I want to measure how effective air cooling is in controlling the amount of heat buildup inside the case. Usually, evaluations are made based on simple criteria like fan counts, RPMs, and placements, but are there other methods as well? For example, how do factors like humidity levels, airflow direction, or whether fans are blocking each other affect performance? I’d appreciate it if you could share your experiences on the topic.
How is air cooling performance measured?

I could even adjust the fan speeds manually. I synchronized CPU/GPU temperatures and fan speeds using programs like OCCT or HWMonitor, ensuring stable performance without exceeding 75°C even under max load. Humidity isn't a factor here, but airflow direction is crucial—I kept the sponge filters on the front intake clean and paid attention to cable management to let the fans do their job properly. Placing fans diagonally (top and front) also gives the best performance, as long as the rear bottom fan expels hot air without disrupting the middle airflow. If the fans block each other (e.g., the rear fan directly facing the front fan's exhaust), pressure builds up and cooling efficiency drops—I figured this out through trial and error, and even small tweaks in fan placement can make a big difference with a bit of patience.
