ZFC39 PWM Fan controller

I bought a ZFC39 PWM Fan controller for a project but found little information, this is my experience with this device and hopefully it will give some help for others who are using it. Links below for the pulse width modulation controller and 4 pin Fan as used in this video.

Thanks for the tutorial. My application is shoehorning an EVGA GTX 1080ti FTW3 heat monster into an old Z420 workstation. I'm 3D printing some parts to duct 3 fans to force-cool onto the CPU and the GPU and this controller will fit the bill. I was hoping all the fans were temp controlled but I think it's still going to work in the confined case. Once again thanks for the video.

Thanks very much! Well done on explaining this fan controller.

Thank you, I picked one up on a whim, and your video was the first I find when I started looking for a manual to figure out the dip switches.

CONFIRMED!! ZFC39 Version 2 will control all 3 fans based on the thermocouple temperature, if pads SY are soldered or bridged. Note also that in Version 2.0 the 'Fan Stall' alarm is disabled during startup, eliminating that annoying beep during startup. I am also experimenting with adjusting the 'Accelerating temp' and 'Full Speed Temp' values by placing resistors across the thermocouple.

Thanks a lot for the well articulated video.I just bought this item to control the fan which I am planning to use to cool my hot running AV Reciever and I was also not very clear about the operational instructions given by the merchant. This video is a God send. Thanks again!!!

I have this fan controller board and had no idea how to use it. Now I do! Thank you.

Great helpful video! Well done. The manufacturer should pay you a stipend for helping them!

This is awesome bro! I have ordered did from grandado a few weeks back. Could not find anything else themprature steered pwm controllers with a normal 12v connector. I am actually impressed by the functionality, I ordered it for a cabinet fan which I use Noctua for. Good to see this product already revieuwd

You absolute legend. Thank you for taking the time to make this video 🙌

Actually, you can jumper signal pwm pin from fan 1 and cut the connection to potentiometer on fan 2 and 3.

Just received this board and if not this video .... You helped me A LOT with this video!!!

Very useful video, I've been looking for pwm controller for pc fan out of case use, and not only I've found it here but yet for everything explained... Hard to find any information on web... Keep doing your work mate, thank you

Great video. I'm just waiting for my parts to be delivered to add cooling fans to my Dometic fridge. Based on the supplied thermistor characteristics, by adding a 500k multiturn pot in parallel to the thermistor you should be able to bring down the "starting" temperature. I've calculated that a resistance of 91k should effectively give you a temperature range of 25 - 38 degrees C or 68k to give 20-36 Degrees C. My reasoning regarding using a 500K is that if it doesn't work, 500k would bring the curve characteristics almost back in line (if that makes any sense)

Greetings from California.Thank you for the instructions. Once I received the above item, I was like what are those DIP switches, until I viewed your video. Bless you, buddy. Have a nice day. 93s.

The Arctice cooling fans are good fans. You picked a good one for a good price!

[DesmondsDonders]

Nice one Dan. I went through similar when I built one for our last caravan. Only a twin fan board but very similar otherwise.

What did you use as a power supply? A simple wall wart or a switching power supply/something more substantial? Would you recommend a wall wart for it?

I have been doing some experimentation for cooling the fins on the back of a thetford motorhome fridge/freezer using one of these modules and an arctic P14 fan ( more efficient and quieter than the F range fan used in the video ). Found the fan to be noisy a lower speeds, I think due to the 'pulsing' of the PWM causing vibration. I think the PWM signal is perhaps based on a low frequency based signal ?. I was about to abandon this module when I tried fan 2 port and turned up the speed to full, then lowered the power supply voltage down to 6 - 8v and found the fan to be absolutely silent at these lower voltages with no vibration at all !. Also found even at 6v -8v the fan still has surprising torque at very low speed and easily kickstarts itself if stalled manually. Perhaps the answer is to regulate the speed by changing the supply voltage but I dont know how to regulate the voltage automatically depending on temperature ? Any ideas anyone ?. One thing I forgot to mention is that I use a small buck module to regulate the supply voltage to 12v ( adjustable ) as the motorhome '12v ' supply varies quite a lot from 12v to 14.8v .

The only good explanation in whole internet

Great video! I've just received mine and this tutorial will be invaluable 👍👍
