[2000RPM PWM Fan] The heatsink cooler is equipped with a performance-level fan speed of 2000RPM,and the cpu fan has a PWM function,which can adjust the speed according to the temperature of the motherboard,without manual adjustment.UL CLASSA safety insulation grade industrial grade PBT+PC material,as well as the S-FDB bearing of the fan,can well solve the problem of fan blade shaking in hoisting mode.Silicone corner pads around the fan can reduce the noise caused by rotation to a certain extent

[151mm Heat Dissipation Height] The overall height of the heatsink cooler is 151mm, which is compatible with most cases without sacrificing heat dissipation performance, making the heatsink more compatible. The top cover design of the digital screen improves the overall appearance, so that the high heat dissipation function and aesthetics of the radiator are combined

[AGHP Heat Pipe Technology] 4x6mm heat pipe adopts AGHP upgraded 4th generation technology, which solves the influence of anti-gravity caused by the vertical and horizontal mounting directions. Seiko heat pipe's direct contact process, HDT direct touch fine bottom surface treatment, combined with nickel-plated anti-oxidation heat pipes, so that the heat dissipation effect is improved

[ARGB Divine Light Synchronization] The ARGB of the pwm fan is synchronized with the 5V 3pin on the motherboard to achieve light synchronization. The colourful soft light effect of this ARGB fan provides rich lighting effects while efficiently dissipating heat, cooling the CPU temperature while realizing the colour changing transformation, combining the performance with the colour perfectly.

[Digital Screen Software Description]The power supply and data communication transmission of the digital screen are provided by the 9-pin USB interface of the motherboard. Before installing the TRCC software, please confirm that the wiring is complete. The software can be downloaded from the official website. After installation, it will automatically boot up with the computer and stay in the background. Do not turn off or exit
