      They took long enough to respond. Anyone with a fan they can't use an ECM on and doesn't have its own built-in controller, DCC Controls is the way to go.

      It will work on a brushed and brushless fan, it wont work on a fan with an internal pwm

      You mean like this one that specifically states can’t be used with PWM controllers?

      A brushless fan will still have a multiphase inverter and it’s going to get quite pissed off if you connect it to a DCC PWM controller. Perhaps DCC could supply details of brushless fans that work with their controller….

      For those who are interested here is some good information on how brushless DC motors operate and how they are controlled. It’s complicated….

      The brushless fans that are three wire (bat+, bat-, pwm signal input) cannot be used with the DCC (or PSM/vaporworx) brush-type controller. Basically any brushless fan motor that needs a PWM control signal.


      For brushless fans that do not have the logic built in (two wire) there is a very good chance that the DCC controller will work well. It does work on other similar brushless motors such as those used for water pumps. A bit of experimentation would be needed but with a high likelihood of success.


      But, if given a choice, the OEM or Spal brushless fans with built-in logic would be my first choice. They are worlds better than the aftermarket 12v-on brushless fans. Control can be done with an OEM ECM, many aftermarket ECM's (Holley), or a DCC/PSM/VaporWorx stand-alone brushless fan controller.

      Ehh, that was what they sent me, that's all I can do. I moved on to ECM control years ago so can't say one way or the other.
