3D PC Airflow Simulator

Place fans in five case styles, from a small Mini-ITX case to a full tower, or start from 26 ready-made layouts. Change fan speed, direction, and model, add an AIO radiator, and move parts around.

Each run shows your case pressure and how much air reaches your graphics card and CPU cooler. You can compare layouts, then share one with a link or a picture.

The free simulator preview plays recorded runs of four layouts, so you can see it in action first.
