Pros & Cons

👍 Pros

  • Offers wide compatibility with numerous Intel sockets (1150, 1151, 1155, 1156, 1700, 1851, 1200) and AMD sockets (AM4, TR4, sTRX4, AM5).
  • Features a 240mm radiator size with dual 120mm fans, providing efficient heat dissipation for your CPU.
  • Constructed with a combination of aluminium and copper heatsink materials for optimal thermal conductivity.
  • Designed as an all-in-one water cooling system, simplifying installation compared to custom loop setups.
  • Leverages water cooling technology, which can offer superior cooling performance over traditional air coolers, especially for high-TDP CPUs.
  • The integrated pump and radiator design minimizes leakage risks associated with separate components.

👎 Cons

  • The all-in-one design, while convenient, means components are not user-serviceable or upgradable like custom water cooling loops.
  • Radiator size of 240mm might not be sufficient for extreme overclocking scenarios on very high-end processors.
  • Installation requires adequate space within the PC case to mount the 2x120mm radiator and fans.
  • The performance can be influenced by ambient case temperatures, requiring good overall system airflow.
  • Fan noise levels, while not specified, can be a consideration for users prioritizing a silent PC build.
  • The heat sink materials are listed as aluminium and copper, which is standard, but the specific type of fans is not detailed.
