david105396 as you will get your miner soon I am very interested in some information.

The relationship between temperature and overclocking.
The relationship between vcore (not me lol) and overclocking.
The relationship between temperature and power consumption.

If there is enough overhead in the stock heatsink you could test it by controlling the fan manually and setting it to the maximum. If there isn't it will also be interesting.

My guesses are that overclocking will be heavily dependent on temperature a midly on voltage hitting thermal limits with slight increases on vcc while on stock cooling, I also think that it is quite likelly that there is a significant decrease in power consumtion with decreased temperatures. For those things to be really noticeable we need at least 20ºC of difference.

That information would really help us extracting the best overclocking and or getting a better hash/w. I am building a custom cooling and it would help me quite a bit.
Also, what is the maximum overclocking and voltage that the interface/hardware lets you set? (even if it will never reach it with aircooling it might with water or phase change and what could be reached could determine what kind of cooling is worth).
