I bought this to control the fans in my home brew 1Kw VHF amplifier. The versatility of this board is great with potions that do all I ever wanted. PWM controlled fans are great solution for the task, and this controller makes working with them enjoyable.

I added this to an electronics installation under the dash in my motorhome, so it's an atypical application. That said, I did confirm, the multiple outputs are not all controlled alike. It works very well for the one fan I needed to power, but Buyer Beware, multiple fans may not act as you might initially expect.

Now with seven DIP switches.Function setting switch description (Any setting must be powered on and then can be effective):TFL (number 1): The temperature control channel starts PWM setting, FAN1 starts PWM at 40% in the ON state and 20% starts PWM at FAN1 in the OFF state.T1 T2 (No. 2, 3): Temperature control channel control temperature zone, the specific settings are as follows (need to be used with temperature probe):T1 T2 acceleration temperature Full speed temperatureOFF OFF 35℃ 45℃ON OFF 40℃ 55℃OFF ON 50℃ 70℃ON ON 60℃ 90℃Below the acceleration temperature, it is output with the starting speed signal, and above the full speed temperature, it is always output at full speed.BF1 BF2 (No. 4, 5): corresponding to FAN1 FAN2 stop alarm function switch, when the corresponding open, the channel fan fails and stops, the controller will sound (need to use the buzzer) light alarm, the fan resumes rotation and the alarm is automatically eliminated. If BF1 and BF2 are both on (ON), either or both of FAN1 and FAN2 stall, and the controller will alarm!PF: After this switch is dialed to the ON side, the controller fan control signal is output in reverse to control the reverse timing fan.SY: After this switch is dialed to the ON side, the output signals of the 2 and 3 channels of the controller are synchronized with the 1 channel, and the three channels are temperature controlled at the same time

This product does not actually support three fans. It supports two with alarm conditions and speed control.... but the third fan is just simply DC power it has no speed control whatsoever or alarm features.The product description is exceptionally misleading giving you the idea that this will control three fans when it will not.

I noticed this board utilizes a 78l voltage reg for 12v and figured it could tolerate up to +30 VDC rail. This is true for the controller, but the input voltage is passed directly to the fans. As you may be able to guess, this resulted in the destruction of my 2 brand new Noctua fans. Very sad to say the least....

This controller is great. Much better then the other similar sized ones and more amperage. This latest version gives the option to have all three channels act as channel 1, allowing the load to be spread across the board instead of splitting channel 1, if you wanted all of your fans temperature controlled. Another addition is what’s labeled “ reverse output” which basically makes it operate opposite of normal. So if you had it set on 40-55°c range that would normally kick on full output, it would now kick off, completely. Instead of cooling, it would be working to heat, essentially. It’s an excellent print with textbook soldering.

Do yourself a favor and watch the 15 min video on youtube done by a creator named ColdestMoon. The video is titled "ZFC39 PWM Fan controller".Fan 1 is controlled by dip switch board and thermal probeFan 2/3 are controlled by the potentiometers right next to each connector (10-100% duty cycle)Duty cycle = % of speed of the total RPM of the fanTFL Off: Runs fan 1 at 20% duty cycle when thermal probe is not activatedTFL On: Runs fan 1 at 40% duty cyclewhen thermal probe is not activatedTP1/TP2 controls the start "ramp up" temperature and the highest temperature of when the fan spins up to 100% duty cycleBF1 Off: Does NOT sound buzzer alarm when fan 1 drops below 800 RPMBF1 On: Activates the sound buzzer alarm when fan 1 drops below 800 RPMBF2 Off: Does NOT sound buzzer alarm when fan 2 drops below 800 RPMBF2 On: Activates the sound buzzer alarm when fan 2 drops below 800 RPMFan 3 RPM drop sub 800 or malfunction does not trigger the alarm buzzer

This works great for adding a temp controlled fan to my audio cabinet. NOTE: only Fan 1 header is controlled by temperature sensor. Headers 2 and 3 have individual pedometers. I was able to find a YouTube video explaining the settings.
