What he came up with is a very nice model of a radial engine. Everything was cut ... It’s a Pentium 4 heat sink with a very bright Cree Xlamp LED attached to the base. A bunch of Peltier ...

To meet these challenges, Tyco Electronics utilized Computational Fluid Dynamics (CFD) analysis to optimize both cost and thermal performance of next generation radial folded fin (RFF) heat sinks.

He added heat sinks to the SoC, Ethernet/USB chip, and voltage regulator. From his parts bin he grabbed a small heat sink that was probably used on a graphics card.

Thanks to radial heat sinks and a broad, PWM-controlled speed range, the compact CPU cooler offers sufficient performance as well as low noise levels at a very low price. Features.

Raspberry Pi 5's active cooler, with heat sink and radial blower. There's also a new chip on the Pi 5, built by Pi, to take away I/O functions from the AP.
