Hey there, I recently built a new machine (been in the PC space for about 8 years, but never built my own machine) and in that order I bought a single LL140 because, primarly, it was on sale, but also because of its RGB. I didn't do any research, and assumed I'd be able to use an RGB header on my MB. I was wrong. Fair enough, but I was wondering if I need to buy both the Commander Pro and the controller for one fan, or if just the Commander Pro is sufficent for one fan? Cheers!
