Common IT wisdom would have us believe that the ideal temperature for a server room be between 13 and 16 degrees Celsius (°C), but recent tests and reports are shedding light on this myth, demonstrating that it does not need to be as cool as we once thought. Among others, Sun Microsystems recently discovered that servers can actually work quite well in much higher temperatures and humidity. Likewise, Google has now suggested that server farms be kept between 21°C and 26°C.
But these IT giants aren’t the only ones playing with their thermostats. Microsoft has recently achieved AUS$380,000 in one of their Silicon Valley data centres by adjusting the thermostat up by 2 degrees C, and HP is expecting to save over AU$12 million annually by making similar changes.
Potential Savings by implementing the tip
According to Consumer Reports, for every half of a degree Centigrade that you raise your thermostat temperature setting, you’ll save at least 3% on your cooling utility bill.
