Light Wings LX Fans
Performant, Yet Quiet Operation
Pure Loop 3 LX 360mm features 3 Light Wings LX 120mm PWM high-speed fans. They come with 16 LEDs that perfectly scatter across the fan blades and are key for the stunning visuals Pure Loop 3 LX 360mm offers. The fan’s 9 airflow-optimised fan blades not only reduce noise-generating turbulences but also ensure that Light Wings LX 120mm PWM high-speed provides the performance that is needed, even in demanding scenarios. A specially designed, funnel shaped air outlet is more than just the icing on the cake: it maximises the airflow over the fins. The fans also come with a “closed loop motor” function. This feature always keeps a steady fan speed, no matter the resistance – ideal for radiators.

Daisy Chain
No Need for a Fan Hub
If you want to connect more fans than your system has headers for, you are in for a problem. A water cooling system with pump and 3 fans on top of the case fans can hit the maximum available on a motherboard easily.
The daisy chain function of Pure Loop 3 LX 360mm allows all fans to be connected in series. providing fewer and shorter cables to help you achieve a cleaner look.

Impressively High Cooling Performance
Yes, It Can Run Crysis

Superior Pump Design
With State-of-the-Art Technology
A powerful PWM pump ensures the very high-performance of Pure Loop 3 LX 360mm and is whisper-quiet at the same time.
The 6-pole 3-phase motor provides a smooth and consequently silent operation, whether at high or low rpm.
