About 12v Rgb header and 5v argb header

[ˢᵈˣ FatCat]

It's hard fighting a future where everything is ARGB stuff, i hate it but maybe it would be better if i can control it
Yes i know i can turn it off .



SO, I dont get it, if my 3rgb fans parallely coneected to 12v rgb header
Can we adjust it usiing Aura aynch?
Or we need the Argb fan things
Any insight what should i do or not do when synch led fans and stuff?

I don't really understand your question.
ARGB lights you can control with data pin. I made a controller for it using RaspberryPi pico (4EUR). Connected to usb port I can decide lights patterns by simple Python program.

RGB connector only allows you to turn lights on/off and change the color.

Which one you want to use and what do you want to control?

12v rgb, all leds are the same color
+12v,-g,-r,-b

argb = addressable, each led can be a different color
+5v, digital signal, gnd

they are not compatible

most mobos have headers for both
when using argb, bios or software has a setting for how many leds to control, max is 1024 in a string (shorter string can do higher refresh rate)

i want upgrade buying new case for my PC, and all that have ARGb fans , BUT, they can sell without the fan, more cheaper, so if i buy just RGB fan, can i control the color using aura sync,

sry man, this fan thing are new horizon for me

so it wont synch with my Motherboard? if iam using 12V

AURA synch - that's from ASUS, isn't it?
Asus motherboards have both connectors RGB and ARGB.
You can buy fans separetely and connect to the right header (RGB or ARGB). When you buy fans separetely, prefer ARGB. They look nicer (you have more control over colors and patterns).

I was playing with this fan:
https://gelidsolutions.com/product/stella-infinity/?srsltid=AfmBOoroo4BP0jgqfYHYcQ0mp7cb6qyv03ixR2FJxivJ8tGHqWtLeONx

Easy to to control, both speed of fan and colors around from single raspberrypi pico. (It works also with my AsRock motherbord. It is the chepest of all cheap, so I'm not advicing it as "best" stuff :-).

You should be able to control 3 fans using one RGB conector. They will all show exactly the same color pattern. That's it. (edit: there will no pattern at all, just one color, which can change).

so what is the purpose we using RBG header? i mean my soon to be fan only have molex lol , but looking at top , maybe i should try that Stella infinity

[BurakZG]

you can still decide the color with RGB header.
If you put max allowed voltage on all 3 RGB inputs - the color will be white. You can keep changing that color, but it will be the same color on all LEDs.
With ARGB you can define the color on each LED separetely. Making animations and rainbows :-)

if the header is on the mobo, the mobo controls it

what mobo do you have?

asus b550f strix gaming wifi 2

[_I_]

the board has both
https://rog.asus.com/motherboards/rog-strix/rog-strix-b550-f-gaming-wifi-ii-model/spec/
1 x Addressable Gen 2 header
2 x AURA RGB headers

on the bottom edge of the board, 2 white connectors
3pin (x.x.-.x) is argb
4pin (x.x.x.x) is rgb (and the 2nd is at the top edge of the board)

i get it, i mean what are those lol exactly, what i can i do with that,
so if i buy 3RGB fans, i need connect its RGB to the Aura RGB header right, and if iam using 3Argb Fans, i need connect to 1 A Gen 2 header ?
and whats the difference? only the ARGB we can setting the rainbow stuff? and can that fan synch up with Aura sync or i need buy the ARG ones?

[_I_]

if the fans are argb plug them into the argb header
if they are rgb, then the rgb header

if you plug a argb led/strip into a rgb header it will kill it
which is why the key is on pin 3 of the argb connector

there is no argb 'gen' they are all the same (ws281x led/controller)
asus just uses 'gen' to identify that they are 5v argb, not 12v rgb

there is lots of software to use to control both styles on the board
asus has their own, or 3rd party to do more

the argb fans should come with a splitter or maybe their own controller depending on the fan
might be usb, or plug into the rgb/argb header

the way argb leds work is kinda neat
they are not assigned, but its their place in the string that identifies them
signal is just r-g-b repeating, and stop at the end of how many leds it thinks its controlling
the first led receives r-g-b values, if it gets another r-g-b value it passes it to the next in line
when the signal stops for 1ms, each led turns on to the color it has stored

i have no idea what you talking about, but one way to find out, gonna try those Argb fans , speaking about controller, we use controller if we using like 10 fans or more right, if just 3 we dont need controller right
