Questions about CM H500M and Gigabyte Z390 Aorus Ultra RGB hookup
Hello all, I'm having some trouble figuring out the A-RGB setup combination of my case and motherboard. I'm using a Gigabyte Z390 Aorus Ultra motherboard in a Cooler Master H500M. The case has ARGB connections for both Asus/Asrock and Gigabyte separate. The Gigabyte cable is 3 pins while the Asus is 4 (with one blocked off). My understanding is that Gigabyte switched to the 4 pin on their newer motherboards. If this is correct, does this mean I should use the Asus connection from the case to the motherboard?
I can't seem to work out where exactly on the motherboard I should be plugging the case into. I assume the connections go into C1_LED and C2_LED but the pins don't match the Cooler Master Gigabyte connection from the case. Here are two photos, one of the cables from the CM, the other a close up of the C2_LED on the motherboard.
