As industry prepares for the launch of next-generation copper and optical QSFP-DD transceivers, thermal management strategies are critical. The new Molex QSFP-DD thermal solution can cool a range of 15W to 20W in different configurations with a 15 degree Celsius change from ambient temperature. In data centers and telecommunication infrastructure, 56 and 112 Gbps … [Read more...]
Thermal Facts & Fairy Tales: Whatever Happened to the Predicted Data Center Energy Consumption Apocalypse?
As the title indicates, since the middle of the last decade, there have been very pessimistic projections regarding the growth of the total annual energy used by data centers in the U.S. One of them suggested that by 2030, the energy consumption in the U.S. in the IT sector would be roughly 60% of that used by its entire industrial sector. [1,2,3] What was the origin of this … [Read more...]

Managing Cooling Fan Noise In Product Design
ABSTRACT Cooling fan noise is a system property determined as much by thermal and mechanical design and fan selection as by a fan’s acoustical design. While even the quietest fan can be used in a noisy manner, a significant fraction of unpleasant surprises can be avoided. NOMENCLATURE C Numerical constant D … [Read more...]
