Converting Addressable RGB 3-Pin To 4-Pin

PolygonGTC

I've got an MSi X399 Gaming Pro Carbon motherboard with a 4-pin addressable RGB header (CLK/DATA/5V/GRND). I've also got an Enermax Liqtech TRII which uses 3-pin (5V/DATA/BLANK/GROUND). The controller for the Enermax is garbage and I would prefer to control it with the motherboad as I'm trying to do a static color and the controller is making that difficult. Now, is there an adapter to convert between the two or can I just make my own cable that eliminates the clock signal and move the 5V back to the first pin?

Here's a picture for reference. I am NOT talking about a standard RGB header (12V/R/G/B).

3 pin: WS2812B

4 pin: SPI (WS2801) (guess)

 

What could decode ws2812b and send out SPI? a µC like those Arduinos or STM nucloes.

I was worried the signals would be completely different. I'd rather just turn it off. I don't care enough to go to that extent.

Check your manual to see if you can configure those pins. Sometimes they have that option.
