[Good Heat Dissipation] The CPU cooling is mainly composed of a digital version of a dual tower + double fans + a magnetic top cover. The 6 pure copper heat pipes and the pure copper base can well contact the temperature of the CPU, with the combination of a high speed of 1850RPM, the radiator has a good heat dissipation effect

[CPU Cooler Specifications] Model: Peerless Assassin 120 Digital Black, overall size: 138x125x162mm, fan size: 120x120x28mm, fan speed: 1850RPM+10%, wind pressure: 2.21mm H2O, air volume: 88.89CFM, operating noise: ≤25.6DB (A), fan power supply interface: 4PIN PWM, the radiator is equipped with dual fans with S-FDB bearings, which have the characteristics of long life and can ensure long-term heat dissipation of the cpu radiator

[AGHP Heat Pipe Technology] The 6X6mm heat pipe adopts the 5.0 version of AGHP technology, which can solve the inverse gravity effect caused by standing/lying. The pure copper heat pipe is combined with the base of the precision reflow soldering micro-carved copper bottom, targeting the characteristics of the new generation of dual-platform heating,and optimizes the heat dissipation performance of the dual-platform

[162mm Height] The overall height of the heatsink cooler is 162mm, which is compatible with mainstream ATX chassis. The radiator adopts an overall black style, and the digital display board design of the magnetic top cover opens up a new world of heat dissipation, combining the high heat dissipation function of the radiator with innovative technology. The overall design of the dual tower and dual fans is compatible with the installation of high-capacity memory and graphics cards

[Wide Compatibility] The cpu cooling is compatible with platforms: AMD: AM4/AM5 and LGA1851/1700/1150/1151/1155/1156/1200, and comes with dual-platform mounting clips, which can be well installed on the corresponding platform. It can be installed according to the instructions or installation tutorial. (Note: The installation of the AMD platform requires the use of the original backplane of the motherboard, which is not included with this product)
