A thermally conductive silicone pad transfers heat from the CM5 to the fins, with no noise and no moving parts. It improves the module\u2019s sustained performance and longevity, on the official IO Board as well as on a third-party carrier board.<\/p>\n<h2>Highlights<\/h2>\n<ul>\n<li><strong>Designed for the CM5<\/strong> : 41 x 56 x 12.7 mm, with a cutout above the onboard antenna and the U.FL connector.<\/li>\n<li><strong>Silent<\/strong> : passive cooling, no maintenance.<\/li>\n<li><strong>Conductive silicone pad<\/strong> already in place under the heatsink.<\/li>\n<li><strong>Easy mounting<\/strong> : held by the adhesive pad, optional M2.5 screws at the four corners.<\/li>\n<li><strong>Compatible with IO Case version 2<\/strong> and its fan.<\/li>\n<\/ul>\n<h2>Technical specifications<\/h2>\n<div class=\"mr-scroll\">\n<table>\n<thead>\n<tr>\n<th>Features<\/th>\n<th>Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Dimensions<\/td>\n<td>approx. 41 x 56 x 12.7 mm<\/td>\n<\/tr>\n<tr>\n<td>Material<\/td>\n<td>aluminum<\/td>\n<\/tr>\n<tr>\n<td>Thermal interface<\/td>\n<td>pre-applied conductive silicone pad<\/td>\n<\/tr>\n<tr>\n<td>Mounting<\/td>\n<td>pad adhesion, 4 M2.5 screws and 4 nylon washers<\/td>\n<\/tr>\n<tr>\n<td>Compatibility<\/td>\n<td>Raspberry Pi Compute Module 5<\/td>\n<\/tr>\n<tr>\n<td>Production<\/td>\n<td>until at least January 2036<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h2>Which one should you choose?<\/h2>\n<div class=\"mr-scroll\">\n<table>\n<thead>\n<tr>\n<th>Solution<\/th>\n<th>For which board?<\/th>\n<th>Type<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>CM5 heatsink (this product)<\/td>\n<td><a href=\"https:\/\/monraspberry.com\/en\/product\/raspberry-pi-compute-module-5\/\">Raspberry Pi Compute Module 5<\/a><\/td>\n<td>passive, aluminum<\/td>\n<\/tr>\n<tr>\n<td>Fan heatsink for Raspberry Pi 5<\/td>\n<td>Raspberry Pi 5<\/td>\n<td>active, heatsink and fan<\/td>\n<\/tr>\n<tr>\n<td>Ventilateur pour bo\u00eetier officiel Raspberry Pi 4<\/td>\n<td>Raspberry Pi 4 in its official case<\/td>\n<td>active, fan<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p><strong>Our advice:<\/strong> on a CM5, this heatsink is the first choice.

As on the board, the clock speed drops automatically when the temperature rises: a properly fitted heatsink pushes back this threshold and stabilizes performance during compiling, transcoding or long computations.<\/p>\n<h2>Box contents<\/h2>\n<ul>\n<li>1 aluminum heatsink with silicone pad<\/li>\n<li>4 M2.5 screws<\/li>\n<li>4 nylon washers<\/li>\n<\/ul>\n<h2>Recommended accessories<\/h2>\n<ul>\n<li><a href=\"https:\/\/monraspberry.com\/en\/product\/official-raspberry-pi-cm4-dantenna-kit\/\">Official Raspberry Pi antenna kit<\/a> : connect it to the U.FL before fitting the heatsink.<\/li>\n<li><a href=\"https:\/\/monraspberry.com\/en\/product\/raspberry-pi-usb-c-27w-power-supply\/\">Raspberry Pi USB-C 27 W power supply<\/a> : for the CM5 IO Board under load.<\/li>\n<\/ul>\n<h2>Uses and projects<\/h2>\n<ul>\n<li><strong>Clusters and continuous computing<\/strong> : Edge AI cluster with the Compute Module 5.<\/li>\n<li><strong>Fanless products<\/strong> : kiosk, gateway or display where silence matters.<\/li>\n<li><strong>Cooling properly<\/strong> : the principles of <a href=\"https:\/\/monraspberry.com\/en\/refroidir-son-raspberry-pi-5-ventilateurs-dissipateurs-ou-boitiers-passifs\/\">cooling your Raspberry Pi 5<\/a> apply to the CM5, which uses the same BCM2712 chip.<\/li>\n<\/ul>\n<h2>Frequently asked questions<\/h2>\n<h3>What is the Compute Module 5 passive heatsink for?<\/h3>\n<p>It dissipates heat from the CM5 to preserve its performance under sustained load and its longevity, silently.<\/p>\n<h3>Is it compatible with the Compute Module 4?<\/h3>\n<p>No, it is designed for the Compute Module 5.<\/p>\n<h3>Does the heatsink need to be screwed down?<\/h3>\n<p>It is not mandatory: the silicone pad adheres and its hold improves over time. The supplied M2.5 screws provide mechanical fixing.<\/p>\n<h3>Does it fit in the official IO Case?<\/h3>\n<p>Yes. With version 2 of the case, it fits alongside the fan; with version 1, the fan must be removed.<\/p>\n<h3>Is it suitable for a Raspberry Pi 4?<\/h3>\n<p>No. For a Raspberry Pi 4 in its official case, use the fan designed for that case.<\/p>\n<h3>Is thermal paste needed?<\/h3>\n<p>No. The conductive silicone pad is already applied under the heatsink: simply remove its protective film before fitting.<\/p>\n<p>See all Compute Module products.
