Neither is a problem in the sense that both noise and water consumption can be mitigated with some minor (relative to the total cost of a project) capital investments. If these were rational objections, states and municipalities could simply issue noise codes and water access caps, then let the companies figure out how to work within the lines. Instead, we’re left with blanket bans

No, it’s not the noise it’s the power consumption. Your locale becomes a power consumption hog so your off-peak hours and your peak hours become very similarly priced. Noise can be dampened, the power bill cannot.

This is actually a meme/fake videos on the internet, where they add random noise over their videos while recording a datacenter to make it seem really loud.

Realistically you can only hear it if you're within 30-50 feet of the data center, unless there's a separate diesel/natural gas generator.
