CoolerMaster QUBE 500 heat dissipation test

The QUBE 500, with its integrated 120mm rear fan, underwent a heat dissipation test using a 240mm water cooling system mounted on the top for exhaust, without any additional fans. The test focused on the Intel Core i9-14900K, a processor known for its high power consumption, hence the suggestion to use power consumption wattage as a benchmark for heat dissipation.

Test Setup Details:

  • Processor: Intel Core i9-14900K
  • Motherboard: ASUS ROG Strix Z790-A GAMING WIFI II
  • Graphics Card: ASRock Radeon RX 7800 XT Steel Legend
  • Operating System: Windows 11 PRO 23H2
  • Radiator: CoolerMaster MasterLiquid 240L Core ARGB
  • Power Supply: CoolerMaster V1100 SFX

During the test, the i9-14900K reached a temperature of 93 degrees Celsius under a 250W power consumption in the AIDA64 CPU, which exceeded expectations for a 240mm water cooling system. Without additional fans for the water cooling, the graphics card maintained a temperature of around 60 degrees Celsius.

The QUBE 500 offers various cooling options. The author recommends an air-cooled radiator, as the top-mounted water cooling is significantly affected by the graphics card’s heat. A 280mm water cooling system on the side or front is advised for optimal CPU cooling, as it intakes air externally and isn’t influenced by the graphics card’s heat. For less demanding CPU cooling requirements, top-water cooling is a viable option.



The actual assembly of the QUBE 500 is notably straightforward and not troublesome. Following the official instructional video, components can be installed while assembling the case, leading to an almost seamless building process. One of the key highlights is the absence of unnecessary space or obstructions, contributing to a smoother assembly experience. This ease of DIY assembly is a major advantage of the QUBE 500, allowing enthusiasts to enjoy the process without undue difficulty.

The QUBE 500 utilizes a front-mounted power supply configuration in its standard mode. This setup means that the top-mounted water cooling system, power supply, and graphics card must share the total height within the chassis. Consequently, if a longer power supply is installed, it could potentially reduce the available space for the cooling radiator and graphics card. However, in practice, if the length of the power supply is kept around 14cm, it generally does not interfere with the compatibility and wiring space between the radiator and the graphics card.

While some might view the inability to accommodate a 360mm radiator as a drawback, given the case’s size, the unique near-square shape of the QUBE 500 makes it distinctive. This design may not appeal to everyone, but those who appreciate its form factor will likely find it highly satisfying.
