I have a case with 3 RGB fans but I can't control their speeds, so they run at full speed and they are loud, because I don't have a 5v 3 pin connector on my motherboard and I was planning to buy a new one anyways. Can I connect the fans to a motherboard which has a SPDIF_OUT port, because it looks the same as 5v 3pin? Or could you tell me some AM4 socket motherboards that have a 5v 3 pin connector?
[SOLVED] How to connect?

No. No and no.
You are getting your connections mixed up. The fans and lighting are 2 seperate circuits. The fans are 12v and powered from somewhere and the lighting is most likely 5v. How that gets split up and whether the fans are 4pin ARGB or 4pin RGB is entirely different. Some cases use a controller for lighting, but the fans are constant. Some cases use proprietary single connectors and matching fans (6pin) where power is constant and lighting is controlled.
And absolutely no, you don't use S/PDIF out to control/power fans, that's an audio connector for Sony/Phillips Digital InterFace.
What you'll need to do is backtrack the wiring from the fans, there will either be 2x wires hopefully, one will be power and quite often ends in either Sata or molex splitter or fan speed controller, and the other goes to the lighting controller or lighting hub or splitter.

You may not need a new mobo. Fan speeds are controlled by 2 means. Either a splitter/hub/controller or by a fan header on the motherboard.
If the fans are 3pin, and there's just 2 of them, it's usually safe to splitter them and go directly to the motherboard. If there's 3 or more, that's usually above the 1A rating of any motherboard fan header, so case manufacturers will usually go cheap by powering the fans 100% by a hub/splitter that's molex powered.
Something like This hub can fix issues, it's 4pin pwm control of 3pin fans where the fans are powered by Sata, but controlled by the motherboard pwm 4 pin header (header must be set to pwm mode in bios, not DC or auto)

There are many makers of fans, lights, controllers, remote boxes, etc. There is no "universal" set-up, although there are a few standards they adhere to. For us to really know what you have and how to use it, we need you to tell us the MAKER and if possible a MODEL NUMBER (or name) of the fan and hub and remote set. With that we may be able to find its description and manual, or at least some photos to examine.
The fact that fans have 6 contacts in their connectors is a non-standard desing for sure, and they are intended for use4 only with the Hub you have, and controlled by the remote box that came with it.
IF this set came as part of your case but does not have any clear identification, tell us what CASE maker and model this is.

If your fans have 6pins, they are proprietary to that controller. It means they get rgb and power from the same place. But, the controller hub only controls the RGB, it does not control the power to the fan. As far as I know there are no adapters for that.
There's only 2 possible solutions.
There's only 2 possible solutions.
- Get new fans that are a universal fit, they have 2 wires, one for the rgb/argb and the other for power. I'd suggest for simplicity they be pwm fans. This will eliminate the case controller entirely, but allow the fans lighting and speed to be controlled by software.
- If you have the technical know-how, you could pull the power wires from the 6pin, repinning them with 3pin sleeves, but you'd still need something like the above linked Phanteks controller as those fans will be more than the motherboard can power safely. This leaves the case controller to power the RGB, and the added controller hub to power the fan.

With all the power for lighting and fan speeds in one connector, you can't even use a low noise adapter. I mean there are work-arounds, but not knowing your level of expertise or comfort, I'm just as stuck as you. If you have a couple of headers available, repinning would solve it, splitter 2way to 1 header and single the other.
What's wierd is when I look up your case specs, it has no included fans, not even the 3 rgb intakes, almost sounds like you got a good deal on a special order package. But either way, you have limited options. And yours is not the only case to take this route, there are others who do exactly the same thing, probably getting a serious discount on their fan purchases as a result.
They don't make adapters for most proprietary hardware such as yours, too little demand to be cost effective, so unless you personally (or have someone who knows how + trust) modify the wiring, you are stuck with the noise.
Sorry.
