All-in-one liquid cooler Sharkoon S90 RGB

The Sharkoon S90 RGB all-in-one liquid cooler is a compact CPU cooling solution designed for a wide range of desktop builds. It combines a 120 mm fan with a closed-loop radiator to provide steady thermal performance while maintaining a modern black appearance. The fan operates between 600 and 2000 RPM, producing an airflow rating of 131.93 m³/h and a maximum static pressure of 2.9 mmH2O to support heat dissipation from the CPU block and radiator fins.

Advantages

The S90 RGB integrates a pre-filled, maintenance-free loop with a reliable pump and a 120 mm fan to deliver consistent cooling without requiring user refills. Its rotational speed range allows for a balance between noise levels and thermal output. The compact radiator and black finish make it suitable for small and mid-tower cases while the RGB accent lighting provides basic visual integration with RGB-capable systems.

Suitable for

• Compact and mid-tower gaming PCs that require efficient single-fan liquid cooling
• Workstation systems with moderate to high CPU loads seeking improved thermal control
• Builds where a black, low-profile radiator and 120 mm fan are preferred for space or aesthetic reasons

How to use

Install the radiator and 120 mm fan into an appropriate mounting position in your case, following the chassis manufacturer’s recommendations for airflow direction. Secure the pump/block assembly to the CPU socket using the included mounting hardware for your specific processor type. Connect the fan and pump power connectors to the motherboard or fan controller, and configure fan curves in BIOS or software to achieve the desired balance of cooling performance and noise. No user filling or coolant maintenance is required for the sealed loop.

Recommendations

For optimal results, ensure good case ventilation with at least one intake and one exhaust fan to complement the S90 RGB. Regularly check for dust buildup on the radiator fins and fan blades and clean gently to maintain airflow and cooling efficiency.
