Question Anyone here own the Corsair ICUE 4000D RGB Airflow case?

[Dave3000]

I'm looking for a new case for my gaming system. I decided that I don't want the Corsair Frame 4000D RS because the IO ports of that case are on the bottom and I place my tower on the floor and I don't intend to place whichever new case I end up with on a desk. Now I'm considering the Corsair ICUE 4000D RGB Airflow case. Can the RGB of the case fans be turned off without installing the ICUE software as I prefer no RGB. I would get the non-RGB version, but Best Buys near me and the closest Micro Center to me does not have that one in stock and I prefer to buy a case locally than getting one shipped to me.
