EMBRACE THE DARKNESS
There is something about premium systems with little to no lighting. The LS520S ZERO DARK is the perfect liquid solution for cooling higher end processors that emphasizes the actual components. RGB need not apply

BUILT STRONG!
Aluminum was chosen to provide a pristine appearance while also adding extra rigidity to the pump housing. The large pump cover is rotatable, and easy to adjust.

HIGHLY EFFICIENT FANS
Optimized PWM fans are included with the LS520S ZERO DARK and have been fine-tuned to provide excellent cooling performance with a whisper-quiet, long-life Hydro bearing. The LS520S ZERO DARK will include three of these specialized PWM fans.

SIMPLIFIED INSTALLATION
The included mounting hardware provides an easy installation process that ensures proper contact and equal pressure on both Intel and AMD platforms. Everything needed to mount the LS520S ZERO DARK to the latest mainstream CPUs is included in the box, so you are ready to go.
