How much does it cost to run these large exhaust fans? What's their typical draw?
I'm a hobby miner with a hot room, so I'm curious what added cost these things have, compared to running a box fan or playing with higher AC use in my house.
I'm running one of
these in my garage. It's loud, and pulls ~ 500W by itself, according to the label on it, but it moves the air through the exhaust hose very quickly. I also have one of
these pushing air over the equipment, with everything enclosed. This allows the ~30 cu ft of air that the miners occupy to be completely refreshed every few seconds. It's way cheaper to move a lot of air than it is to cool the air, so AC is a total waste of money and energy for this kind of thing.
I'm intrigued by that blower/hose combo. How well does it work if you have a wider area of hot air from multiple rigs? Does the hose constrict the air movement? I like the idea of something that can be moved around if it needs to, but is more powerful and longer lasting then a box fan.
