Yes, but the heat will still likely need boosting by about a further 10 degrees either at the source or end user.

DC inlet is 45°C, outlet is 55°C assuming a 10°C ΔT. By the time that's travelled 500m–1km through pipework you've lost a few degrees, so you're arriving at the HIU at maybe 50–52°C. The home radiator circuit then takes that down by around say 12°C, returning ~38°C. Factor in pipe losses on the return leg and you're back at the data centre with maybe 35°C inlet rather than 45°C — meaning the DC output is now only 45°C rather than 55°C, and the whole system gradually degrades each cycle. You could address this by mixing some hot output back into the return to keep the DC inlet stable at 45°C, but eh.

I grew up in Northern Virginia, (of AWS US-East-1, MAE-East, and Equinix fame), where there are more data centers than anywhere else in the world, and I never heard organized opposition to them until the last couple of years. They were mainly viewed as a way for Loudoun County to build their industrial tax base without the downsides of having industrial workers, and allowed them to consistently lower property taxes while having excellent schools. Data centers are unsightly and use electricity and water, but so does literally any kind of industrial facility. They are also pretty quiet, if you exclude the ones using on site gas turbines for electricity.

Property values have consistently gone up in that region for decades, and are up to $6 million an acre if there's enough contiguous land to put another data center on.

Many of the people complaining about datacenters would also complain about literally any kind of development.

I’ve been to datacenters, but not the huuuge ones people seem to talk about in the context of AI. They are noisy inside (due to air cooling, which is largely avoided by the tech in the OP), but they’re entirely unremarkable outside compared to any other commercial or industrial building. Computers are not inherently loud, nor is power conversion.

Power plants are all over, even in populated areas. They’re not so bad either (except perhaps coal).

There is no fundamental reason that datacenters need to be especially unpleasant to their neighbors.

>the way we heat up the earth right now, i don't think you have to worry about heating

Nearly 10x more people die from the cold than from the heat.

"...9.43% of global deaths were attributable to non-optimal temperatures, with 8.52% from cold and 0.91% from heat."

Do you? I live at 4th and Brannan and there was one just off 3rd and Brannan in San Francisco. It was shut down when hosting.com sold it off but I didn't notice it while walking by then and I don't notice it while walking by now.

My GPUs at Hurricane Electric in Fremont are also completely unnoticeable outside the building. Inside, when I'm working at the cabinets it's obviously deafening. Outside you wouldn't even know. Realistically, the predominant sounds at my home are from the traffic on the Bay Bridge so it's nice when there's congestion because it's quiet.

Honestly, I wish there were more urban datacenters. It's getting quite annoying having to make a 1 hr trek to Fremont every time I want to rack a new server.

Noise is a design choice and could likely be legislated away. Reject heat is different than heating from greenhouse gas effects that are “heating the planet”.

No one bats an eye when an air conditioner runs.

It sounds like with this liquid cooling, they won’t need the fans?

Couldn't imagine living with the ~55dBA noise literally all the time

Coldest month average temperature where I live is around -7C, with peaks of -35C. Climate change is not going to increase that average, more like decrease. Typically, of course, electricity price is the highest during that month too.

I think we are going to need heating.

>Do you live near a datacenter? Property value goes down, constant humming

I don't live next to one but I'd take constant humming over the constant stop/go traffic noise, honking, squeaky brakes, slamming doors and revving engines I now have on my western side of the apartment, thanks to the unemployment office the city opened on my street not too long ago.

So how come constant humming is somehow an illegal nuisance, but we've been expected to put up with the much more annoying urban traffic noise for decades just fine?

My parents apartment have constant humming anyway thanks to the HVAC system on the roof of the nearby supermarket and white/brown noise is far more tolerable and easy to tune out than traffic noises.

So what, winters would be no more? Snow will disappear, no more ice-men and christmas trees, and subzero conditions in general, too?
