For anyone wondering, i connected the noctua fans to the arctic hub, then the arctic hub into the commander core, and everything works flawlessly. I can controll the speed of the fans, as well as anything else. My PC now sounds like a fighter jet, but my gpu temperature's droped by 10c* so i think it was worth it.

Well, I just realized that actually the controller is powered by a single 4 pin fan header. Anyway since that won't work I guess il just get a proper fan hub. Im think about this one: https://www.arctic.de/en/Case-Fan-Hub/ACFAN00175A It has 4.5a max input, and 1a output for each of its 10 ports's so it should be plenty. When it comes to connecting the hub, I can either try to plug it into the commander core, one of my GPU's fan headers, or if both of those fails, into the motherboard. Thanks for the help, if you have any more red flags please let me know before I fry another pc component xd

I also checked my motherboards chassis fans max current, and it's 1a for every port. I'm assuming it's the same for the GPU as well

So i should try connecting the 4 fans to the case hub, and then the case hub into the commander core? Is that right? The case hub is powered by a sata connector. Similar fans to the pre installed ones (https://www.silentiumpc.com/en/product/stella-hp-argb-120-kit/) Take 0.5a total, the only difference seems to be naming. Since the controller supports up to 5 of them, in theory, it should be able to support these fans. The thing is they take 0.1a from the fan header and 0.4a from the RGB header. I can't find any information about the max output for the headers so hooking up these fans might fry the controller. Should i just buy a new one?

As said above, I'm wondering if it's ok to connect a fan controller from my PC case to one of the fan ports of the commando core. (I'm using the h150i AIO so there are only 3 fan slots left.) (Link to the case fan controller: https://www.silentiumpc.com/wp-content/uploads/2021/02/spc250-spc-signum-sg7v-evo-tg-argb-manual-www.pdf ) I'm planning to plug in 4 Noctua NF-A14 3000rpm IPPC WPM fans to the case controller, and then plug the case controller into the commander core. I can't just connect it into the motherboard case header as I'm going to control my case fan's speed based on my GPU temperature. I also could connect the case controller to one of my GPU's fan headers and control it that way, but I'm not sure if it's a good idea since the fans will rapidly spin up and down when the GPU does small tasks, unlike the commando core which gradually increaser/decreases the speed. If none of the solutions above won't work I also have 2 spare 4 pin fan splitters, so I could probably use them. And no, I can't connect the fans to the commander care as it doesn't have enough power left with the pump and radiator fans running.
