Microsoft is now submerging servers into liquid baths

This isn't really new. Here is an article in early 2017 [1], and I remember there are DataCenter trailing it in 2016. OVH has always been water cooled although they are not submerging it.

The reason I remember it hasn't caught on was because the cost and benefits does not out-weight Air Cooling. Where it is a well understood design and DataCenter construction does not need new design and thoughts input. With future Chiplet or Tiles design we could easily hit a chip with 1000W TDP along with 1000W GPGPU and TPU sitting close.

May be it finally make sense to took at look again.

> This type of liquid cooling has been used by cryptominers in recent years to mine for bitcoin and other cryptocurrencies. This method inspired Microsoft to trial its use over the last few years, using it to test against spikes of cloud demand and intensive workloads for applications like machine learning.

I've seen this used to enable cost-effective crypto mining in areas with cheap electricity and hot weather. I thought the expense of liquid-cooling everything outweighed the benefits for data centers, but maybe that's not true anymore.

I love the "cool factor" of the tech, but I worry about the increased use and eventual disposal of PFC liquid as this approach becomes more widespread
