I received one of these as a leftover from my buddy Shawn’s liquid cooled desktop build. I immediately had issues with it, as my project does not have a motherboard. In my first attempt I fried the controller by reversing the positive and tachometer leeds.
Here is what you need to know about setting these up/modifying the controllers to work w/o a motherboard header to connect to:
Here is a shady image of the TT controller side of the connector in the correct format.
pin 1 = ground (long white stripes)
pin 2 = +12V (no markings)
This image is upside down so you can see the pins. You can also see that I cut off the 5th pin on the now RGB connectors. Once I have the LED controller I will adjust the remaining pins and feed it a ground where the +12V fan power used to be before I cut it off. The remaining LED 4-pin connector is shown on the right.
Here you can see where the controller board is actually labeled underneath the header shield. If I had know to do this first I would not have fried a controller. TT’s forums are also not trying to tell you this info which is why I got involved.
Pictured here is the fan header without its shield installed, just because.
