My spacer above asks a good question. Well this setting is quiet not silent but quiet. Good for the dorm room good for an office space heater if the office is not quiet.
This setting pulls under 825 watts at the wall. means you can use this miner with small 120 volt psu's.
I know it does not seem like it but Fall will be here soon and many people use a miner to space heat.
so lets say you go for 1450-1500 for the lessor model. this should pay off with free power and 2% jumps in a year.
not quite what someone may want.
So rather then freq of 350 and fan of 23%
A setting of freq 375 and a fan of 25% or
a freq of 400 and a fan of 30% ------- starts to be loud
it may be what works for a free power miner needing quiet mining is a bit more testing.
setting below is freq 375 and fan of 30% and it is getting louder
freq 400 fan 33% and the sound would be too loud or loud enough to annoy
freq 404 fan 33% the hash rate and temps moved a bit higher and of course the sound is too high. my psu is a 1000 watt plat enermax single rail
freq 406 fan 33% the hash rate moved up temps are about the same. This 406 33% setting may be a good for my unit. my psu should hang in until I go to freq 500 ( a guess)
next is 408 setting same 33% we finally got more heat then I like 97 top temp.
this is a 412 setting and a boost in the fan to 34% even though I raised fan speed reads the same rpm but hash is up and temps are down. this may mean rpm gauge on fan is false on 33% setting or 34% setting. this kind of makes testing every freq worth it
here is freq 416 fan at 34% hash rate is almost 9000 but temps went close to 98
