Product information

Description

SilentiumPC Poseidon Ultra 240 ARGB White is an all-in-one liquid CPU cooler with a 240 mm radiator and two 120 mm Vortent fans. Designed for compact and full-size PC builds, it combines a reduced-thickness copper cold plate, a water block engineered to boost coolant flow, and ARGB lighting controllable via compatible motherboard software. The cooler supports a wide range of Intel and AMD sockets and targets modern processors that require efficient heat dissipation in constrained or performance-oriented systems.

Advantages

The Poseidon Ultra 240 offers a balance of cooling performance and low acoustic output through a fan frame that creates a vortex effect to concentrate airflow and increase static pressure. The water block increases coolant flow and expands fin contact area while the reduced copper plate thickness improves conduction. Integrated corner dampeners and a stabilized grooved impeller reduce vibration and turbulence, delivering effective thermal transfer with minimized noise. ARGB lighting is supported and can be synchronized with motherboard software for consolidated control.

Suitable for

  • Cooling mainstream and high-efficiency desktop CPUs in compact or mid/full-tower cases
  • Systems where low noise and higher static pressure fans are preferred for radiator performance
  • Builds that require ARGB lighting synchronized with motherboard control software

  • PWM support for fan speed control
  • Water block: reduced-thickness copper plate for improved conduction and increased fin contact area
  • Cooling improvements: increased coolant flow and expanded fin surface for higher heat transfer efficiency
  • Dimensions (fan): 120 x 120 x 25 mm
  • Colour: White
  • Product weight: 0.773 kg
  • Compatible sockets: AMD AM5/AM4/AM3/AM2/FM1/FM2 and Intel LGA 1700/1200/115x series

How to use

Install the Poseidon Ultra 240 by mounting the radiator and its two fans in the chosen case location (front, top or rear depending on case layout and airflow preference) using the included hardware. Secure the water block to the CPU socket following the socket-specific mounting brackets and torque guidance provided by the manufacturer. Connect the pump and fans to the motherboard headers: attach the pump power connector to the appropriate pump or CPU_FAN header and plug the fans into PWM fan headers to allow automatic speed regulation. Connect the ARGB cable(s) to a compatible ARGB header or controller and enable synchronization in the motherboard lighting software.

Usage recommendations

Ensure adequate case airflow by planning intake and exhaust fan placement to complement the radiator location; regular dust filtration and periodic cleaning of the radiator fins and fan blades will help maintain cooling efficiency. Use motherboard fan curves or dedicated fan control software to balance noise and performance, and confirm compatibility with your case dimensions and the target CPU socket before installation.
