PC cooling and airflow calculator
Enter component TDP and fan layout to check airflow, case temperature and approximate noise.
Result
- Case type
- Mid tower
- Intake airflow
- 83 CFM
- Exhaust airflow
- 41 CFM
- Airflow margin
- -64 CFM
- Target temperature rise
- 10 °C
- Recommendation
- Use stronger fans or reduce heat load.
- Formula
- required CFM = heat W x 1.76 / target ΔT °C

PC case airflow, cooling and fan layout calculator
The calculator estimates heat load, required airflow, effective airflow after case restrictions, case air temperature and approximate fan noise.
Use the comparison table to test simple intake/exhaust layouts before choosing case fans or changing fan curves.
Estimate airflow before buying fans or tuning fan curves.
- Choose a scenario
- Adjust TDP and fans
- Compare airflow and noise
