I've been playing with the setting trying to find a low wattage but high hashrate setup and so far the best I've gotten is out of 490 Frequency, 1150 Core Voltage and Fan Speed 80%, it hasn't went over 16.5W and it's staying between 975GH and 1.3TH. The fan being at a constant 80% seems to keep the temp between 50° and 67°ish I haven't seen it go higher as of yet. Hoping I finally can set it and forget it. Lol.
