NZXT Technologies Sentry 3 5.4-Inch Touch Screen Fan Controller Cooling AC-SEN-3-B1
The Sentry 3 brings you the best of both worlds by combining 15 watts of power per channel with an extraordinarily intuitive UI, giving you complete control over your entire rig's cooling with the swipe of a finger. The newly introduced PowerSlide Bar gives you ultimate control over your fan channels, letting you adjust speed on the fly. Channel linking allows you to join any of the five fan channels together and control the link group simultaneously.
