Your questions answered
Will older versions of Raspberry Pi OS work with Raspberry Pi 5?
You will need the latest version of Raspberry Pi OS, Bookworm, for your Raspberry Pi 5.

Will my Raspberry Pi 4 power supply work with Raspberry Pi 5?
Raspberry Pi 5 is a higher-performance computer than Raspberry Pi 4, and you may have problems using an under-powered supply. We recommend a high-quality 5V 5A USB-C power supply, such as the new Raspberry Pi 27W USB-C Power Supply.

Will my Raspberry Pi 5 fit my Raspberry Pi 4 case?
Raspberry Pi 5 wont fit the Raspberry Pi 4 Case. We recommend the Raspberry Pi Case for Raspberry Pi 5, designed to help you get the most out of our newest computer.

Does Raspberry Pi 5 need active cooling?
Raspberry Pi 5 is faster and more powerful than prior-generation Raspberry Pis, and like most general-purpose computers, it will perform best with active cooling. The Raspberry Pi Case for Raspberry Pi 5, with its integrated fan, is one way to provide this.
