The heat does not increase it decreases slowly.
Lets say temp inside was 70c all power cut. Temps go lower slowly nothing wrong with that.
Temps dont rise there is no energy being sent to gear.
If unit can run 24/7/365 at 70c it can take three hours to cool from 70c to whatever,
Your fear is not logical or rational.
And the suggestion given that you can turn off internet whic will stop hash but let fans run is simply not needed to do.
As cooling the gear down from 70c to say 20c in ten minutes is harder on the gear then taking three hours.
Hi.
Yes you're completely right about that the heat does not increase as there is no more energy added. However the heat already generated will transfer to places in the miner where it's cooler when hashing because of the airflow.
I've never opened a miner (other than removing the fans to blow dust out and moving the jumper on the control board) so I don't know what other component are in there except for the chip boards, if any. The control board is also outside the miner so that is obviously not affected.
Anyway I'm sure you're all correct and next time I'll just unplug the power without thinking any more of it.
Thanks for your opinions.
BR.
