"The Zalman ZM-SF3 is a 120mm case fan built from the ground up to cool quietly. The Zalman ZM-SF3 has a unique shark fin design to reduce the turbulence in the air flow for a smoother stream and quieter performance. A high-tech system called ELQ, EverLasting Quiet, is a system that allows the shaft of the fan to spin on a bearing, for a rated 150,000 hours of operation. Rubber padding and silicone pins handle any other possible source of noise that case fans generate in their normal operation. With such a focus on silent operation, it's hard to imagine a better creature to embody than a great white shark as it silently slips through the ocean to feed."

"A research team from the A*STAR Institute of Microelectronics and Nanyang University in Singapore has designed and built a water circulation system to cool stacks of integrated electrical circuits. “The heat must be removed from microchips to maintain a temperature within acceptable limits: less than 100 °C,” explains team-member Navas Khan from the Institute of Microelectronics. Khan and his co-workers therefore focused on a system using circulating water."
