Don’t make the mistake that I did! I bought the hub and 7 of these fans for an open air Rig. I should had done a little homework before I put it all together and plugging them in. No doubt these fans will move air, but they will also draw more current that the little wire harness can handle. I made smoke in a matter of minutes and toasted the wire harness. I may have missed something but there weren’t any instructions or warnings included. I have no doubt I will be happy as soon as I figure out how to manage the current draw.

    These fans are awesome! I will be ordering more for sure. Great price for the 5 fans and a fan controller/distro unit too! VERY happy with the MASSIVE amount of airflow these things put out. I wish they offered something like the Comidox/Zhyiu Fan Temperature Control Speed Controller Module in the kit. It would make a great addition to the kit at around $10 extra dollars.

    Quick shipping, the product works great. Wish the screws were included but able to make it work. Fans are RIDICULOUS in a good way. I bought 10 for one case setup and realize I can spread them out over a couple of rigs!
