Workstation heat, sound, and power usage: Lenovo
ThinkStation S30 vs. HP Z420 Workstation
LESS POWER USED IS BETTER
A workstation that uses less power saves you money when the electric
bill comes. As Figure 3 shows, the Lenovo ThinkStation S30 used less power than
the HP Z420 Workstation—28.0 percent less when the systems were idle and
14.5 percent less when they were under load. We used an Extech® Power
Analyzer to measure power consumption while the systems were idle and under
load.

IN CONCLUSION
A workstation that runs in a quiet and cool manner and uses less power
is a great boon to workers and the companies they work for. In our tests, both
when idle and when under load, the Lenovo ThinkStation S30 ran more quietly
and at lower surface temperatures than the HP Z420 Workstation and used less
power. These findings make the Lenovo ThinkStation S30 an excellent choice for
those who want to provide a reliable, comfortable work environment while
using less power.
