So, Xilence sent me over their new Internal Fan Control Panel that fits into a 3.5" bay, it features the ability to control the speed of up to three fans, and has lighted accents around the dials which are also reactive to sound. You can of course turn the lighting off, or all the way on, or even adjust the sensitivity of the lighting reactions to sounds.
