Hi,
I have 6 Riing fans connected to 2 controllers linked with the controller cable. When they start they are all in sync however after 10 minutes or so 1 set will be further behind in the colour range until they are completely out of sync i.e. 1 set red the other blue. Eventually they will become the same colour again and the cycle will start over. At first it's not too bad as they are only a few shades different however it becomes very noticeable. Any ideas ?
