Question about cables and fans

[Kaishew]

Hi I’m a bit stumped on whether I did my cables correctly... I have the commander pro and rgb hub and was watching a video on YouTube and it looked as if I can’t have 6 fans because one of the cables coming from the pump reservoir goes into the #6 slot of the Corsair commander pro fan port?

 

How is it thst I see some people are able to fit 6 fans into their case even with the Corsair hydro x kit in?

 

I also only have it for the CPU for now since there’s no waterblock for my GPU at the moment and I was wondering if it was ok to connect the CPU waterblock to my reservoir which then connected to the LED port of my commander pro.

 

I wish I was able to have my 6th fan but idk where I’d place the cable since the 6th port on my commander pro is taken up by the reservoir cable... is there another way to this possibly? Thank you!

All you need for the fans is a simple PWM splitter so you can pair two of them. You won't need independent speed control for every fan in the system and those on the same radiator surely will be on the same profile.

 

In the CUE lighting set-up for the Commander Pro, it will give you options for the Hydro X daisy chain. You will be able to tell it XC7 -> XD5 and then later change it to CPU->GPU->pump/res. The Hydro X chain is useful because you can both set each LED individually or they will automatically link between themselves (color waves passes from CPU to GPU to Pump/res, etc).

Oh so when I use the splitter do I then connect the 5th and 6th fan onto the cable and plug that into the 5th fan port?

Or 1+2 or 3+4. It doesn’t really matter which fans you pair up, but preferably they are the same type.

You may also find that controlling the speed of the pump is pretty useless, and may want to run it at a quiet fixed speed. usually, somewhere around the 60% mark you're good to go.

So you could leave the pump PWM on the motherboard CPU fan header for example, and have fun with the CoPro for controlling what needs to move : fan speeds.

Ahh gotcha thank you!

Can I leave it connected to the copro but adjust the speed to 60 and leave it at that? Since I’ll be having the splitter cable I might as well have access to adjust the pump AND all 6 fans if possible!

You want the pump connected to it's own PWM header for control, one way or another. I use a fixed pump speed as well, but giving it a control header on the Commander lets me toggle between various fixed speeds or whatever curve with a mouse click or two. The pump only has to be on #6 in order to use the Corsair Hydro X presets. You may or may not want them, but it makes sense to put it there (vs 1-5) so you have the option. It will work from any PWM control header while getting it's power from a molex connector.
