Tom's Reviews Expensive, Noiseless Case
hakker writes "Toms Hardware Guide is running a review of a new case that claims it provides noiseless computing. The TNN 500A case from Zalman Tech is fanless (including PSU), and uses a bunch of heatpipes to move heat outside of the case from sources inside the system. Potentially costing as much as $1400, how much is your peace and quiet worth?"
...in three easy steps.
1. Antec Performance One P160 case.
2. Nexus PSU, fans and CPU heatsink and fan.
3. Samsung SpinPoint series of HDDs.
Zalman's products aren't bad but, IMHO, Nexus' are superior.
Oh, and either ditch the jet engine that masquerades as a graphics card with something quieter or replace its fan too.

The AC is actually right, most humans can hear sounds down to about 0 decibels. It's no accident that it's scaled that way.
The decibel scale is logarithmic, which means a 70dB sound has 10 times the intensity of a 60dB sound. If you double the intensity, on the decibel scale you only go up 3db. So put 2 30dB case fans in a computer, and the total from them would be 33dB, not 60dB.
It's also possible to have sounds in the negative decibel range, it's just we can't hear them.
To answer the question more directly, 28dB is considered the noise level of a quiet room, so less than that is accepted as "silent." If you see a dB(A), the (A) means that an A-weighted filter was used with the dB meter. reference
