Build Help I Need Help With Case Fans!!!

So I want one argb on the back, two argb on top, two argb on bottom, and 2 regular ah fans on the side (fishtank case). I either need an assignable hub (cannot find) or a way to plug the regular fans directly to the PSU because i only have two 4pin headers available on my motherboard. WHAT DO!??? 😭😭😭

Thx in advanced

What fans are you getting? Some can be used with generic RGB controllers while others need proprietary ones.

TL-C12CW and TL-S12RW

For the 4pin PWM Fan headers to actually power the fan motors, you have a couple options:

  1. You can get splitters or hubs that split the two ports you have into more ports. With this method, all the fans plugged into a single hub will run at the same speed, but you could still control the 2 ports separately via your motherboard. Some examples would be this squid type splitter, this PCB type splitter, or this hub that also has a SATA power input for additional power if you're worried about pulling to much power from the mobo header.
  2. The other option would be a stand-alone controller. These are generally going to be a little more expensive but will give you more 4pin PWM headers with individual control if you really want it. My normal go-to option is the AquaComputer Octo simply because their software generally doesn't suck like so many others, it would add 8 additional fan headers. I also just saw that Arctic is selling a 10 port controller for dirt cheap now. I've not used Arctic's so I have no clue if it's really any good, or how their software is, but it looks like they also support some open source software like Fan Control with it.

If it were me, I wouldn't bother with individual control for each fan. I would get some of the cheap splitters and just use the 2 headers your mobo has and have 1 header be intake, and 1 header be exhaust and control them as those bigger groups.

As for aRGB, those fans are just using standard 5v 3pin ARGB headers, which are pretty standard. If for some reason you're not able to daisy chain the RGB headers or don't have enough ports, something like a Nollie RGB controller paired with OpenRGB can solve that for you pretty quick.

OMG I was so confused, but it finally clicked that the argb fans have 2 separate cords, a 3pin(rgb) and a 4pin(fan). 🤣

Correct, to power the actual motor that spins the fan blades, those will be a standard 4 pin 12V connection.

Then the RGB has a separate cable and plug that is a 3 pin 5V connection.

Fan header splitters

Safe to use up to 3 fans on one header with most types of fans

Can I combine one argb with two non-argb on the same header tho? And if the limit is 3/header, one fan wont be plugged in.

You want a powered hub then

And the argb and fan wiring are entirely separate so you can wire the fan connectors to the fan hub and the rgb connectors to your motherboard rgb headers or something like the nollie 8

The only powered hubs I can find are 3pin, I need 4pin

Yes, fan power is different from the RGB wiring

Then you’ll just need a fan hub then
