How to connect built in case fans

[jh01]

I am trying to built my first pc. But I am very confused with all the cables from the built in rgb case fans. The case is DeepCool MATREXX 50 ADD-RGB 4F. There's a sata cable which I connected. But that only lights up the fans, they don't spin. Am I missing something?

did you plug any of the fans cables into anything or only the rgb cables

There's an RGB cable, and a power/PWM cable. If the fans are PWM, it will be a four pin connector. If they're not, it will be a three-pin. Look for a header on your motherboard that says "SYS_FAN_1", or "SYS_FAN_2", or any other number. Plug the connector into the header, ensuring you line up the plastic rails with the connector.

There's a cable that says "main". You mean that one? Also my motherboard says CHA_FAN. Its a asus rog b450-f

Yeah, I mean that one. CHA_FAN is the same thing, it just means "Chassis Fan" instead of "System Fan".

Ah thank you. As for the cable, you mean the cable that says "main"?

Yes, should look like this. It might also have 3 pins instead of 4.

Yes. That is a 3-pin connector. You can plug it into either a 3-pin header or 4-pin header, as shown below.

If I plug the cable in, the rgb stops working and they don't spin

Hmmm, that's really weird. That 3-pin cable looked a little funny, it's possible the case came with a proprietary fan connector that it requires to run. Is there anywhere in the case where you see a little box that the 3-pin might be able to plug into?

See pics. It was connected to that other cable, which went to what I think is the fan connector

Try connecting the main cable back into what it was plugged into before, and see what that cable goes to. It might very well not be plugged into anything at all.

I did that and the cable goes to here: (thats why im confused why they don't spin)

Maybe try going into BIOS and see if the fans are set to zero-RPM? They might not spin up on boot if they have been set to not do anything until the CPU reaches a certain temperature.

Do any other wires come off that white piece that you plugged the cable into? If it's a controller for the fans, it probably needs plugged into one of the motherboard fan headers. The motherboard would tell the controller how fast to turn the fans and the fans would (should) listen.

Oh I gotta first finish the built then. I previously had a different case but I switched to this one. I just wanted to test to see if fans spinned. I'll update when I'm done and able to check the bios

Yeah one sata cable which I connected. It has a sticker on it which says unplug if connected to motherboard.

Anyone has an idea?

Sorry, I ended up getting busy with work and forgetting to come back.

What does the rest of that white controller look like, and what other cables come off it. There is the Sata power connector, and then there should be one that looks like a fan cable.

Like that, but it might also only have 3 pins in it.

Hello,

 

Each fan will have two sets of wires: one is for ARGB lighting, the second is to provide the fan power to spin. The connector in the picture you provided with thehad 3 pins and the little wings on each of the the side (JST connector)  is for the ARGB lighting. It sounds like you had that wired up correctly, initially. The second set of wires that come from these fans are the DC power wires that have a 3pin connector as well, but the connector should look like the attached picture.  The DC fan cable from each of the 4 fans needs to be plugged into the included splitter; wiring of the fans to this splitter might have already been done at the factory. With all the fans plugged into this splitter, you would need to plug the single side of the splitter into a Chas or Sys fan header. I also included a picture of the included splitter below. That should be all that is required to get those fans spinning. I hope this helps.
