Been away from the screen, as I was on this forum so late last night. Those who were around at that point know this. I've just been getting to grips and learning more about what components do what and when upon the board.
Been trying to catch up here, but am still confused as to the purpose of the opening of the casing and top loading of fans. It makes zero difference, it just appears to be a bizarre form of planking.

The temps ascertained by the BertMod (great work that man), reveal the voltage regulator temps, and not the ASIC. The voltage regulators can handle in excess of 100 degrees Celsius - ambient (surrounding environment) - so blowing a fan on them is pointless.
you are talking out of your ass... get some more sleep. There is endless proof to the contrary that lowering temp = better performance for long stable hashing. You might be talking about 10 minutes which would be a long time compared to what my miner was tested before shipping
