These videos blow me away. As expensive as it is to maintain air cooled server racks in large data centers, everyone is looking for a solution. Well just as air cooled Volkswagon beetles gave way to water cooled, so now (similarly) is the data center.
These guys use a non-electrically conducting mineral oil to cool the servers.
1200x better thermal dissipation than air. Hard to believe, but this is pretty cool (pun intended). Imagine us consultants actually getting to work in data center that is normal room temperature without having to dress like an eskimo!
