Product Description

Manufacture # Cooler Master | Model # TD300-KGNN-S00


The included HUB features 5 ARGB and 4 PWM ports and facilitates cable management in the system, allowing you to conveniently control fans with a single connector for power and PWM signal and another for ARGB signal.



  • The top panel is entirely removable for improved access to the components during assembly. Ease of use also facilitates the mounting of cooling solutions such as fans and radiators.
  • Hardware, custom-loop cooling, and the pure pride of the builder is shown in panoramic view through an edge-to-edge tempered glass side panel.
  • Support for up to six fans and front, top, and rear radiator support ensure that performance is not compromised.
  • Support for up to a 344mm graphics card, a 166mm CPU cooler, and up to a 325mm PSU in length provides room for upgrades to stay ahead of the game.
  • The drive cage can be shifted towards the front to accommodate for PSU space, backwards to provide additional radiator space, or even completely removed.
