Man Prakash Gupta and Satish Kumar G.W. Woodruff School of Mechanical Engineering, Georgia Institute of Technology INTRODUCTION Due to the growing demands of higher performance and faster computing, the number of cores in a microprocessor chip has been increasing consistently. The transition from single core to multi-core technology has already been observed in the past few … [Read more...]
Use of JEDEC Thermal Metrics in Calculating Chip Temperatures (without Attached Heat Sinks)
Bruce Guenin Assoc. Technical Editor, Electronics Cooling INTRODUCTION JEDEC single-chip package thermal metrics are widely used as a means of characterizing the thermal performance of semiconductor packages. They correlate the peak temperature of a uniformly-heated semiconductor chip (the junction temperature, TJ) with the temperature of a specified region along the heat … [Read more...]
Hybrid Liquid-Air-Cooled Heat Sink for Extreme Environments
CoolClouds, Inc. has announced the availability of a new class of heat sinks for use in high performance computers or extreme environments starting mid-Q1 2014. According to the company, SuprCool-PC is the first “in-chassis” heat sink to cool more than 300w in the latest Intel and AMD processors without hot spots at 65°C case temperature in 25°C ambient. Comparable in size to … [Read more...]
Bitcoin Mining Boosts Interest in Liquid Cooling
A journalist's recent visit to a secret Hong Kong Bitcoin mining facility reveals some of the newer cooling techniques in use to keep server temperatures from skyrocketing. Introduced in 2009, Bitcoin is an open-source peer-to-peer electronic payment method generated through the process of “mining,” in which computers are awarded bitcoins for finding the solution to specific … [Read more...]
