hey, I am very impressed with all the fans you have, all those jet fans are on the list of fans in my collection that I have never owned, what amazed me is... ebmpapst DiaForce is the latest model fan, and you already have it, one of the fans which uses quite a lot of electricity, nice bro I really enjoyed your video👌
Thank you! I see that you have quite the collection of fans too. I have a bunch as well, but I chose these as they are the high power ones and are more interesting. The DiaForce is what made me want to do the video, it's quite an interesting fan.
@@neonkev7866Sorry in advance, how do I turn on the EbmPapst 5318/2TDH4P fan? cause I just bought it, and if I just use the +red & -blue cable, the fan won't spin
Great video, and brilliant project too. I've been tinkering with this stuff for several years but I'm no electronic engineer so I've been using discreet components to make a simple square wave generator, and it works very well indeed. I love that you've managed to cram so many features into your project, especially the (oft neglected) option to invert the PWM control signal for fans that like it so! What drew me to this video was the thumbnail image, in which I instantly recognised the Servo fans - I have the 12v version of the G1238B, which is an incredible specimen. I also have similarly bonkers offerings from Sanyo Denki and Delta, for which I've had to search far and wide. :)
Thank you David! The microcontroller design enables you to incorporate any feature you can code and fit in the memory. I’ve built discrete PWM controller designs using 555 timers as well; finally decided to buckle down with some newly learned skills and try to make "the" fan controller I always wanted.
I'd love to be able to make a digital one but it's out of my scope. Interestingly, I have just acquired a Nidec Servo G1238V48BHZP-95 and it runs perfectly, but I can't for the life of me get it to respond to speed control and I'm suspicious it's the frequency (which I'm running just below 5KHz). What freq were you using for your Servo fans? It's nigh impossible to get the datasheets for these puppies...! *EDIT: Never mind, I had the tach wire instead of the control wire. If only the colours were standardized, life would be so much easier!
Thank you. Yes, it would be very effective at cooling you off. Just make sure to wear ear plugs and safety glasses. And make sure there are no small, loose objects behind it before turning on!
Thank you! The wires and PCB do certainly warm up, but I made sure to use heavy enough wires and make the traces wide on the PCB. I did a test on the PCB with my thermal camera and a programmable load. At 10 amps continuous, the hottest spot on the PCB are the input traces where the power comes in. Peak temp is 60C with no active cooling. I added the 5V aux fan output so you can add a small fan to cool the board if you want to run 15 amps + for long times.
Thank you! The 9PC8666X-S001 can only support 3.3 volt or 5 volt PWM voltage. You will need PWM signal up to 12 volts for Diaforce. Diaforce also supports control with 0-10 volts DC voltage (no PWM). Maybe you can make this signal with voltage divider using potentiometer.
@@김규헌-k5l I put all the files for controller and level shifter on my website here: neonkev.com/2023/11/06/universal-high-power-4-wire-pwm-fan-controller/ You can download and order PCB and parts, then solder it together.

@@neonkev7866if you didn't know, Sanyo Denki (San Ace) fans are made in the Philippines.

@@Jeff_FanCollector Hi Jeff, are you using 48 volts DC for the fan?

i feel like i need the sanyo tornado for summer, cos man it gets warm lol, great vid bud

@neonkev7866 I research industrial fans lol, I know all about that. We sent a few things flying from the other end of the workshop
What an awesome project!
Something about fans pulling 100W is always incredible to see lol
Do the wires heat up very much?
Thank you! The wires and PCB do certainly warm up, but I made sure to use heavy enough wires and make the traces wide on the PCB.

San Ace 200, oh I know where this is going!
Too bad you don't have their counter-rotating monster.
Haha yup! Maybe I'm feeling indulgent ill pick one of those up too. The biggest problem is running out of room to store the collection..
good video!!
Can adjust the Diaforce fan speed by 9PC8666X-S001?
Thank you! The 9PC8666X-S001 can only support 3.3 volt or 5 volt PWM voltage. You will need PWM signal up to 12 volts for Diaforce.

I can know the special level shifter circuit buy's URL??

wow thank you!!
I will order on JLCPCB the pwm level shifter circle.
@user-tz9xo4xd1y great! looking forward to a video with diaforce perhaps
