PWM Fan Speed Control Module, DC 12V 3A 4 Wire with Two Probes, Controller, Automatic Temperature Controller NTC Sensor for 3000mA

It is a PWM 4-wire fan temperature controller. The automatic temperature controller of the fan speed control module can automatically adjust the fan speed to the actual temperature The PWM fan speed control module only supports 4 wire PWM fans, not 2 wire and 3 wire fans. DC12V four-wire fan temperature and speed controller, digital display of temperature and speed, supports the low temperature shutdown of the fans within 3A (can directly shut off the fan power supply) and supports the reverse clocking of the fans PWM fan speed control module made of high-quality materials, robust and durable, convenient to cable This PWM Fan Speed Control Module only controls the speed control of the fan, which is controlled via the four-core standard PWM signal. The signal specification is 25 kHz, 5 V. Conventional chassis, CPUs and many server four-wire fans support this, but the speed control of 2 or 3 wire fans cannot be controlled with this Temperature measurement range: -9.9 degrees - 99.9 degrees Temperature measurement error: 0~50 degrees less than 1.2 degree; other temperature range below 2 degrees. If the temperature is too low, the fan may stop running
