I'm currently working on a source code to control the speed of a fan through a potentiometer in arduino. However, the code does not work and the arduino only runs the fan to full speed. Would really appreciate some or a lot of help as this is for my thesis and the deadline is nearing like only a few days left, still have to do the "paper" :. I even used put search it with quotations marks and still can't find its specs for the wiring. Is the blue wire really for the PWM, then yellow for tacho output? I don't think the fan is damaged as well so i really need help.

Author Topic: How do I drive these Delta fans with varying speed? Read times. Hello everyone, I have recently obtained a box of like 30 or so delta fans from a source that shall remain unnamed for now. I thought they might be the standard yellow tach and blue PWM wires of a standard PC fan, but they aren't, I terminated them in a 4 pin fan header and the fan ran at full speed. So I thought maybe my dell test motherboard was being So I tried the yellow wire normally a tach wire on most fans and oddly, it shut the fan down. So I figured maybe delta just switched the tach and PWM colors around, so I did the same, and the fan didn't move at all when connected to my dell testbench. Then I tried voltage controlling it, it was still pretty fast at 7v and wouldn't even move at 5v, so voltage control seems unlikely. Any ideas?

Would really appreciate some or a lot of help as this is for my thesis and delta pwm fan deadline is nearing like only a few days left, still have to do the "paper" :, delta pwm fan. I already read this datasheet as well but it does not specify what is the yellow and blue wire for as it is a 3-wire fan model, i guess. Cancel Add to Wishlist.

It utilizes the traditional AFC 7-blade design, features a tach output and like every Delta we stock, uses ball bearings for long life. In addition, it is available with your choice of optional cable sleeving. Skip to the end of the images gallery.

Delta pwm fan

A medium-high speed case fan at x x 25mm. It operates at RPM and delivers air flow of With PWM feature, this fan has the ability to adjust spinning speed to achieve a balance of cooling and acoustics. It's also built to be tough to withstand long-hour operation in demanding environments, thanks to industrial-grade materials and top-notch, high-quality dual-ball bearing.

Fan cable is fully sleeved in nylon Techflex sleeving and Premium Heatshrink, colors of your choice. Hello Take a view to get some information. Please select a wishlist. I already read this datasheet as well but it does not specify what is the yellow and blue wire for as it is a 3-wire fan model, i guess. Pages: [ 1 ] Go Up. It only says that "Blue wire frequency -F00 " but i dont know what that means. Read times. This topic was automatically closed days after the last reply. I can't seem to find any datasheets for the 4 pin flavor of this fan, only 2 and 3 pin versions. Pages: [ 1 ] Go Down. In addition, according to the specification, computer fans are controlled by PWM with a frequency of about 25kHz. Hello everyone, I have recently obtained a box of like 30 or so delta fans from a source that shall remain unnamed for now. I tried switching the position of the blue and yellow wire respectively. You do not set the control PWM pin as an output and it is a bit strange to determine the duty factor. Just fill out this simple form and we'll see what we can do for you.

Add Sleeving to the Fan Cable. I tried switching their places as the speed does not adjust according to the potentiometer. Arduino controlls 12V fan. So I tried the yellow wire normally a tach wire on most fans and oddly, it shut the fan down. Now I'm really confused. Please login or register. See how it can change.
