sorry, just reading this...so
@VRMan25 , you got a 3500x correct, but with standard rgb fans, not the link ones? the non link fans are RS120 argb fans, so that's what you want to keep hing looking the same..if you bought the case with link fans they're RX120's...the case doesn't come with reverse fans as far as I'm aware...Corsair are late o the party regarding reverse fans...with the nautilus 360 rs fans, you now have 6...I prob wouldn't bother getting more tbh, but if i did you can put one in the bottom front drawing air up..that'll be 4 in, 3 out, so positive pressure in the case, but seeing as the 3 exhaust through a rad anyway, you'll probably have positive pressure in here anyway...
if you want to fill it up get 2 more rs..one for bottom front, 1 for exhaust at the back by the i/o (might as well get the tripple pack then at £31.66 as 2 will set you back £24.98..keep one as spare backup in case 1 breaks)
If you want ICue to control the rgb on the fans, you'll need a hub...don't think Icue will work directly through the mobo...er, quick scan and looks like the rs fans rgb has to go through a controller, they wont work directly through the motherboards..oo, that's tough selling a rgb case with no controller..they really pushing you towards the link version then as that does have one
b grade commder core below..that can control 6 fans..so 100% wouldn't bother getting any more fans then.
No, iCUE cannot directly control RS fans without a Corsair RGB controller like the iCUE LINK System Hub or a Commander Core XT. iCUE requires a dedicated RGB controller to manage lighting and fan speed, and RS fans need a compatible controller to connect their RGB connector
