The lower the static pressure the better the ventilation. Better ventilation leads to efficient mining. Efficient mining is necessary to make profit that can return what you had invested.
Methinks folks are talking about 2 very different matters namely, pressure through a miner OR room/building ventilation.A miner needs high static pressure fans to move the air through them.
Ventilation through a room is entirely different.
OP - which are you confused about?
The thing I am worried about is burning the miners due to overheating and all those issues. There are some videos on the web from some miners saying it doesn't matter how much air you are mining through the room but what matters is the static pressure. So that is why I am just trying to understand what it is, the concept from the miners point of view and how to accurately do it and take care of it so the miner life increases.
. Does this mean that the supply side i.e. the cold aisle side should have more air blowing and the exhaust should be less powerful than the supply side?
