My first question that came to mind was: How is the brightness of the high flow NEXT output set?
The second was: Why don't I see screenshots of the settings, so that the interested reader doesn't have to ask this question?

Lastly, there is the question of what water block you are using and what LEDs are illuminating it.


If you don't feed us with information, how can we help you?
To your question, if the port on your motherboard can deliver 2A you can do it, if not your motherboard will be damaged!

13.4.USB power supply
The high flow NEXT is supplied with power through the USB connection. In default
configuration, power consumption is limited to a maximum current of 0.5 Amps.
This value complies with the maximum allowed current according to the USB spec-
ification. If a large number of LED is integrated, the brightness is automatically re-
duced accordingly.
Alternatively, the current can be limited to a higher value of 2 Amps by activating
the check box. Do not use this function unless the connected USB port is explicitlyDo not use this function unless the connected USB port is explicitlyDo not use this function unless the connected USB port is explicitlyDo not use this function unless the connected USB port is explicitly

I doubt whether 9 additional LEDs are a larger number, but it could explain the behavior you describe.
Whether this is really the reason can best tell you the support: support@aqua-computer.de

This is an interesting observation.

You could, if you really wanted those lights bright, get a powered internal USB hub as Speedy said.
Personally i have a Farbwerk Nano that i use externally to light my desk edge with 90 LEDs. i did set it to 2 amps and it can run all day like that, despite the spec being 500mA per USB2 port. The ports have to supply at least 500mA, but most can take more than that. The thing is AC have no way of knowing which motherboard supports what so, it's 500ma by default with the option to switch.

To be honest, you most likely don't need the whole 2 amps. I've personally set it to 1.3A and i can't really see much improvement going to 2. results will vary depending on what strips you use and what lighting you use too. white would be challenging

I agree you should not switch the HFN to 2-amp mode if it is plugged directly into a mobo USB2.0 header. I still think that adding a Hubby7 (NZXT also makes a nice internal hub) that is Sata powered would solve your problem. That or get a Farbwerk360.

This makes me wonder about the Farbwerk Nano (FWN) which has a single RGBpx port, USB power only, with the 2-amp option, just like the HFN. The owner's manuals for the HFN and the FWN both say, " In default configuration, power consumption is limited to a maximum current of 0.5 Amps. This value complies with the maximum allowed current according to the USB specification. If a large number of LED is integrated, the brightness is automatically reduced accordingly." I think this is the problem. 90 LEDs with 0.5A total current is only 5.5ma per LED. In 2-amp mode, each LED can draw 22ma of current. Using this number as an acceptable amount of current per LED, in 0.5A mode, the RGBpx port should be able to drive 22.5 LEDs at 22ma each. In your case, it is having trouble driving 9 LEDs (white).

I have a Farbwerk Nano sitting in a drawer that I bought on a whim for a future build. Since it seems to have the same limitations as the RGBpx port on the HFN, I can connect it, attached some LEDs, and see what happens. I will try to do this sometime this weekend and report back. Either your HFN has a problem or you are running up against the 0.5A current limitation. The math says that in .05A mode the RGBpx port should be able to provide 22ma of current to ~22 LEDs. You did not mention what brand of GPU block these 9 LEDs are part of. Maybe they require more current than the RGBpx LEDs and the HFN RGBpx port just can't provide enough current to drive them at the same brightness that the Octo RGBpx port can. I don't know how much DRGB LED current requirements vary from different manufacturers. A quick Google search says worst case is 50ma per LED, so even 22ma seems suspiciously low.

THIS PAGE on the EK site has a table of all (?) the EK blocks, what kind of LEDs they have, and power consumption including total amps and watts. They have several different types of LEDs. It does not say if these numbers are for worst case white at 100% brightness, but it's at least a starting point. Since you ordered a Farbwerk360, this is now academic.

Also, note that the Farbwerk360 and Farbwerk Nano support Transparency. When you stack different RGB effects (they call them LED controllers), the highest one in the stack blocks the effects under it. With the Farbwerk360, you can set a Transparency level which allows effects further down the stack to bleed through the effect above them. This is a powerful feature that allows some interesting things to be done. I am not sure if any other device with an RGBpx port supports Transparency (other than the Farbwerk Nano). I know the Octo does not and I suspect that the Quadro and other devices that have an RGBpx port also do not. If you are just setting solid colors or using basic presets, y ou may never use this feature. If you start customizing presets and stacking them, you probably will.
