We take the issue of noise very seriously at KitGuru, and while I don’t have access to the industry’s best equipment I have done everything possible to ensure this test is as accurate as possible.
Today to test this chassis we have set our Digital Sound Level Noise Decibel Meter Style 2 one meter away from the case. The room rates as 23dB (A) before powering on the system.
We then turned our system over to the onboard graphics card, and temporarily turned the Antec 920 fans off. This leaves us with only the 1 included case fan and some noise from the 12cm PSU fan.
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.
