Most Efficient Pump
Latest motor technology and smooth tubes offer top performance at only 2 watt power consumption.
Every Unit Performs the Same
A concentric CNC guarantees a smooth and even surface. Thus a consistent series production quality is guaranteed and every unit performs exactly the same.
Optimal Heat Dissipation
Four low noise 120 mm fans mounted on opposite sides of the radiator provide a great airflow. The first two fans push air through the radiator, the second two fans pull the air through it. Controllable with PST function to adjust the fan speed based on CPU temperature. 

Quiet and Powerful Fan
We fully designed the F12 fan with CFD (Computational Fluid Dynamics) software and optimized it for high airflow. From all fans tested in our air tunnel and anechoic chamber the F12 offers the highest airflow at a given noise level - by margin
All fans tested at 800 RPM, in anechoic chamber and wind tunnel.
MX-4
Ready for 16 Cores and Overclocking
We pack a bag of the leading thermal compound, enough for two applications. The MX-4 guarantees to dissipating heat from your CPU in the quickest and most efficient way.
With the Liquid Freezer 240 You are! Deals with up to 300 Watts TDP - at almost complete silence.
Long Service Life
The Fluid Dynamic Bearing comes with an oil capsule that avoids lubricant leakage. Thus this bearing is as quiet as a sleeve bearing but comes with a significantly higher service life.
