Hey guys!

So, I'm building a new computer soon and I had my Cooler Master MB500 case delivered today (this is the only component I have for now).
My mobo will be a Gigabyte Aorus Pro Z390.

When I opened it, I saw 6 fan cables connected to 2 splitters:
  1. https://prnt.sc/r2kfhc - three (labeled) cables connected to a 4-pin end, is this RGB?
  2. https://prnt.sc/r2kfke - three cables connected to a 3-pin end, I guess this is power? If it is, will I be able to control the fans' speed somehow, with it being a 3-pin cable?
  3. https://prnt.sc/r2kfo7 - a 'cleaner' look at two sets of cables
  4. https://prnt.sc/r2kdz4 - an RGB controller that came with the case

Being a complete noob at this... I have no clue as to what the heck I should do. :D
The manual doesn't help as I can't find how many amps I can attach to the fan headers, nor do I understand the terms (LED strips, extension cables...).

Where do I plug the 4-pin and 3-pin cable ends?
Do I have to use the controller or will I be able to control RGB through Gigabyte's software when I connect everything to my mobo (if possible)?
Is it OK to have 3 cables in one splitter, connected to one fan/RGB header?
 
First is RGB and will connect to the RGB controller. Second is power and can connect to the motherboard through a fan header.

you can plug the RGB directly to the motherboard if it has an RGB header.

personally I’d plug the fans into their own headers if you have enough and maybe run two per header at the most.

Thank you for a quick answer!
Could you please take a look at this screenshot of the manual:
https://prnt.sc/r2kmrb

At the bottom left and upper right corners, there are: DLED_V_SW1, DLEV_V_SW2, LED_C1, LED_C2, D_LED1, D_LED2. Which ones should I connect the RGB cable to?

As for the fan headers, I guess they are those SYS_FANx parts, right?

Thank you so much! I'll connect the 4-pin LED cable to LED_C1 (following the little 12V triangle indicator), and I'll check how powerful (or not) my fans are. If they're weak, I'll leave them connected in a 3-to-1 splitter and just plug the 3-pin cable in one of the fan headers.

Hope I don't fry anything! :D

LED_C1 and LED_C2 look like RGB controll. The D_LED seem to be addressable slots. Sys fan slots are for case fans
Hi I know this is an old thread however I’m having a similar problem. My case is the H500 and the RGB is a 3 pin. So can I plug into the 4 pin on the motherboard leaving 1 empty? Although, my second fan would not reach. So I thought to use the included RGB controller. It also has 3 pins so could I plug that into the 12V LED_C1 and C2?

Can you be more specific about the exact thing you are trying to plug into this 4 pin?
The cord I’m trying to plug in has 3 holes. I want to plug it in wherever I can on my motherboard. I have both a 4 pin and one with 4 pins with a pin removed (so 2 pins then a empty pin then 1 pin). So I need to plug it into the 4 pin because it would not fit onto the 2 pin/empty pin/1 pin. The 4 pin I want to connect to is a 12v RGB. The cord I want to plug into that is apart of a controller for 2 200mm RGB fans. A YouTube responded to my question on his video and said that I should just plug it in from left to right and leave a pin not plugged in, is this right?

There are different connections. RGB is just going to power the RGB of the device plugged in.

ARGB is addressable, meaning it’s can change colors, this will be for RGB that can change colors versus something that is just one color.

You can plug a regular RGB into the ARGB and it will power it just fine.
