The first time around the CPU temperature went to about 80Celsius right before and during the freeze. I installed a temperature controlled fan and now the machine does not get hot even on a freeze. Screenshot of the metrics from the last freeze august 29th around 22:50-23:05 are attached. (Turned off and started the machine around 23:06)

The Validator missed all 6 attestations from 22:38-23:10. I dont understand how the logs can still play nice.
Beacon chain and validator logs on first sight suggest that the blockchain ran smoothly during the freeze, but “Could not connect to powchain endpoint: could not dial eth1 nodes: eth1 node has not finished syncing yet” ma ysuggest there was an error in the geth sync. Those geth logs sadly are not available on my system anymore.
some beacon-logs from that time:
