I’ve only connected the CPU fan and the thing lights up like a strip club neon.
I haven’t paid 7600 PLN for a LASIK operation just to get another one years later with inflated prices just because hardware vendors hate their customers. How can I disable this eye sight destroyer?
Also the RGB connector is undocumented. The motherboard has a 5V and 12V pin header for that, but it’s stated nowhere in the CPU manual which voltage is appropriate for the header controlling the LEDs.
It’s all either 12V 4-pin RGB (12V, G, R, B) pure analog controls (i.e. your current source on each channel control the brightness, all diodes shine the same colors), or 5V 3-pin ARGB (5V, D, N/C, GND in a typical 4-pin-wide format with 3rd pin missing) like this:
ARGB sometimes has proprietary plugs, but can still be determined by the number of pins present.
EDIT: googled a bit and this might be of use:
Sect. 5. (Connect Fan and RGB/USB Cable to Motherboard) clearly says there are two methods of controlling the RGBs, either via USB cable or via RGB (the 12V one). For USB control I guess you want to use their control utility:
