Cooling Fan Control Boards

Cooling Fan Control Boards are essential electronic modules designed to regulate the speed, temperature response, safety protections, and overall operating logic of cooling fan systems. They ensure efficient heat dissipation, stable performance, and long-term reliability across home appliances, HVAC systems, industrial equipment, and automotive cooling solutions.

Choig provides a complete range of cooling fan control boards suitable for DC/AC fans, BLDC motors, evaporative cooling systems, refrigerators, air conditioners, and industrial ventilation equipment. All boards are engineered with high precision, stable performance, and strict quality control, offering both universal replacement models and OEM customization.

Key Features of Choig Cooling Fan Control Boards

✔ Intelligent Speed & Temperature Control

• Real-time feedback from BLDC motors

✔ Enhanced Safety Protection

• Overload protection

• High temperature shutdown

• Overvoltage/undervoltage protection

• Dry-run protection (for evaporative cooling systems)

• Motor stall protection

✔ Multiple Control Methods Supported

• PWM modulation

• Relay switching

• Triac speed control

• Digital or analog speed adjustment

• Remote control / touch panel UI

✔ Low Noise & High Efficiency

Optimized drive algorithms ensure:

• Smooth start

• Low vibration

• Quiet operation

• Energy savings for long-term use

How to Select the Right Cooling Fan Control Board

1. Fan Type

• BLDC fans → choose PWM/FG feedback boards

• AC shaded pole fans → choose triac/relay control boards

• High-power industrial fans → choose high-current heavy-duty boards

2. Voltage & Power

• 12V / 24V / 48V DC

• 110V / 220V AC

• Match motor wattage & startup current

3. Functional Requirements

• Need multi-speed control?

• Require pump output? (Evaporative coolers)

• Require display or remote?

• Need smart temperature sensing?

4. Installation Environment

• Home appliances → compact embedded boards

• Industrial → metal casing, enhanced heat dissipation

• Outdoor → protective coating, IP rating
