NZXT Phantom 630 Case Review


Acoustic Performance Test Procedures:

  • We placed our Digital Sound Level Meter one metre away from the case.
  • The case fans are set to maximum speed.
  • The CPU cooler’s fans are deactivated.
  • The NZXT Phantom 630‘s default fan configuration is: 1x 200mm front intake, 1x 200mm side intake, 1x 200mm roof exhaust, 1x 140mm rear exhaust.

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

A positive in terms of cooling performance, the Phantom 630’s four fans don’t do it many favours in regards to acoustic output. At 100% fan speed, the case’s noise output was measured as 42.5 dBa. While this isn’t an irritating level, it is most certainly noticeable and would have us reducing the fan speed when maximum cooling performance isn’t necessary.
