It is an efficient, silent and easy-to-install cooling solution for users seeking stability and flexibility.
<span class="tb_red">Update:</span>
To make installation easier, '''the width of the C519 was changed from 45mm to 41mm in August 2025''', while other specifications remained unchanged. Currently, there are two versions of the C519 available: the '''C519 V1.0''', which is a '''45mm''' wide cooler, and the '''C519 V1.1''', which is a '''41mm''' wide cooler.

Q1: Question 1Does the C519 heatsink fit all CM5 IO boards, including third-party ones like the Waveshare CM5 POE IO Board/CM5-IO-BASE-A?
</div>
<div class="mw-collapsible-content">
A: The C519 heatsink fits the [https://www.raspberrypi.com/products/compute-module-5-io-board/ official Raspberry Pi CM5 IO board ] without issues. However, compatibility with third-party IO boards may vary. For example, on the Waveshare CM5 POE IO Board, the heatsink may interfere with the POE circuit's square inductor. In such cases, slight modification (e.g., trimming a small notch with a Dremel) might be needed to achieve proper fitment. Also not support Waveshare CM5-IO-BASE-A. Please check the layout of your IO board and C519 size before installation.
