If your Raspberry Pi 4 projects are making the mini PC run a little hotter than expected, you may be interested in a new video created by Christopher Barnatt over at Explaining Computers. Following on from creating his very own custom cooling solution for the Raspberry Pi 4 mini PC. Christopher has also put a couple of Raspberry Pi active cooling solutions to the test, unboxing and using the Pimoroni Fan SHIM, 52Pi ICE Tower Cooler, and Noctua 40mm fan in 3D printed mount.
The video embedded below includes Sysbench CPU stress tests, and comparison of results with passive cooling in Christopher’s earlier Raspberry Pi 4 Cooling video also available via his excellent “YouTube” channel.
Shortly after the launch of the Raspberry Pi 4 the official Raspberry Pi Foundation rolled out a new firmware update to bring the temperature of the mini PC down a little more, but actively cooling the mini PC is a great way to help get more from your processor.
