Build your PC in a 3D case, add fans, and run real airflow physics through it. See where the air goes, your case pressure, and how hot your graphics card and CPU get. Then change a fan and compare. Includes real cases from Corsair, NZXT, Lian Li and more.
Hi Product Hunt! I built PC Airflow Simulator because picking a fan layout usually means guessing, buying fans, and hoping your temperatures drop.
You set up your case in 3D, place each fan, and pick your graphics card and CPU. Then you run the air through it and watch where it goes. You get your case pressure, the air reaching your graphics card and CPU cooler, and how hot each chip runs.
The most useful part is comparing. Save a build, add or flip a fan, then run it again and see both side by side. In the gallery, adding four fans to a stock Corsair 4000D Airflow takes the graphics card from 80 °C to 74 °C.
It has real case models like the Corsair 4000D Airflow, NZXT H5 Flow, Lian Li O11 Dynamic EVO and Fractal North. Everything runs in your browser, and it's much faster in browsers with WebGPU.
The full simulator comes with Computer Info Bits Pro, at US$10 a month or US$60 a year. One case type is free as a preview, so you can see how it works first.
I'd love your feedback. Which case should I add next?
