temperature range you need.

Key Features

• Dynamic frequency control — no buzzing, no waveform clipping
• 90 fan speed settings from 10% to 100%
• Adjustable bandwidth (hysteresis) for tight or smooth temperature control
• Two sockets — run extractor and intake fans simultaneously
• Energy efficient: power use drops proportionally with fan speed
• Extends fan lifespan by reducing mechanical stress
• 7A rating for higher-powered fan setups
