Not a first for Finland
This is actually not a first for Finland. The LUMI EuroHPC pre-exascale computer is hosted by CSC in a data centre in Kajaani and its waiste heat is also used to heat the city.
Finland is very well suited for such cooling techniques. Some IT equipment nowadays is designed for nearly 100% hot water cooling. When it is cold, the heat can be used to heat nearby homes, and as Finland has a very moderate climate year round free cooling can be used to remove the remaining heat when it cannot be used for heating.
