Also I have further information that up to 90 degrees is safe so if you are struggling to keep it under 85 with the overclocking and cgminer's throttling is kicking in regularly, you can kick the overheat temp up to 90. I will be changing the default to that in the next version. The device internally sheds cores transiently anyway if it thinks it's overheating, and trips a thermal overload flag should all fail which makes cgminer shut it down so there are countless ways the device is protected.
The device will increase/decrease its speed if it is cold/hot enough...... Havent seen one unit at 500ghash without manual overclocking
We will refund you if we getting cheaper shipping..... havent seen anyone get refunded yet
Personally I'm starting to think they may be worse then BFL, at least BFL will post updates, they waited 25days to post an update......
They even just outright lied.
