“The Raspberry Pi 5's official active cooler is a lifesaver for heavy workloads. It pairs a large heatsink with a variable-speed fan, keeping your Pi cool and quiet until needed. The downside? It won't work with the official case.”
“I have yet to thermal throttle using this little cooler, and it is very quiet except on startup where it ramps up for a few seconds. Not much else to say, but I would highly recommend this if your projects require higher cpu usage.”
