Circuit Board Size: 50mmx43mmx13mm(LxWxH)
Positioning Hole Position: 44mmx37mm
Hole Diameter: 3mm
Working Voltage: DC12V
Bus current: 9A(Max.)
Temperature Probe Parameters: 50K B=3950
Stall Alarm Minimum Speed: 700-800 rpm
Fan1 Channel PWM Setting
TFL = OFF : FAN1 pwm output range is 20%-100%
TFL = ON : FAN1 pwm output range is 40%-100%
Please refer to Figure 5 for the temperature control settings of the Fan1 channel.
(Note: the above range is only the PWM range, the actual fan control effect will vary according to different fans)
Fan2, Fan3 Channel PWM Settings
Control the pwm of Fan2 and Fan3 channels respectively through two potentiometers on the circuit board.
The pwm output range of FAN2 is 10%-100%
The pwm output range of FAN3 is 10%-100%
Buzzer Alarm Setting
BF1 and BF2 are fan stop alarm functions.
BF1 switch : FAN1 stop alarm function switch
BF2 switch : FAN2 stop alarm function switch
(If BF1 and BF2 are both turned on (ON), the controller will alarm if any one or both of FAN1 and FAN2 stop.)
Package Included:
1 x DC 12V Fan Speed Controller
1 x DC female wire 20cm

Did exactly what you said it would and I was able to run the fans in my son cpu.Perfect

I connected 1 PWM fan that I wanted to slow down to make it quieter (there is lots of cooling capacity). Connected the 12V supply, but neither dial will change the fan speed at all, it still runs at full speed, no matter which fan port I plug it into.

Description shows version 1 which only controls FAN1 using temperature probing, but some of the pictures show version 2 board which can have all three controlled by the temperature probe.I knew I was getting version 1 and it works like it should and works for my application.Just be aware of what you are getting, other than that works perfectly so far.

I've been running this with 2 silent fans on my server unit for almost 6 months. The multiple speeds and alarm have saved me a bunch in power and while nothing has failed you can hear the alarm trigger when you first start it up until the fans reach their rpms. Would recommend buying or 3d printing a case for it but works great as is. Within a year this will save me money over the previous 120v system I had

Some fans need opposite logic for speed control - eg control line goes to negative more or positive more for faster speed. Some fans I tried it would slow down when hotter, so I had to change to a different fan.It has a convenient range of settings and documentation is fairly clear.
