I am setting up a mining operation with 1,000 Antminer s9 with 1,500W. Each has a 200 CFM fan. I figured out at 4.6 c /Kw power costs,the total power costs per month is $52K per month. I am trying to figure out or estimate the cooling costs. How do I do that?

I have read that in a data center in general 30-40% of total power consumption is in cooling. Can I extrapolate and use that to estimate the cooling costs for the cofiguration.

I was advised that use of 40 Variable Speed Fans costing about $895 each and  Chiller costing $27,000 would suffice? How do I estimate the energy consumption for such configuration to come up with a monthly estimate of costs.
