Sometimes, being a good neighbour is making others feel like they don’t have one at all. Or so it seems with the recent lawsuit being faced by Microsoft’s much-touted $7.3 billion AI data centre in the US. In early 2026, Microsoft CEO Satya Nadella proudly announced his company’s data centre in Fairwater, Mount Pleasant, Wisconsin as the “world’s most powerful AI data centre.” He claimed it connected “hundreds of thousands” of power-hungry chips “into a single seamless cluster.”While tech giants and AI enthusiasts may have been excited for another stepping stone being laid for the anticipated AI boom, the local residents are less than elated about the facility cropping up in their neighbourhood. As per reports by The Milwaukee Journal Sentinel, three residents of the village of Sturtevant, which is adjacent to Mount Pleasant, filed a class-action lawsuit against the data centre. They alleged that Microsoft’s flashy data centre is emitting “unreasonable and excessive noise onto Plaintiff’s properties, thereby causing property damages through private nuisance and negligence.“The noise being generated by “diesel generators and heating, ventilation and air conditioning (HVAC) systems including chillers, cooling towers, air-handling units and condenser fans” is “consistent and pervasive” as per the lawsuit. The residents claim that Microsoft failed to mitigate the noise through “adequate acoustic barriers, shields or walls.”
The strata for data

Last week, a resident in a small town in Southwest Michigan measured the noise level from a nearby data centre from his porch, registering a very irritating 60 decibels. Microsoft’s facility in Wisconsin is emitting a noise “similar to the whirring engine of a freight train parked nearby” around the clock, said Amy Cimbalnik, a complainant in the class-action lawsuit to the outlet. “We heard it 24 hours a day, and eventually realised it was coming from the Microsoft campus,” she added.A Sturtevant resident told regulators the construction pounding ran from “sunrise past sunset daily” for two years, followed by a new 24/7 mechanical hum “similar to the whirring engine of a freight train.” Another resident described “noise all day and night” affecting his sleep, per PC Mag.The tech giant acknowledged the lawsuit, telling the publication that it’s “committed to being a good neighbour in the communities where we build, own, and operate our data centres.”The lawsuit is one in a string of many that tech giants like Microsoft have been facing. At the centre lies the issue of tech companies continuing to encroach on residential areas with enormous and extremely resource-intensive data centres.The backlash has grown into a major bipartisan issue that could even affect the upcoming midterm elections. Despite issues like environmental concerns, massive water consumption and noise pollution, companies claim they need the sprawling facilities to fuel the technological revolution.
Microsoft at work
Microsoft is looking to build a whopping 15 data centres in Mount Pleasant alone.
Microsoft claimed last month that it had already resolved the issue, but considering that the latest lawsuit was filed on July 1, it doesn’t seem to have appeased the upset residents. As per a June 18 update on Microsoft’s official blog, the company said that it was investigating the “source of the sound” claiming that it had “conducted tests and put noise mitigations in place.” Blog entries from mid-April reveal a “tonal humming sound” which was being caused by “cooling fans that are currently operating at high speeds.““Several neighbours confirmed what our independent monitoring showed: that these mitigations fully resolved the issue,” the June update reads. Village of Mount Pleasant communications director Sean Ryan told the outlet that he had not received any complaints since Microsoft made changes to its property in mid-April to “resolve a humming sound.”“Village officials stand ready to respond if people do reach out to us, and will continue to ensure Microsoft is a good corporate citizen and a good neighbour,” he added.

But that seems more like a happy dream and an upcoming nightmare. Microsoft is looking to build a whopping 15 data centres in Mount Pleasant alone. With increasing facilities will arrive increasing noise and the neighbours will have to be prepared for some noise with the company for some litigations.
