PC fan simulator for airflow-aware builds
Plan case fan placement before the parts arrive. In supported cases, BuildCores lets you choose fan slots, flip intake or exhaust direction, and show airflow arrows in the 3D builder.

Why builders use it
BuildCores keeps the planning tools close to the parts list, so you can check the build, change a part, and keep going without rebuilding the plan somewhere else.
Fan slot planning
Place case fans in supported chassis and see the cooling layout next to the motherboard, radiator, GPU, and case panels.
Airflow direction
Check which fans are intake or exhaust without translating a diagram back to your case.
Thermal layout context
Review fan choices near radiators, GPUs, and restricted case areas before you buy.
Where it fits in BuildCores
Use these tools while you are choosing parts, checking the 3D view, comparing prices, or planning the desk around the PC.
Why airflow planning matters
Balanced intake and exhaust can keep a PC quieter and cleaner. The airflow view helps catch backwards fans while parts are still easy to change.
What you can tune
Open the case controls in the 3D builder to review fan slots and turn on the airflow overlay when the case supports it.
Check airflow with the full build
Use the fan simulator alongside compatibility checks, 3D placement, and price comparison instead of treating cooling as a separate sketch.
PC Fan Simulator FAQ
Is the BuildCores PC fan simulator a CFD tool?
No. It is a practical visual airflow and layout planner, not a full computational fluid dynamics simulation.
Can I preview intake and exhaust direction?
Yes. Supported builds can show fan airflow arrows so you can check direction while configuring the case.
Does airflow planning work with the rest of the PC builder?
Yes. It sits in the same 3D build flow as part selection, compatibility checks, RGB lighting, and pricing.
