Using air to cool electronic equipment is naturally inefficient. It takes significant energy to effectively remove heat from servers with air. By comparison, immersion cooling in liquids like water can conduct heat far more effectively.
The problem has been finding a liquid that won't conduct electricity or damage delicate electronic devices. Intel Corp. has just finished a year-long evaluation of immersion cooling in which it submerged a server into a nonconductive bath of mineral oil. Research like this could redefine how we cool our servers and allow for even faster clock speeds, making air-driven heat sinks obsolete. In fact, it has the potential to change the entire texture of data center cooling schemes.
