DC 12V PWM Fan Speed Controller, Four Wire CPU Chassis Fan Temperature Governor Module with Alarm Function for PC Cooling

DC 12V PWM Fan Speed Controller, Four Wire CPU Chassis Fan Temperature Governor Module with Alarm Function for PC Cooling

• [PRECISE TEMPERATURE CONTROL] Achieve accurate temperature settings with advanced PWM technology, ensuring optimal cooling performance for your PC. The controller maintains stable fan speeds even under varying thermal conditions, perfect for high-performance computing.
• [4-WIRE FAN COMPATIBILITY] Designed exclusively for standard four-wire chassis and CPU fans, this controller ensures seamless integration with PWM-capable fans. Avoid compatibility issues with non-PWM fans, as it only works with 4-pin connectors.
• [DUAL CONTROL MODES] Switch between manual speed regulation and automatic temperature-based control. Customize your cooling strategy with flexible settings tailored to your PC's thermal demands.
• [RELIABLE FAN FAILURE ALARM] Equipped with sound and light alarms (buzzer included) to alert you of fan failures. The alarm automatically resets when the fan resumes normal operation, ensuring continuous monitoring without manual intervention.
• [INTELLIGENT SPEED ADJUSTMENT] Automatically adjusts fan speed based on temperature thresholds. Operates at minimum RPM when below the set temperature and ramps up to full speed when exceeding the threshold, optimizing noise and cooling efficiency.
