Datacenters Could Work as Well with Less Cooling

Datacenters are normally kept at temperatures between 20C and 25C (68F and 77F).

Cooling can account for a third of a typical datacenter’s total energy consumption.

Shengwei Wang and colleagues at the Hong Kong Polytechnic University found running datacenters at higher temperatures than they currently operate could reduce their energy consumption significantly while maintaining computational performance.

The researchers programmed a computer model to simulate information technology equipment's performance at different temperatures in 57 cities worldwide.

They learned running servers at 41 degrees Celsius (106 degrees Fahrenheit) could save up to 56% of the energy used for cooling compared with those operating at 22 degrees Celsius (72 degrees Fahrenheit).

This approach would yield the greatest energy savings in sites whose higher ambient temperatures require the most cooling, such as Brazil or West Africa, according to the researchers.
