The Argon40 Fan HAT for the Raspberry Pi Model B boards is a great way to cool your board during more intensive applications. This software controlled fan comes in a typical HAT configuration and plugs right into the 40-pin I/O header on the Raspberry Pi. It will work with the 4, 3B, and 3B+ and fits in all the Argon40 cases we sell (It comes built into the Argon ONE, so no need to buy it if that's the case you're using.

For quieter cooling, check out our line of heatsink cases or the Argon NEO.
