I was wondering if there is a place where I can find the heat-sink x-clamp for Jetson Nano module.
You posted in the Virtual GPU forums. I am moving this to the Jetson Nano forum for better visibility.
Please refer to thermal design guide in DLC: https://developer.nvidia.com/embedded/dlc/jetson-nano-thermal-design-guide-1.3
Are there any commercially available solutions for those components?
You can check with the vendors in ecosystem. Jetson Ecosystem | NVIDIA Developer
