Canon EOS R5 heatsink modification service from the NJ-based company Kolari Vision promises to significantly improve the recording times in 8K. The modification includes the replacement of Canon’s internal aluminum heatsink with a larger copper heatsink and thermal pad that dissipates the heat into the camera chassis. The cost of the service is $400. Announced in summer of 2020, both Canon EOS R5 and R6 cameras were troubled by overheating problems when recording video in certain modes. While Canon later improved the recording times of the EOS R5 with a firmware update, unlimited recording times in 8K, or 4K HQ are still not possible. Make sure to check our Canon EOS R5 Review and our EOS R5 Lab Test to learn more about the camera. Replacing the Canon EOS R5’s Internal Heatsink In November 2020, Matt from the DIY Perks Youtube channel published a long and useful video about modding the Canon EOS R5 and getting unlimited 8K raw recording. After some temperature measurements and experimenting with water cooling, he was able to get an unlimited 8K recording. He then created a more practical solution by designing a better and larger internal heatsink out of copper rather than Canon’s original aluminum one. Matt’s heatsink also directly touched the camera chassis at the back via a thermal pad to further spread the heat created by the sensor and image processor. My assumption is that Canon was unable to do that as with the modified heat sink as the camera body...
