## Long description

The DeepCool LS720S Zero Dark is an all-in-one liquid cooler with a 360 mm radiator and three 120 mm PWM fans designed for silent, efficient CPU cooling. The Zero Dark edition features an all-black aesthetic with minimal lighting, an aluminum pump housing with a rotatable cover, and DeepCool's 4th generation pump architecture including optimized microchannels, a powerful three-phase motor (up to 3100 RPM) and a solid copper coldplate. The unit includes anti-leak technology and mounting hardware compatible with current mainstream Intel and AMD sockets.
Advantages
The LS720S Zero Dark combines high cooling capacity with a low-profile, light-minimal design suitable for professional or stealth builds. Its 4th generation pump improves coolant flow and thermal transfer, while the included optimized PWM 120 mm fans use Hydro Dynamic Bearings for quieter operation and extended lifespan. Anti-leak technology helps prolong useful life and reduces the risk of leakage. Aluminum pump housing adds rigidity and a clean finish.
Suitable for
High-performance desktop CPUs requiring powerful cooling
Silent or low-light PC builds where minimal RGB is preferred
Workstations and professional rigs focused on component aesthetics

How to use
Install the radiator and three PWM fans into the case mounting points compatible with a 360 mm radiator. Mount the pump unit on the CPU following the included mounting hardware instructions for your socket type (Intel or AMD), ensuring the coldplate makes full contact with the CPU heat spreader. Connect the pump power and fan PWM connectors to the appropriate motherboard headers or a fan controller. After installation, verify pump and fan operation in BIOS or with monitoring software and ensure secure tubing routing to avoid kinks.
Usage recommendations
For optimal results, apply a thin, even layer of thermal paste, keep airflow unobstructed around the radiator, and periodically check fan and pump operation. Ensure case compatibility with a 360 mm radiator and follow the manufacturer’s installation guide for socket-specific torque and mounting sequence.
