This is interesting. Supposedly if you remove the cards from the camera you can record in 4K HQ externally to an Atomos Ninja V with the R5 for up to 4 hours continuously:

Previous tests of external recording in the downsampled 4K HQ mode only achieved 45 to 75 minutes before overheating. Removing the cards from the camera does turn off the heat-related recording countdown timer (since that is aimed at internal recording), and so it's possible that this somehow affects the camera's shutdown logic, although the reasons for this are unclear. 4K 60 output to an external recorder evidently does not cause overheating independent of whether there are cards in the camera.
Not sure if anyone else has reproduced these results yet, but another interesting data point in the overheating saga.
