Single RGB fan connection confusion...

[Jose Jeswin]

Hi..I am in the middle of an ongoing Ryzen build...my motherboard is an Asus prime B450M-A which has a 12v rgb header for led strips... I will be using a Corsair Carbide 175R mid tower case for the system...now the 175R comes with a single front 120mm RGB fan..the fan has 2 cables, a 3 pin fan power cable & a 4 pin RGB cable marked 12v and an arrow over pin 1.....

Now i have connected the 3 pin cable to my motherboards' case_fan header and the fan spins normally....but the rgb leds do not light up...can i connect the 12v rgb 4 pin cable to the 12v rgb header on the motherboard or do i risk damaging the mb or fan..

The Corsair Carbide 175R case manual tells you to connect the 4 pin rgb cable to the motherboard header though...

Does this Header work ?
if it dont you might want to RMA.

my motherboards header is the one on the right....my fan cable also is the same..

yes the same header....i still have not connected the fan cable yet...scared about damaging the mb..

It should be able to RGB, i use this as source.

what i am confused about is that most sites/videos show connecting multiple fans and/or rgb splitters to the header......the mb manual shows that the header can output 12v 3 amps...will it burn out a single rgb fan if connected..?

 

[Eskimonster]

No no, it supports up to 12v 3 amps, there is a voltage controller

 

[Jose Jeswin]

so it won't burn out the rgb leds on a single fan?..thank you...that's a relief to hear.. so you mean the mb will control the volts/amps required for a single fan automatically?..

 

[Eskimonster]

And up to 50 LED "strips" even

The headers can power single devices or many. However, as you get into two, three, or more fans/strips, they tend to come with a hub which just uses the signal for rgb, and are powered via SATA or Molex.

thank you eskimonster...i am currently away from home...will update as soon as i have made the connection..

Aha..i see... this is the first time i am working with an rgb setup...thank you sneekypeet..

i had already connected an led strip light to the header during assembly some days back...and the header works...but am yet to connect the rgb fan to the header..

Thank you all for your quick and expert opinions.. will update soon..

I have limited experience with these lighting shenanigans but I think that's only for A-RGB. RGB pin can power more RGB things since they're 12V while A-RGB pin needs hubs that pull power from SATA since they're 5V.

 

[Jose Jeswin]

You mean the ones on the left side right?...my mb has only 12v header..not 5v addressable one..

The 5v header has a missing pin....mine has all 4 of them..

The rgb connectors look the same tho....chances of connecting a 5v cable to the 12v header is very high..

Arrow should match pin 1 on the motherboard RGB header. Mobo should have two types of connectors, 4pin for RGB and aRGB one.

Your mobo has 12V RGB header, you have a 12V RGB connector in your case.

Thank you chomiq..

Thank you chomiq..

Hey, I went through the same dilemma this Saturday, reading manual for case and mobo solved it.

i was completely confused after reading both manuals.....i didn't know rgb components came in 12v and 5v adressable versions...atleast one of the manuals should have mentioned this.....

Really hard being a first timer with rgb components..

I'm actually impressed they've managed to narrow it down to "only" two connectors.

Actually there's four!!! According to MSI B450 Pro Carbon AC I was looking at it has J_RGB (12V 4-pin RGB), J_Rainbow (5V 3-pin A-RGB) and J_Corsair (dunno the specifics but A-RGB pin for Corsair products lol). Then Gigabyte has a completely different 3-pin A-RGB header. Last I checked they ditched it in favour of same 3-pin ARGB header others (ASUS, MSI) use.

And OP you're mistaken. RGB and A-RGB are different things. RGB is like if you have a TV and you can change the color of every pixel to the same color. So the TV is blue/green/red/purple for the whole screen.
Addressable is like more refined. You can set it like RGB but also control individual pixel to output different color. Also make each individual pixel turn on and off.

That's why A-RGB things are more expensive than RGB version of the same.

Example for ARGB:

Don't forget Gigabyte's 5 Pin RGB connector so that the fan can do white. The 3 pin is still a unique design as well.

now i have another doubt...is there any possibility of conflicts between Asus Aura sync and Gigabyte Aorus engine+RGB Fusion?.....i have a gigabyte aorus rx570 4G...

i remember reading somewhere that asus and gigabyte are sworn enemies...and their rgb control software is incompatible with each other..

Aorus engine is already full of bugs..

There are some workarounds to allow that, Cooler Master on their ARGB 3 way splitter has a selection for Gigabyte's 3 pin. Gigabyte did update their boards to allow you to use a standard 4 pin in the 5 Pin header. There are all kinds of RGB accessories you can buy on Amazon (mostly from China) like ARGB frames, cables and splitters.

that's great..thank you kapone32..

No problem

YEP, for more than 1 A-RGB fan you need the splitter cable, as the one from Corsair linked above. No need for controller boxes if your mobo has Aura or similar.
