Crisp on the outside, thoughtful on the inside. A keeper.
Summary
A practical guide examining whether a Raspberry Pi needs active cooling. The article explains that fans are not always necessary — they're mainly useful for Raspberry Pi 5 models, heavy workloads, enclosed cases, or when heat causes throttling. For light projects, older models, or short sessions, passive cooling or no extra cooling is often sufficient. The author shares personal experience about how a fan was included in their first kit but turned out to be unnecessary for many use cases.
