Bad news team - I've been in contact with BlocC who said that smart fan speed is integral to it's operation and I doubt we'll have control over it :/
I hope that you are wrong and that true under volt + down clock is available.
It was available on the avalon 4.
But if you are correct then these will never work as well as I hoped for. I am glad to have the 2. And I will now consider more options. I may get a hosted s-7.
I'm hoping the same his time is odd at releasing info. Getting info at Saturday night is just normally not the time they would be sending out support info.
Who are you talking to at BlockC bonez? Can you post email or picture of email? The fact you spelled BlockC wrong and time you posted just does not give me ton of confidence in your info.
Lol it's Sunday I'm a bit hungover

I'm talking to Yan in the sales dep Sales Account <

After asking if there is a firmware update in the works where we will have full control over the fanspeed he said "The smart speed is very important. The reason the fan control works the way it does is because the chip needs to run at 75C for optimal efficiency. When it gets too cold you get a high error rate. If you want to verify just set your fan to min 80% and your hash rate will drop to about 3.0T"
I also asked him about the ambient temp being so high and he said "Most graphics cards run at 90 to 100 c. 75 c is the core temp of the chip. Ambient temperature and core are very different."
