Both of these are set to 5v as per the case manual. This jumper is connected to D_LED1 (page 5 of manual link) and i have also tried on D_LED2. On the case, there is a cable that needs to be connected to Digital RGB header on the mother board (step 4 - of manual link here) My assumption is the case is 'asus aura sync' and 'msi mystic light sync' compatible, but not 'Gigabyte RGB Fusion' compatible. I can only presume that the Gigabyte RGB controller thing, isnt compatible with the Phanteks LED strips. I do not have the 'front' leds (nor one on the power button and/or hdd activity, but not sure if it has one in this case) working. I have everything connected correctly (to some degree) as i have the side of the case where it has a LED light in it, working correctly but displaying the wrong colors (eg when i select red, it displays free, green is blue, and blue is red). Well, i have jumped back into getting my own build (specifically for VR but that's beside the point) and have purchased a Phanteks P350X Tempered Glass D-RGB Black Case ( link) and a Gigabyte Aorus B450 Pro Motherboard ( link). I just logged in and saw i have a '15 year award' wow!
