High Operating Temperature Integrated Fan Heat Sinks
DESIGN FEATURES
■ Industry-leading maximum operating temperature of 90°C
■ Compatible with 35x35 mm and 40x40 mm chipset footprints
■ Common 5VDC @ 0.5 A (max) USB 2.0 fan electrical
specifications
■ Extruded crosscut fins heat sink
DESCRIPTION
The FEX series for 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 low profile to fit
applications with space constraints.
CTS’ eries of hi-temp fansinks maintain superior thermal dissipation for devices that emit high amount
of hea . Our fansinks are available 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.
