Thanks for the information! I decided to take a risk and did some manual testing on the fan RGBs myself, and yes it is really the WS2812B LED strip. Works exactly like how I used these strips for other purposes, just that my Asrock MOBO won't control it. I think it's due to the software/firmware issue of the native RGB controller though. For reference if anyone wants to know the exact pinouts of the RGB headers on the HD140 fans Top View (the protruding part that clicks/latches is on the top) (not sure how to describe) https://imgur.com/a/sy9ccfq 1. 5V (Red wire) 2. Data Out (This can be left unconnected or to the Data In on the next LED strip). (Green wire) 3. Data In (Data out from computer/source connects to this) 4. GND (Black wire) *PS terrible formatting of post - and after more testing I realised that the Data In and Data Out pins were actually reversed (probably a nifty little trick to prevent users from using standard ARGB ports on their mobos)

Hey there! I'm new to this forum and I recently built a new rig with two Corsair HD fans. The thing is though, I didn't buy the twin/triple packs that come with the controller. Now i'm stuck with lightless fans, and I'm wondering how compatible these fans are with the motherboard ARGB pins. I've got some experience with Arduino LED strips myself, and does the RGB work the same way on motherboards (for ARGB) as the typical Arduino Data pin? I saw this simple CoolerMaster ARGB splitter that connects to a mobo's ARGB slot, and I was wondering if this could be a possible workaround to my current problem. It'll be great if anyone has tried this before and could shed some light on this.
