The meteoric rise in cooling requirements of commercial computer products has been driven by an exponential increase in microprocessor performance over the last decade. The conventional way to cool microprocessors has been to utilize air to carry the heat away from the chip, and reject it to the ambient. Air cooled heat sinks are the most commonly used air-cooling devices with … [Read more...]
Calculation Corner: Transient Thermal Modeling of a High-Power IC Package, Part 1
Part II can be found here. There is an increasing need for calculating integrated circuit temperatures during conditions of changing chip power. Varying computer workloads and the implementation of power-saving strategies are leading to greater variability in chip power levels than in the past. As reliability requirements get more stringent there are growing concerns about the … [Read more...]
Breakthrough Thermal Material System to Enable Faster Computing
Scientists in GE’s Global Research Center have demonstrated an advanced thermal material system that could lead to faster computing and higher performing electronic systems. They have fabricated a prototype substrate that can cool electronic devices, such as a laptop, twice as well as copper. The development of GE’s prototype substrate, which utilizes phase-change-based heat … [Read more...]
Little Layer Cakes of Crystal Could Help Shrink Computers
In research aimed at making computers even smaller and more powerful, two engineers at Duke University have made headway in the quest to control the beams of light generated by tiny lasers. The two Duke scientists - Nan Marie Jokerst, professor of electrical and computer engineering, and Ph.D. student Sabarni Palit - found solutions that could prove particularly useful in … [Read more...]
Graphics Card with Thermal Design Offers Quiet Performance
Graphics card and mainboard manufacturer MSI recently unveiled its N560GTX-Ti Twin Frozr II/OC graphics card featuring the Twin Frozr II Thermal Design. An appraisal by BenchmarkReviews.com determined that “the Twin Frozr II cooling system is a well proven package that kept the GF104 GPU quite cool, even during stress testing.” The thermal interface material (TIM) was very … [Read more...]
