Electronics cooling

Raspberry Pi 5 cooling.

Compare component temperatures and airflow with and without the Active Cooler, using real simulations from the Vanellus API.

  • 8.6 W board power
  • 20°C ambient air
  • CHT + RANS heat transfer and flow
01 / Natural convection

Bare board

20°C288°C
Buoyancy alone cannot cool this fixed-load model. The run reaches its iteration limit with the SoC still far above its operating range.
02 / Forced convection

With the Active Cooler

20°C77.1°C
Adding the heatsink, thermal pads, and blower stabilises the simulated SoC junction at 70.6°C.

Colours show temperature, with a separate scale for each view. This is an illustrative fixed-power model; a real board would throttle before reaching the bare-board temperatures.

Run it yourself

Start with the complete case.

The guide’s Python package includes both configurations, STEP geometry, materials, and a short setup README. Add your API key to run the cases or adapt the design.
