The Raspberry Pi Foundation has released a new product today. It’s a tiny $5 fan combined with a small heatsink for the Raspberry Pi 4. It works with the official case, below the top cover. That accessory should prevent the Raspberry Pi from overheating.

If you’re not familiar with the Raspberry Pi, it’s a cheap, single-board computer with a lot of connectors that is the size of a deck of cards. You can give it to a kid so they can play around with a terminal, you can use it for your weekend projects as the computing brain and more.
