Tube Length
420 mm

Tube Length

The Tubing Length (mm) indicates how long the tubes connecting the pump to the radiator of the liquid cooling system are, and it directly affects the ease of installation inside the case. A longer length offers more flexibility in radiator placement (e.g., in large cases or in different positions such as the top or front), while a shorter length results in a more “compact” setup but with limited placement options.
Radiator Material
Aluminum

Aluminum
Aluminum radiators are lighter and more affordable, making them the usual choice for AIO liquid coolers, with good performance for everyday use and easy integration into most systems.

Built-in display on the pump for viewing temperatures and statistics. Allows full customization with your own designs or animated GIFs.

Fan Speed (max)

The fan speed determines how fast it spins, affecting airflow and noise level.

  • Low (500-1000 RPM): Quiet operation, ideal for low-noise builds, but with less airflow.
  • Medium (1000-1800 RPM): Balanced performance between cooling and noise.
  • High (1800+ RPM): Maximum airflow, suitable for demanding conditions or overclocking, with increased noise.
Fan Noise Level (Full Load)
31.5 dB

Fan Noise Level (Full Load)

The Fan Noise Level (Full Load) indicates how much noise the liquid cooler’s fans produce when operating at maximum speed, that is, under full load. It is measured in dB(A), and the lower the value, the quieter the operation. This is an important feature for those who want a quiet system, especially in demanding uses such as gaming or rendering where the fans run at maximum.
Air Flow
107 cfm

Air Flow

Airflow (CFM) indicates the volume of air that the fan moves per minute (Cubic Feet per Minute) and directly affects the cooling performance of the radiator. The higher the value, the more air passes through the radiator, contributing to better heat dissipation, although it is usually accompanied by increased noise.
Air Pressure
4.18 mmH₂O: millimeters of water

Air Pressure

Air Pressure (mmAq) indicates the force with which the fan pushes air through obstacles such as the radiator and is measured in mm of water column. The higher the value, the better the fan can penetrate the dense fins of the radiator, making it more efficient for water cooling compared to regular case fans.
