Well that turned into something unexpected , but it all helps.
If your Canadian winters can't cool the units then it's saved me bothering to even try and test these tomorrow, i'll drop them in the room and put them back to auto.
Not so surprising is moving the fans back to auto after doing the firmware upgrade temperatures are down and voltage it up.
As for the mining so they were bought for bitcoin, it was my looking into something i should have left alone until i at least understood the basics of what these do.
Learning in public can and is appearing to be painful..
I never said my units have a problem with cooling at all...I just mentioned that they are running in a very cold environment so you would understand why your inlet temp is 33C and mine is 10C and the resulting outlet temp differences....I am fortunate to have a cool location to house my miners naturally. You can run the miners and achieve similar results regardless of where you put them really at this voltage...any extreme cooling benefits would only result in lower fan speeds as the chips all adjust voltages
I will be posting a review of SP20 in the next week
As I said 2.6.7 is old test version so anything is possible. Keep in mind that even though you set the upper voltage limit to .75v (default) none of your chips are using even close to that in the screenshot you posted...that's why I suggested upper limit of .72v, that and also the extra 100 or so GH/s u get above that is around 1W/GH which is not worth it
Learning is something we all do every day but it helps to pay attention....would you buy a hot rod and floor it out of the dealership parking lot without putting it through all the gears and not expect to hit a wall or 2?
