Key Features

  • [Radiator Specifications]Model: Peerless Assassin 140 Digital Black,overall size: 140x160x165mm, fan size: 120x120x28mm/140x140x27mm,fan speed: 1850/1500RPM+10%,wind pressure: 2.1/2.09mm H2O Airflow: 82/77.8CFM,Operating Noise:≤29.6/25.6DB(A),Fan Power Supply Interface: 4PIN PWM,the dual cpu fans with the radiator come with S-FDB bearings, which have long-life characteristics to ensure that the radiator dissipates heat efficiently
  • [ARGB Magnetic Digital Display Board] The radiator is paired with a magnetic top cover ARGB digital display board, which can grasp the temperature and occupancy information of the CPU and graphics card, and combined with the TRCC control software, it can achieve the colour switching of the temperature figures
  • [AGHP Heat Pipe Technology] The 6X6mm heat pipe adopts version 5.0 of AGHP technology, which solves the effect of reverse gravity due to the two orientations of standing/lying. Pure copper heat pipes combined with precision reflow soldering micro-engraved copper base optimise the thermal performance of the dual platform for the new generation of dual platform heat generation, avoiding the memory design and recommending memory installation at a height of 44mm or less
  • [Dual Towers Dual Fans Cooling] The cooler is paired with high speed dual fans, a combination of 12cm and 14cm fans, which can easily dissipate CPU temperatures, and the fans feature PWM intelligent temperature control, eliminating the need to manually adjust the fixed speed. Soft corner pads around the fans reduce vibration noise during fan operation
  • [TRCC Software] TRCC Control Centre can freely monitor the parameters of CPU and GPU temperature and occupancy, and the data text can be freely adjusted in colour. The power supply and data communication transmission of the digital display board are provided by the 9PIN USB interface of the motherboard, please ensure the integrity of the wiring before installing the software, which can be downloaded and installed from the official website
  • [Detailed Optimisation] The radiator is paired with SS2 fasteners, multiple specifications depending on the adaptation, compatible with a wide range of CPU models, easy to install and remove, convenient for users to carry out maintenance and upgrades, and easy to install. The included Y-adapter can connect two fans in series with only one motherboard interface
