NZXT Sentry 2 LXE Fan Controller @ OC3D
Quote: "Enter the NZXT Sentry 2 LXE fan controller. It absolutely covers the noise element as it enables 'on the fly' adjustment of fan speeds allowing you to turn it all down when you're browsing the internet and push them all back up for your gaming session. Perhaps more importantly it also covers the gadget aspect. A far cry from the "dial" based controllers we're used to, this is entirely touch-screen and external too. But before I get ahead of myself."
