Thermal and acoustics
Optimized thermal management makes the PowerEdge T20 cool and quiet. Benefiting from a smart
cooling thermal control algorithm, the T20 offers both high performance and quiet acoustics across
a wide range of ambient temperatures (5°C ~ 35°C). Though the fan-induced sound is inevitable for
cooling purposes, it is controlled to be smooth and quiet. In a typical office environment (~45dBA),
the sound is almost unnoticeable.
