DSM-G600, DNS-3xx and NSA-220 Hack Forum

It seemed to me that this was a bug in the beta firmware. I think if you go into the webmin page for fan control and set it to some other setting and 'save' it, then set it back to the desired setting of automatic fan speed regulation or whatever it was, then 'save' again and I think the fans will then slow down and work as they should after that point, but until you do this, they will just run at full speed all the time. I'm going based off memory here as I gave my DNS-323 to my mother 2 states away, and just ordered another one for me, but it has not arrived yet so I cannot install that firmware version and test this phenomenon at this moment. But try that, what I described, and I think that fixes that problem.
