oops, forgot to add..... One last question mate.
Crytptalk mentioned the Scrypta OC firmware I have the link for, mentioned above, doesn't require extra cooling for the a2 chips because the firmware apparently controls the temperature of the a2 chips to prevent overheating.
Question: Does your latest update to your firmware, do the same, so I won't have to build an airconditioner pipping assembly to feed the air con air straight to my miners intake fans?
The temperature is controlled by decreasing the amount of work going to the processors.
Just try it out, see what the hash rate (poolside) does and decide what to do.
