Because of recent advances in high-end CPUs and computer parts, PC/laptop users can now enjoy a level of performance that could only have been dreamed about several years ago.However, high-speed multi-GHz CPUs and advanced  videocards don't come without a cost.They bring extra heat to already steamy systems.

Failure to keep system temperatures within a certain range can deteriorate system performance and cause system-wide failures.

ADDA's cooling fan AD2510, winner of CETRA's 2001 "Symbol of Excellence," may be the solution to thermal woes.

David Chiang, general manager of ADDA's Thermal Department said, "Stand-alone cooling devices succeed only in transfering heat to other devices.Therefore, an integrated system cooling mechanism is an essential change to allow stable performance."

AD2510, known for its tiny size, can offer single spot cooling for PCs/laptops and overall system cooling for compact notebooks.

Air bearing technology, released as "Hypro Bearing" by ADDA in 2000, solves the friction problem normally found in sleeve axial bearings. In operation, such design generates less noise and offers longer life.

This new air bearing technology requires substantial overhead, requiring an aero dynamics research team and refined plastic extrusion unit, both of which cost a lot.

Tim Ho, vice general manager of ADDA's Thermal Department, said, "Applying air bearing technology renders obsolete our current machinery, because it requires more accurate molding methods to satisfy aero-dynamic design specifications."

ADDA's market policy focuses on working with tier one PC/laptop manufacturers rather than going straight to the consumer market.

"The reason for such a policy is so we can concentrate on achieving higher quality without worrying about satisfying finicky consumer design preferences," explained Chiang. "The manufacturers can also offer economics of scale."
Taiwan-based ADDA incorporated in 1977 and now has manufacturing bases in Taiwan, mainland China and North America, with a total production capacity of 650 million units per month.

ADDA also plans to go public in both Taiwan and mainland China and expects to reach a goal of 70 percent production automation by 2003.

The brushless cooling fans are currently on display at the Taiwan Showcase of Excellence Hall on the second floor of the Taipei World Trade Center.
