FAN HEAT SINKS - FHS-090 SERIES
High Operating Temperature Integrated Fan Heat Sinks
DESIGN FEATURES
■ Industry-leading maximum operating temperature of 90°C
■ Compatible with chipset footprints ranging from 21x21 mm to
45x45 mm
■ Total heights from 16.1 mm for low profile applications to 44.6
mm for lowest thermal resistance
■ Forged and extruded versions available
■ Choice of elliptical, round pin, and plate fin styles
DESCRIPTION
The FHS-090 Series of integrated-fan heat sinks is uniquely designed to absorb and disperse heat away from
high temperature devices while offering key features such as an operating temperature range of -10°C to 90°C,
calculated MTTF @ 90°C: 86,858 hours (GEM, 90% confidence) and various package sizes to best fit the
application. Thermal resistance values range from 4.07°C/W to as low as 1.24°C/W.
These new fansinks can maintain superior thermal dissipation for devices that emit high amount of heat. CTS’
fansinks are available in a wide range of footprints and fin heights which make them suitable for many elevated
temperature applications such as component testing, burn-in, high density servers, high- speed computing and
video, and use in areas where the system airflow is constrained.
