NZXT Phantom 630 Case Review

To put this case through its cooling paces we will be using a test system consisting of an AMD FX-8350, Radeon HD 7850 and multiple storage drives. This system allows us to produce a substantial amount of heat and effectively test the NZXT Phantom 630‘s cooling capabilities.

For stress testing we use a mixture of Prime95 and FurMark to create the maximum heat output. Prime95′s ‘Small FFTs’ setting allows us to stress our CPU. FurMark’s ‘GPU Burn-in’ mode creates the maximum amount of load our GPU is ever likely to see.

Test System:

Thermal Performance Test Procedures:

  • The case’s default fan configuration is used to give an accurate interpretation of the out-of-the-box performance.
  • 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.
  • The fans are operating at full speed.
  • We allow the system to idle for 15 minutes and record the stable temperatures.
  • We allow the system to operate under extreme stress for 15 minutes and record the stable temperatures.

Room temperature was maintained at 24°C.


With four fans included in a balanced configuration, the NZXT Phantom 630 offers solid cooling performance for air systems.

With most cases, we recommend users purchase an additional fan to improve cooling performance, but that recommendation isn’t relevant for the Phantom 630.
