Hey James,
I have to agree with bgrater7,
for example, I have a CPU cooler from alphacool, which only deliver a ARGB connection.
So I have two opportunities.
1. let the CPU cooler dark
2. connect it to the ARGB Header of my ASUS Motherboard and live with the fact, that it will never be synchronized with the rest of my stuff.
I'm super happy, how far the ICUE software goes.
But I'm very disappointed, that i can sync all my stuff, expect of the CPU cooler.
So my wish would be the same as bgrater's.
As i don't need to have every single LED controlled, it would be enough just to use the ARBG as one lightning area. Just as the "normal" RGB Headers.
