After a R5 body strip down and the removal of the memory battery, claims are made that the overheating warning goes away and the camera can do a second round of 8K for another 20 minutes ....... meanwhile there is no real sign of overheating ........
......... leading to conclusions about timer limitations rather than heat control  .........

Sony must be loving all this ...... their designers are probably whistling away merrily whilst designing more than adequate heat sinks for their new A7R.IV 8K ready  .........
