My cooling is basically a big box fan. If the box fan were to malfunction or trip, my room would overheat quickly and my miners will overheat too. I know the miners have overheat protection but is that good enough?
Does the antminer switches itself off completely when that happens or goes into some standby mode where it is still turned on?
I would hope it turns itself off completely as I might not realize it for hours...
So, do u guys install an electrical device (a contactor or something) to switch off the power if the box fan were to fail?
A fail-safe as u could say.
A surge protection device is necessary in case of lightning strikes.
Is there anything else to install?
The miner will automatically stop mining, and hopefully, your fan would be reliable to where this wouldn't be an issue.
There would be no point in putting a fail-safe.
You should definitely install a surge protector.
