It's possible there may be only one temperature sensor per board too, so you may not be seeing the far-end temperature. Additionally, with the stock fans removed, the Antminer will not be able to ramp up the fan speeds should it detect that the temperature is too high. If the exhaust fan is relatively quiet, I think I'd be inclined to keep that one on, just in case.


Unless you have a 'converted' loft, shouldn't there be ventilation gaps/holes in the eaves?

My house is 118 years old and the cross ventilation is what comes in under the roof tiles.

Wouldn't be a clean stream of air through that that I can imagine to be able to duct it into a miner.
