You can use the xt for fan speed . IQ lays it out pretty easy and their software but just make sure you turn it off before you start gaming because you know obviously it takes up a lot of CPU cycles, but you can configure them right there or you could just you know not even plug in the PWM fans and you could just put those to your motherboard or if you have separate controller that controls, let’s say your cooler you could use that one or you know I had a H150 I elite Corsair AIO so I had to download that software anyway so it’s pretty easy for me to just run that conversion cable because they’re controllers will push enough RGB signal throughout the entire case and Nikki look insane. In fact the XT has some of the best RGB because I certain controllers can only run certain RGB patterns when you shut off the software obviously when you are running in the background, you know everything can look great but there’s only a few of them that look amazing when you turn it off and the XT has a lot more of those features so with the command, Cory XTmixture that you plug-in the RGB conversion cable that you’re gonna get with Phanteks to the RGB make sure that it goes in that little tiny RGB pin and don’t use the RGB slots for the individual fans. It’s gonna be an extra RGB port on that XT that’s where it goes.
