Control Freak 3A Dynamic Frequency Fan Controller – 90-Speed Silent Fan Control

The Control Freak 3A Dynamic Frequency Fan Controller delivers the same award-winning frequency-based control technology as the 7A model, in a compact unit suited to smaller fan setups. It changes the frequency rather than clipping the waveform — meaning fans run silently, last longer, and use less energy.

With 90 fan speed settings (10–100%) and adjustable bandwidth (hysteresis), you can dial in precise temperature control or opt for a smoother, wider range. Two sockets let you run both an extractor and intake fan from one controller.

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
• 3A rating — ideal for smaller fan setups
