OptiPlex 740 - Power Efficiency (cont)
Efficient, Reliable BTX Design
All OptiPlex models are built on the thermal-efficient BTX
form factor and packed with additional features that help
ensure quality and thermal reliability.
• Enjoy better reliability and quieter, cooler operations:
– Dell BTX chassis, power supply and motherboards are
uniquely designed to manage heat throughout the system
– HyperCool™ thermal-management technology uses variable
speed fans for additional cooling, while using less power and
generating less noise
– New Ambient Thermal Sensor — Measures the incoming
ambient air temperature to appropriately control internal
cooling and helps improve thermal reliability
– More thermally robust components — Going beyond
industry standards by defining more stringent temperature
specifications for capacitors and hard drive casings to
improve thermal reliability
• Ensure a seamless user experience — Hardened power
supplies offer brown-out circuitry and line-surge protection
to help minimize stress on power supply and provide black-
out protection
Continued design improvements
• Thanks to our “closed-loop” cycle of improvements, the
next generation of OptiPlex platforms will deliver even
further quality and reliability enhancements. In addition to
the thermal-efficiency features mentioned above, we’ve
added vibration-dampening features to the hard-disk drive,
which help offset unbalanced media for better acoustics
and reliability.
