Huh. Never owned an Asus board. I wonder what they are/what qualifies as an "optical fan"
Visible ones...just in case you also might run invisible fans. Otherwise, I'm thinking they are fans for 3D glasses to keep them from fogging on the insides, similar to paintball goggles or scuba goggles.

Invisible fans? Sounds like I'm out of a job lol, no more wires to hide.......
Nice pump Op, all sorted on the monitoring wire then?
and as your psu is modular, you know you just run adaptors from the molex to the fans? or,
if you are adding fans at the rate I am, buy several fan controllers, plug the 3pins into them and plug a molex into the fan controller
