Key Features

• Crystal-Clear Real-Time Display: A 4-digit high-brightness LED display presents live temperature readings and fan speed data at a glance — no extra tools or guesswork needed.
• Stable PWM Fan Control: Built on a premium FR-4 fiberglass PCB with an integrated control chip, the module outputs consistent pulse width modulation (PWM) signals for smooth, silent, and stable fan operation — no speed fluctuations.
• High-Precision NTC Temperature Sensor: The included NTC probe (available in metal or insulated shell) responds rapidly to ambient temperature changes with a measurement accuracy of ±0.5°C, enabling reliable automatic speed adjustments.
• Heavy-Duty Construction: Thickened copper-clad PCB with solid solder joints ensures excellent corrosion resistance and high-temperature tolerance for long-lasting, dependable performance.
• Easy Manual Adjustment: A metal shaft rotary encoder knob lets you manually fine-tune fan speed or temperature thresholds with satisfying tactile feedback — quick, intuitive, and precise.
