House passes bill to increase federal data center efficiency

The aim of the legislation is to increase efficiency of federal data centers. According to a statement from Rep. Anna Eshoo’s office, data centers account for nearly 2 percent of all U.S. electricity consumption and 10 percent of the federal government’s electricity consumption. Improving energy efficiency at the federal government’s nearly 2,000 data centers could significantly reduce the government’s energy use and save billions in taxpayer dollars....

Non-spill connectors create liquid cooling confidence 

In the liquid cooling space, quality is paramount. The use of high-performance thermoplastic quick disconnects allows servers to be connected to or disconnected from a cooling system without shutting down or affecting neighboring servers, creating hot-swappability, leak-free performance, and simplified hardware maintenance.

Why liquid cool your NVIDIA Tesla K80?

High-end GPU cards have become an indispensable part of modern computing. However, these cards produce significant amounts of heat, and conventional air cooling systems often cannot cool them effectively. Increasingly, consumers are turning to liquid cooling systems, such as Ebullient DirectJet systems...

Why is heat a problem for computer chips?

Heat is the ultimate enemy when it comes to high-speed processing. The constant drive for a few hundred more megahertz pushes the cutting edge of computing, but it must always contend against the energy released by so much power flowing in such a tiny space.

Boiling is surprisingly complex

The boiling point of water is 212 °F (at atmospheric pressure). But in reality, bubbles of water vapor do not develop in water until its temperature is between 212.1 and 572 °F, depending on the circumstances...

What is direct-to-chip liquid cooling?

Direct-to-chip liquid cooling is a highly efficient cooling technology for data centers. In most data centers, direct-to-chip liquid cooling can reduce cooling costs up to 75%.  In addition, it allows operators to install more servers per rack, since gaps between servers for airflow are not needed.  For most customers, this means consolidating two or three racks into one and freeing up floor space for future expansion.  Often, this means avoiding large capital expenses associated with constructing new data center space.

How can boiling cool servers?

To many, it’s counterintuitive that a boiling liquid can cool servers. Afterall, the most tangible example of a boiling liquid is in the kitchen, where the boiling point of water is 212 °F, or 100 °C, which is pretty hot to the touch....Our cooling systems use Novec 7000 (HFE-7000)...
