Can I use ARGB fans AND strips on the same splitter cable

[Nick-1200]

I'm building my next build soon but am unsure about a few things. I want to use the Asus Aura ARGB ecosystem using the ROG STRIX Z390-F GAMING motherboard. The only problem is the motherboard only has one 5v ARGB header.

I plan to use ARGB fans and ARGB strips, could I connect a splitter cable to that 5v header and connect the fans and strips to the splitter cable? Or do fans and strips need to use different headers or channels?

Splitter works as long as you don't overload the 5V RGB header on your MoBo by connecting way too many items to it. How much it can take, that is written in the holy bible of PCs (aka your MoBo manual).

Okay, the manual reads:

"These connectors are for individually addressable RGB WS2812B LED strips or WS2812B based LED strips"

"The addressable RGB header supports WS2812B addressable RGB LED strips (5v/Data/Ground), with a maximum power rating of a 3A (5v) and a maximum of 120 LED's"

Two more additional questions:

1 - It only mentions LED strips in those quotes, does that mean I can't connect ARGB fans to that header, only ARGB strips?

2 - does that mean the header can only power a total of 120 LED's (e.g. 3 products that contain 40 LED's each) even through a splitter cable?

That mobo has ONE ARGB header, limited to 3.0 A for all the items connected to it. That includes lighting strips and fans. Fans containing ARGB lighting devices in them are just another form of "lighting strip". So yes, you CAN power and control all your ARGB devices from that one header using RGB Splitters. BUT you MUST adhere to the 3.0 A total current limit. And do NOT go by the "120 LED's max" guideline. That is just a way to simplify the limit, and the REAL limit is the Amps number. So find out what AMPS each of your devices can pull and make sure the total does not exceed 3.0 A. For fans, make sure you distinguish between the amps used by the fan MOTOR which do NOT come into this limit, and the amps consumed by the RGB lights in the fan that ARE the important part of your calculation.

Thank you both, very helpful and informative answers!
