Cooler master hyper 212 rgb black edition change color

4 pin connector for the leds is RGB 12V, 3 pin is ARGB 5V.

Both fans had a 4 pin 12v to mobo, and 3 pin for led - conenctors were 100% Identical, I unhooked them, installed the heatsink and reconnected in the same positions --- I'm sure it's something really simple as far as resetting the controller to "see" the new fan or something, I'm just not sure - I've never dealt with argb (rgb) fans before. My old system I used cold cathode tubes, and this only has RGB as what it came with, but it bugs my OCD that they don't work together yet lol.

Both the old fan and new fan have this exact pin setup for the fan and led connections. This is the old one (new is currently installed)

That voltage is for the fan motor, and all standard PC fans are 12V. LED voltages are separate from this, and there are both 5V and 12V standards. Show a pic of the RGB connector from both fans?

Edit: ah, yes, that fan label does state ARGB. The stock case fans are most likely not ARGB, and the controllers will then not be compatible. I would assume your motherboard has an ARGB header? Plug it in there instead.

That ARGB fan is what I removed from the cheap cooler they used - but it synced perfectly with the case lights. The pinouts were exact so I tried to reconnect exactly how it connects --- I know the motherboard supports the cpu fan and I can hook it directly into the motherboard - But I was hoping to control it along with the case fans so I can shut them off at night or change the colors in one move versus having to get into the bios. I'm almost certain the fan will work--- just need to figure out the right configuration with wiring or "learning" the controller to accept it or vice versa.
