Fanless DVRs are now possible due to new hard drives from Seagate that consume much less power and produce less heat. This allows DVRs to be built without cooling fans, reducing costs for manufacturers. Seagate's Pipeline HD drive uses 40% less energy and is optimal for building fanless DVRs. Adopting this technology allows manufacturers to build fanless DVRs, which consumers demand for environmental and acoustic reasons, and gives manufacturers a competitive edge.
Introduction to Intelligent Power ManagementAdaptec by PMC
Adaptec Intelligent Power Management (IPM) allows disk drives in servers to reduce power consumption by lowering revolutions per minute or stopping spinning altogether during periods of inactivity. It intelligently buffers data to avoid frequent spin-up/down cycles that waste energy. IPM can be built into Adaptec RAID controllers and reduces the energy needed to power and cool disks by up to 70%. Larger server installations with many disks can save thousands per year on energy costs and cooling requirements through IPM.

Fanless DVRs
Increasingly, consumers worldwide are
demonstrating a firm commitment to adopting a
more environmentally friendly, or “green” lifestyle.
In the consumer electronics market, demand
is on the rise for devices that use less power.
Consumers want to actively promote energy
conservation through their individual purchase
decisions and reduce their annual household
spending on electricity. Both of these trends favor
the continuation of robust consumer demand for
energy-efficient devices, including fanless DVRs.
DVR and set-top-box makers can take advantage
• Harddrive isolated from other heat-producing components by
of this opportunity to diversify their product

offerings and reach new consumers—while
• Hard-mount design allows conduction cooling to the chassis
structure, in addition to convection expanding capacity to capture increasing future
demand. The Seagate Pipeline HD drive, which
Figure 1: Hard Drive Design Recommendations
features operational power consumption as
low as 4.7 watts and storage capacity up to
1 terabyte, is well suited to the fanless DVR
application, a fact confirmed by extensive testing.
