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. If you search for Arduino PC fan controller, you will get many, many hits.

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.

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. Add to cart.

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.

Controlled by a PWM 4-Pin fan connector ensures this fan will only run at the speed needed for your needs. The document does not provide the wire colour scheme however. Let us know and we'll try and match it! Add to Wish List Add to Compare. So I tried the yellow wire normally a tach wire on most fans and oddly, it shut the fan down. Cryptocurrency has taught me to love math and at the same time be baffled by it. Welcome, Guest. I tried switching the position of the blue and yellow wire respectively. Author Topic: How do I drive these Delta fans with varying speed? Just fill out this simple form and we'll see what we can do for you. One thing that I have read is that there is no need to add a mosfet to control the speed of the fan as there is already the PWM wire, wherein control speed of the fan can be controlled through it. You have already demonstrated that by grounding the yellow wire PWM input the fan will stop spinning. Only registered users can write reviews.
