KNACRO DC 12V PWM PC CPU Temperature Controller Board - 3-Way 4-Wires Fan Speed Controller with High-Temp Alarm

Description: Intel standardized four-wire fan control protocol, supports all standard four-wire interface chassis fan and CPU fan control, while more than 95 percent support violent fan speed control, three-way independent control of different functions, with the way temperature shift and two-way stall detection alarm function (with accessories), the largest single-channel support 12V5A fan, the entire board supports up to 12V9A total current input. Dimensions 6038 Non-standard anti-timing fan (reverse adjust speed) Features: Board size: the length and breadth 2.0 x 1.7 x 0.5inch/50mm x 43mm x 13mm, the positioning hole position 1.7 x 1.5inch/44mm x 37mm, 0.1inch/3mm diameter Operating voltage: DC12V Circuit load capacity: maximum current per output 5A, the bus currents up 9A Output Range: The first channel 20% -100%, or 40% -100% (TFL = ON) 10% -100% of the second path and the third path Note: The above range only PWM range, the actual fan control effect will vary depending on the fan. Temperature probe parameters: 50K B = 3950 Thermostat temperature zone error: error depending on the temperature probe, generally 3-5% Stall alarm minimum
