PC fans are cheap, quiet, and powerful, so they're useful in any project that requires ventilation. With the PC Fan Power Breakout Board, you can power 4 PC fans directly from a 5.5mm x 2.1mm positive-center barrel jack supply, like this one. There's no need to cut and splice wires, just plug the fans into the board with their standard connectors. The board also features screw terminal access to power, fan, tach, and PWM signals, so you can provide or receive power and monitor and control fan speed. Here is an example Arduino sketch for controlling fan speed with PWM.
Use with a 12VDC regulated supply with a current rating greater than the sum of your fan currents. For example, if you want to drive 4 fans that draw 0.25A each, you need a supply that can provide at least 4*0.25A = 1A. See the datasheet for full connection details.
Features:
Four 4-pin PWM fan connectors
5.5mm x 2.1mm, positive-center barrel jack
4-pin 3.5mm screw terminal block with +12VDC, Ground, Tach, and PWM
Board Dimensions: 5.00cm (1.97") x 1.63cm (0.64")
Mounting Hole Spacing: 2.26cm (0.89") x 0.762cm (0.3")

Great Product
Great product, used on some test fixtures and they work perfectly. Convenient way to wire up some fans.

Nice product
Yeah, this product was exactly what was depicted in the ad. Very nice. The product was quickly shipped and arrived in nice shape. I wish the package included a bit (some, at least) of documentation describing how to attach the fan plug. Although this step might be basic for many (and even I figured it out), it would be more clear with a bit of guidance and description. But again, a very nice product.

Thanks for the feedback, I'm glad it's working for you! I added a pic that shows how the connectors are inserted, and I will add a more complete manual and sample Arduino code soon.
