Quiet rackmount servers, designed for noise-sensitive environments
|
eRacks experts design specialized quiet computers, starting with the chassis.
Because of the chassis shape and size, excess heat can be an
problem in rackmount servers. eRacks designers understand airflow and cooling. Addition of a 'silencer kit' to many systems
can easily lead to a heat-induced crash. Each eRacks quiet rackmount server or system is designed from the bottom up, and then must pass
rigorous heat tests, before it leaves the building.
Using a special combination of low-noise chassis fans, fan-placement and other low-noise components including low-heat CPUs and ultra-quiet CPU fans,
eRacks design experts eliminate the familiar noisy computer hum.
The eRacks/QUIET
rackmount server and the
eRacks/SILENCE
tower system are built to be nearly
completely silent.

Our sound-level tests were conducted in a consistent, controlled, low-ambient-noise environment (the "quiet room" baseline above), and were performed with a GenRad precision DB sound-level meter set to consistent settings.
Note: Remember, the decibel is a logarithmic measurement; an increase of 20 decibels represents an increase in input power from 1 watt to 100 watts, or from 1,000 watts to 100,000 watts.

Testimonials:
"
Everything arrived yesterday. I just powered up the computer for the first time
and WOW, I'm impressed, it makes almost no noise now. nicely done! " KW,
Industrial Light & Magic.
"
Just a quick note to say that our new servers are up and running now.
We are very pleased with them - they are really very quiet! The noise
difference between them and the Dell Poweredge 750 servers we originally
used is incredible! Thanks for the great service," TP, from the UK.

Our quietization process is usually done on a custom basis, and is dependent on the tolerable noise level for
the particular application, and the system's configuration. Please call or email us with your computational
requirements, and we will put together a configuration and quote for you.
Some of the systems that are QuietByDesign or can be quietized include:

eRacks offers more flexibility in configuration at a better price!
