NTC 3950 Thermistor PWM Temperature Probe Speed Controller Board Control Module Buzzer DC 12V CPU Fan High-Temp Alarm Heat Sink

DC 12V fan temperature control speed controller CPU high temperature alarm PWM PC CPU Feature? Support all internal 12V 5A fans, synchronous rectification output, high efficiency! Even high current operation does not require an additional radiator! Multiple fans can be used in parallel (total current does not exceed 5A), support automatic temperature control and air-cooling speed control, temperature control speed has four temperature zone settings, easy to apply to various applications! It can be turned on with the three-wire fan monitoring function (stall warning). Specification? Working voltage: DC12V Circuit load capacity: the maximum current of each output is 5A, and the bus current rises by 9A Output range: the first channel 20%-100%, or 40%-100% (TFL = ON) The second channel and the third channel 10%-100% ( Notes: The above range is only applicable to the PWM range, the actual control effect will vary depending on the fan). Temperature probe parameters: 50K B = 3950 Thermostat temperature zone error: the error depends on the temperature probe, generally 3-5% Minimum speed for stall alarm: 700-800 rpm Function setting switch description: TFL (No.1): The lowest temperature channel PWM setting. When the minimum value of FAN1 PWM is 40% in the ON state, when it is OFF, the minimum PWM of FAN1 is 20%. TP1 TP2 (No. 2, 3): The temperature control area of the temperature channel is explained as follows (it needs to be used with the temperature probe): TP1 TP2 acceleration temperature full speed temperature Close 35?45? ON OFF 40?55? OFF 50?70? ON ON 60?90? When the temperature is lower than the acceleration temperature, it will output at the minimum speed; when it exceeds the entire temperature, it will always output at full speed. BF1 BF2 (No. 4, 5): Corresponding to the FAN1 FAN2 stall alarm function switch, when the corresponding open channel fan fails,
