Field notes
Cooling load in Bangkok breakeven math
Heat is part of the electricity budget—especially in Thai classrooms where operators compare summer bills.
Hashrate tables that ignore cooling look optimistic on paper and fragile on the meter. In Bangkok, ambient heat means fans and air conditioning often run whenever miners do. Our profitability workshops treat cooling as a sibling cost to miner draw, not an afterthought.
Allocate, do not average blindly
If one AC unit cools miners and a workspace, estimate the share attributable to the rack. Seminar tables usually pick a percentage, stress-test it up and down, and watch how payback shifts. That range is more honest than a single heroic figure.
Immersion and air paths still cost power
Pumps, dry coolers, and exhaust fans belong on the same worksheet as the miners. Operators sometimes exclude them because they feel “facility-wide.” Breakeven planning only works when every watt required to keep the hardware online sits in the model.
Tie cooling to tariff cases
Cooling often peaks with afternoon heat—the same window where some tariffs climb. Pairing cooling load with time-of-use brackets is a standard exercise in our Electricity Budgeting Clinic and carries into the full-day breakeven seminar.
