12V RGB fans header

[soulven90]

Hi I currently own a CM Q300P case and it comes with 2 RGB LED fans and a splitter, now its not listed on the spec page but I think they are 12V non-addressable RGB LED fans. Now my questions are:

1. What would happen if I plug it into a 5V aRGB header on a new MOBO I plan to purchase (ROG STRIX B360-I GAMING)? Will it light up/spins?
2. If I now don't care about the RGB LED and I just want them to spin, can I plug the splitter into, saythe 4-pin chassis fan connector?

Thanks.

The rgb probably won't work if you use a 12v strip on a 5v header. The fan should work if it's plugged into a regular fan header. Is there a seperate rgb plug on the fan or what?

The RGB pins don't provide any power to the fans at all, the fans will have 2 connectors, one for power and a second for RGB. You can have the fans powered normally and leave the RGB unplugged and they'll operate like normal fans.

 

You cannot connect an RBG connector to an aRGB header, they're pinned differently.

The 3 pin header is 5v

The 4 pin is 12v

Yes

Each fans actually comes with a 4-pin connector (I assume its 12V as its not mentioned in the product spec page) and the case comes with a splitter so that I just need to plug the splitter into the MOBO and both fans would light up and spins). Now I have 2 options: 

1. Get the MOBO mentioned above but it comes with 5V aRGB header which won't work at all ?
2. Get another MOBO that have either a 12V RGB 4-pin header OR no RGB header at all and I'll plug the splitter into the chassis fan connector

If your fan comes with one 4 pin connector that's probably just the power for the fan. The rgb might be automatic or something. What fans are these?

Incorrect. Each fan will have 2 headers...

 

Either a 3 pin or 4 pin PWM connection that provides power to the fan and either a 3 pin RGB or 4 pin aRGB connection that provides power and data to the RGB.

 

Can you take a picture of the header?

Here's the thing it comes with the case and I couldn't find exact specs of the fans. http://www.coolermaster.com/case/mini-tower/masterbox-q300p/

Those are 12v RGB fans, they'll have 4 pin PWM power headers and 4 pin RGB headers and will be compatible with your X300 series board.

The splitter looks like this. I don't have a X300 series board as I am planning to buy a new one now. As mentioned my options are: 

1. ROG STRIX B360-I (cause I loved the onboard WIFI) but it comes with a 5V aRGB header which won't work with my splitter, correct?
2. A cheap board like ASUS PRIME H310M-A with 0 RGB header whatsoever, but I can plug my splitter onto the 4-pin CHA_FAN header? (just for the sake of learning, how would that work? I learnt that RGB fans pins structure is something like 12V/R/G/B but the 4-pin CHA_FAN header is actually ground/12v/tach,pwm, no?)

EDIT: They dont have another 4pin PWM header as I believe RGB header already carries 12V on the first pin then 1 pin for each RGB

They're RGB LED fan that comes with the case Q300P and I believe they can draw power for the RGB header on the motherboard which already carries 12V on 1 pin and 3 other pins to carry R/G/B

They do.

 

It just so happens I have an RGB fan lying around...

 

 

See how it has 2 wires and 2 connectors on it. The left hand side one is a 4 pin PWM connector for fan power, the right hand side one is the RGB connector.

 

You're correct in that RGB does carry 12v but it does not power the fan, the fan has its own separate power. FTR aRGB actually uses 5v and not 12v.

 

You can run the fan with no RGB and you can run the RGB with no fan. I currently have 6 RGB fans in my case and another 3 aRGB ones lying around doing nothing (because my current board doesn't support aRGB).

Hi yes you're right, I missed that cause they're connected to a 4pin Molex splitter.
