OK on my other older rig I have i7 7700, gtx 1060 6, 16gb corsair vengeance rgb and asus prime h270 plus (has no 3 pin). I also have some corsair ll series 120 rgb fans. I have two on my hyper 212 led cpu cooler, one as my rear exhaust, one 140 as my top rear exhaust and finally two as intakes in the front plus my rgb ram. now i have them hooked up to the hub that came with my fans and the hub is going to sata power and into my mobo 4 pin connector. Now i like that when i play certain games like far cry new dawn my corsair fans plus the ram and my razer keyboard, mouse and pad light up according to the game. for example if i die everything turns red, if i look at the sky everything turns light blue and so on. I like that.My new system:rog strix b450 fgaming2600x32 corsair vengeance rgbdeepcool captain 240 pro aiomatrexx rgb casertx 2060 rgbNow this mobo does not have a 3 pin either. so i hooked up my 4 rgb fans (came with case) and my aio to the hub the case came with. Then into the sata for power. hooked up my aio to the hub and the mobo cpu fan etc. This pc does not do the color changes my other rig does during games. ?is it because i have no conncection going to the mobo 4 pin connectors?would like some advice. right now all fans, aio, rtx and my ram all stay in rgb colors which is bad ass. But i would like for it to do the color change during games. thx
