Cooling Mistakes We See in Gyeonggi Warehouse Conversions
Repeated airflow and rack-layout errors that push mining rigs into lower efficiency classes than their bench ratings suggest.
Most mining facilities we visit in Gyeonggi Province started as something else — logistics storage, light manufacturing, or agricultural buildings retrofitted with industrial power. The conversion is fast; the cooling design often is not.
Mistake 1: Hot-Aisle Recirculation
Rigs exhausting into the same volume they draw intake from is the most frequent issue. We measure intake temperatures 8–14°C above ambient in these setups. Units that bench-tested as Class B operate at Class D within weeks.
Fix: Separate intake and exhaust paths. Even a simple partition wall with intake on one side and exhaust ducted outside makes a measurable difference.
Mistake 2: Rack Density Without CFM Planning
Operators fill every shelf because the electrical panel supports it. Fans ramp to maximum, power draw increases, and hash rate stays flat or drops as thermal throttling kicks in.
Fix: Calculate cubic feet per minute per kilowatt before adding racks. Leave empty shelf space for airflow if your ventilation system cannot scale.
Mistake 3: Ignoring Humidity
Korean summers bring sustained humidity above 75%. Condensation on cold intake surfaces and corrosion on connector pins are common in facilities without dehumidification. We have seen hash boards fail within six months in high-humidity environments that bench-tested fine in dry conditions.
Fix: Monitor relative humidity at rack intake. Target 45–60% for sustained operation.
Mistake 4: Mixing Efficiency Classes in One Rack
Placing Class A and Class D units on adjacent shelves creates uneven thermal load. The hotter units heat the intake air for their neighbours, dragging the whole rack down.
Fix: Group units by measured efficiency class. Position higher-draw units with direct exhaust paths.
What a Fleet Session Reveals
Our on-site benchmarks include thermal imaging that pinpoints these issues. The fleet summary ranks units by actual performance, not rated specification, so you know whether the problem is hardware, firmware, or facility design.
If your power bill climbed without a hash-rate explanation, the cause is often environmental rather than degraded silicon.
