We take the issue of noise very seriously at KitGuru and this is why we have built a special home brew system as a reference point when we test noise levels of various components.
Why do this? Well this means we can eliminate secondary noise pollution in the test room and concentrate on components we are testing. It also brings us slightly closer to industry standards, such as DIN 45635.
As this can be a little confusing for people, here are various dBa ratings in with real world situations to help describe the various levels.

Noise was measured from half a meter away.
The Qnap TS-259 Pro+ is clearly audible, though never loud enough to be intrusive. The only situation we would warn against would be having this unit close to your bed at night as the fan noise might prove irritating.
We measured power from the socket with 2 x 1TB Samsung HD103SI hard drives installed.
The TS-259 Pro+ requires 16 watts when idle and 24 watts when active, reasonably efficient figures for a two 1TB configuration.
Time to test the cooling system. Our room ambient temperatures are 23c which is a reasonable temperature for most people to work and relax within.
The drives remained between 2 and 5c above ambient at all times with average results recorded above. The cooling system, although louder than many, ensures the best drive temperatures.
Built like a tank, as always. love their products.
compares well against the synology 710 unit, a little slower, but not really noticeable, but more suited to business market with design rather than home market. room for both I think.
QNAP, our business uses a mixture of their older products, nice to see them sprucing up their performance with this generation.
excellent product, bit much for what I need at home, but pricing seems good.
QNAP and Synology certainly are going toe to toe. both are really delivering this year so far. its nice to see a company drive another harder
