The Raspberry Pi 4 Case Fan + Heatsink is compatible with the Raspberry Pi 4 and the Raspberry Pi 4 Case. Designed for anyone who wants to push the performance of their Pi, as well as overclockers and other power users, it keeps your Raspberry Pi 4 at a comfortable operating temperature even when under heavy load thanks to both a mini heatsink that goes on top of your CPU and a fan that clips into the official Raspberry Pi 4 case.

Please note: You do not need a fan for your Pi as it will automatically adjust its speed to avoid overheating. The fan is designed for use cases where you need to run it at top speed for a long time, say during some Machine Learning, rendering, emulation, or video playback.

Features:

• Fits perfectly into Raspberry Pi 4 Case lid - Note that this item doesn't come with a Case, you need to purchase that separately!
• Temperature-controlled fan delivers up to 1.4CFM of airflow over the processor memory, and power management IC
• 18mm x 18mm x 10mm heatsink with self-adhesive pad improves heat transfer from the processor

Additional note: This product is only the fan. Raspberry Pi 4 case is not included.
