NZXT Phantom 820 Case Review

Acoustic Performance Test Procedures:

• We placed our Digital Sound Level Meter one metre away from the case.
• Only the case fans and our power supply are active to accurately isolate the acoustic performance of the case fans.
• The case fans are set to maximum speed.
• The NZXT Phantom 820‘s default fan configuration is: 1x 200mm front intake, 1x 200mm side intake, 1x 200mm top exhaust, and 1x 140mm rear exhaust fans.

Please refer to our KitGuru noise guide for a comparison between the noise levels of this case and everyday scenarios.

With four fans operating at full speed, the NZXT Phantom is a clearly audible chassis. Fortunately, the built-in controller allows users to manipulate fan speeds, and therefore noise output, to a desirable level.
