Was not software related with me. Best thing you can do is place each fan into slot one of your RGB hub, if it works you plug the next and so on. If the fan lights up and the next one doesn't, the fan in slot 1 could still be at fault because the pass through is jacked up. It will take lots of trial and error. to be honest it's a **** system.
Also the RMA process sucks. They will require you to send your fans in first or pay $$ for an up front for an advanced RMA. Which is fine, but it took almost 3 weeks and countless emails to get them to refund me my money.
Good luck.
