If it's 5v ARGB, you can use jumper cables to connect the two D, 5V and G points together and then stereo everything via iCue by specifying the fans as RGB strips.

Attention: on the picture (white background) in the discussion the 5v and the GND are reversed. -> 5V is at the point where there is a gap in the connector ->
Example (The comma is the gap):
GND signal , 5V
Variant 2:
There is someone on Ebay who makes such cables himself:

This is if you want something ready-made (but more expensive)
Option 3 (software):
If you have an ASUS mainboard, you could connect the EK fans to the mainboard normally and then sync the whole thing with software:
