Open-air rig airflow that survives a humid Korean summer

Closed cabinets look tidy in photos and punish shelves when outdoor humidity climbs. Warm, moist air lingers between cards; fans recirculate the same pocket; hashrate softens while temperatures creep.

Give the shelf a direction

Decide where cool air enters and where exhaust leaves the room. In lab exercises we tape a temporary intake path so learners can feel the difference with a simple anemometer and a thermal gun. The point is not the tape — it is noticing that undirected air is not a plan.

Spacing beats louder fans

Cranking RPM to compensate for stacked cards often adds noise without fixing recirculation. We prefer measuring delta-T across the shelf first, then adjusting vertical gaps and shared intake fans. Many apartment builds improve more from two centimeters of extra spacing than from a second RGB blower.

Seasonal checks

Revisit intake photos and temperature logs when monsoon weeks arrive. A layout that worked in March can choke in August. Our Cooling Basics Lab walks through a short seasonal checklist you can repeat without returning to the studio.
