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.

Currently recording uncontrollable four-wire Fan Model Summary:
Delta FFR0612VHE, FFR0612DHE; Dimensions 6038
Non-standard anti-timing fan (reverse adjust speed)

Features:
Board size: 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

The above range only PWM range, the actual fan control effect will vary depending on the fan.
The thermistor senses the temperature and the buzzer alarms when the temperature is high
This accessory has a thermal, there is a buzzer, and then four-way control of the fan, you can connect four 12V fans.

Note:
Please note that the controller is a four-wire PWM fan controller can control four-standardized protocols in line with Intel's four-wire fan.
All 4 lines of the chassis and CPU fan are met, a server with more than 97% can control fan violence).
Unable to control two-wire or three-wire fan, you can not completely turn off the fan!

Package Included:
1Pcs DC 12V Four Wire Thermostat PWM Fan Speed Controller Module
1Pcs Buzzer
1Pcs Temperature probe
