Temperature Sensing And Cooling - Compaq iPAQ 1.0 Technical Reference Manual

4.6.4 TEMPERATURE SENSING AND COOLING

These systems feature a variable-speed fan integrated into the power supply assembly. Fan speed is
determined by the power supply's internal sensor.
All systems are designed to use a processor with a passive heat sink. The iPAQ 1.0/1.2 system
includes a system board connector for a processor fan, which, if present, operates in tandem with
the power supply fan. The iPAQ 2.0 system does not provide a connector for a heat sink fan and
therefore should not be upgraded with a processor using a heat sink-mounted fan (refer to
processor upgrading section 3.2.3.).
NOTE: These systems are designed to provide optimum cooling with the cover in place.
Operating a system with the cover removed may result in a thermal condition of system
board components, including the processor.
