@tom.ronat Monitoring of the control box fan has been added in PolyScope 5.10. See [release notes](https://forum.universal-robots.com/t/release-of-urcap-sdk-1-12-0-polyscope-5-10-and-3-15/13012).

Try looking inside the control box when you start the robot to verify that the fan is spinning. If it isn’t you might have a cooling issue.
