The Raspberry Pi 4B has attracted a lot of attention since its announcement and release on June 24, 2019 – as well as discussion about heat dissipation, since the impressive 1.5GHz, quad-core processor and USB 3 controller tend to run hot. This is the first Raspberry Pi for which many users will have to deal with heat issues to maintain peak processor performance during ordinary computation.

This guide provides information about some aspects of heat management on the Raspberry Pi 4B. The issues that this guide will seek to explore include:

• How well do different cases for the Raspberry Pi 4B control heat?
• How much does the CPU heatsink improve heat dissipation?
• Does the July 2019 firmware upgrade reduce heat production?
