Intel's "Active heatsinks" My guess is they run "real" hot and Intel doesn't want amateurs screwing around with the cooling. (warranty, customer care) techweb.com May 17, 1999, Issue: 1061 Section: Product Week -------------------------------------------------------------------------------- Active, passive cooling entries can take Pentium III's heat Concord, N.H. - Eyeing the cooling requirements of Intel Corp.'s new Pentium III microprocessor, Aavid Thermal Products Inc. has launched a family of heat sinks that have cross-cut cooling fins to support omnidirectional airflow. The company has also unveiled heat sinks targeted at the sub-$1,000-PC marketplace. "The changes in packaging in the Pentium III require new cooling products," said Aavid marketing manager Christopher Chapman. Pentium III processors need a variety of passive and active heat sinks with a multitude of clip options to accommodate OEMs' various manufacturing-line preferences, he said. "As system power and integration increase, PCs and servers require more exacting thermal designs," said Craig Johnston, vice president of Aavid Thermal Products' sister company, Applied Thermal Technologies. "These thermal designs must provide improved thermal spreading characteristics, increased chip contact pressures and upgradability to active solutions when demanded by system-flow bypass issues." One set of passive and fan heat sinks-part numbers 030102 and 030809, respectively-targets desktop PCs. For workstations and servers using the Xeon Pentium III, Aavid also offers a passive heat sink (part number 027846) and a fan heat sink (the 030943). The passive desktop solution uses Intel-recommended plastic clips (sold separately as Aavid part number 030103) and Chomeric's T443 interface material. Fan heat sinks have a clipping mechanism that lets a larger fan provide proper CFM at lower speeds, minimizing acoustical noise. Aavid offers the clip with the fan heat sink as one unit. Aavid offers the clip with the fan heat sink as one unit. Independent shock and vibration tests meet specifications for speeds up to 550 MHz, Aavid said. For server systems, a phase-change interface material is preapplied to Aavid's passive heat sink for quick assembly using off-the-shelf hardware. The heat sink for servers uses a dc fan applied to the heat sink and preapplied interface material. In quantities of 10,000 the unit price for the 030102 is $2.22, the 030809 is $5.14, the 027846 is $9.13 and the 030943 is $11.83. All are in volume production. For sub-$1,000 PCs, Aavid offers heat sinks for maximum cooling performance in minimal configurations. They also use the cross-cut cooling fins for omnidirectional airflow, along with fans that the company said exceed industry requirements for performance, cost, reliability and noise. In lots of 10,000, the pricing ranges from $1.87 to $4.95. The parts are in volume production. Call (603) 224-9988 www.aavid.com EETInfo No. 608 Copyright ® 1999 CMP Media Inc.
