Home AI airflow planning
Start with heat.
Budget the air.
Enter one to eight GPUs, total steady power, and measured outlet-to-inlet air rise. Get an ideal bulk-airflow floor. Nothing is uploaded.
Planning math. Not installed airflow, a fan recommendation, GPU temperature, or a safety limit.
Power in. Warm air out.
Find the ideal floor.
Use watched steady board power or an exact documented total. Air rise means outlet air minus inlet air near the row. It is not GPU temperature.
Standard-day air properties. Real restrictions and leakage are not included.
What the number cannot answer
A floor is not a finished system.
No GPU temperature
The card, seal, case, and recirculation still matter.
No safety limit
Verify power and watch the first load.
Fixed method
Watch the first loadPhysics shown. Limits shown.
The budget uses standard-day air density and specific heat from NASA with the sensible-heat airflow relationship published by the U.S. Department of Energy. Read the fixed rules.
