A Principled Technologies test report 2
Workstation heat, sound, and power usage: Lenovo ThinkStation
D30 vs. Dell Precision T7600
WHICH WORKSTATION DELIVERS RELIABILITY, POWER-
EFFICIENCY, AND A PLEASANT WORK ENVIRONMENT?
A workstation that generates more heat and noise and uses more
power than necessary can be more prone to system failure, can be distracting
and uncomfortable for workers , and can boost electricity bills—both because of
the power the system itself draws and the power that additional air
conditioning uses. To determine how two workstations compared on these
fronts, we measured the heat, noise, and power consumption of the Lenovo
ThinkStation D30 and the Dell Precision T7600.
We performed the tests while the two systems were idle and again
while they were running a heavy workload that consisted of two benchmarks
stressing each system’s hard disk, processor, and memory.
Figure 1 presents highlights of our test results.
