Swagata

yes i tried pushing that and case push button as well. pressing multiple times, press and hold. just nothing. the shop i bought it from doesnnt provide warranty. so i guess i am screwed. but anyway to determine what is actually defective ?

tried three fan in port 1 seperately. none works. these means all the fans led or hub is defective right ?

yes, the fan hub is connectedto sp lighting controller which is also connected to case push button. yes fans r connected as 1 2 3. can i connect one fan's rgb cable to motherboard just to see if the rgb works ?

I recently bought an corsair 570x. The front 3 fans are running but rgb not working. Yes, I did plugged in the rgb hub sata power. I am thinking something is defective like the fans led or or the hub or rgb controller. How can I determine that ? Or Am I missing something ?
