On my L3+ I'm running at 444 (580Mh\s) and the fan is set at 60%. My Antminers are in a server room and temps range from 47 to 53 degrees celsius. I didnt overclock my D3 miners as they are running at 17500Mh\s with default settings but I did set the fan at 70%.
To confirm you can overclock the S9. As an FYI any Antminer device that is overclocked instantly voids the warranty
Just a heads up... If you don't keep that cool... You'll brick that L3+
Don't push much past the 400-410 Freq range...
I may or may not have done that by accident with an L3+ ... Don't ask - it was stupid.
