Google's Liquid Cooling
Datacenter-Scale Heat Management
Google notes that water has a thermal conductivity about 4000 times that of air, making it an attractive solution to deal with the cooling demands associated with the current AI boom. That mirrors delidding in the enthusiast world, where PC builders with especially strong stomachs remove heatspreaders (lids) to gain the higher heat transfer efficiency that bare die cooling can provide. Enthusiast setups don’t realize this potential advantage because they use liquid to move heat from chips to a more optimal location for air cooling.
