C700M LED malfunction in COSMOS Series Posted January 17, 2019 Good news! Called up the Cooler Master support line and got through to someone almost instantly. Here's what I know now: - They're dealing with a backlog of tickets from over the holidays (hence the support delays). - They're aware of the LED issue though I think it's still too early for them to know what the exact cause/solution might be. - They're sending me a replacement top panel, and if the problem comes up again they said they can send another (though ideally after they've fixed whatever is causing this to begin with, because at that point it's likely a manufacturing defect).
