Hi, I have the same RocketStor 6418s enclosure with RocketRaid 2722 Controller and, aside from the initial power-on brief spin, the two big fans never seem to come on. There is a smaller fan at the bottom that intermittently revvs up and stops and occasionally runs continuously for a brief time. The S.M.A.R.T temperature readings for the disks gradually climb through the 50-60°C over several hours of the enclosure being on and idle. According to a colleague the enclosure warning beep was sounding the day after I turned it on. According to HDSentienel one of the disks max temp during its lifetime was as high as 61°C, with the other disks not far behind that.
Has anyone found a fix to this that doesn't involve pulling the enclosure apart? I don't know anything about making after-market mods to fans/disk enclosures; ideally there'd just be some switch in the WebGUI or a firmware patch to fix the fan behaviour since they're definitely capable of running, they just never seem to turn on.
