Whether the lack of grounding could damage the power supply and the miner, and whether it would reduce their lifespan?

If I restart the PSU and let the miner cool down before a power outage and then shut the miner down, and I do this operation every two days, will it not reduce the lifespan or cause damage to the miner?

What is the reason why M65S can achieve high temperature output?

What is the decibel level of noise produced when the hydro-cooling miner or immersion cooling miner operates?

What is the maximum switching time (this is the switching time between different power sources (for example, the general network and the energy storage system)) between power supplies in milliseconds?
