All-in-one liquid cooler Fractal Design Celsius+ S28 Prisma

The Fractal Design Celsius+ S28 Prisma is an all-in-one liquid cooler designed for CPU cooling in desktop systems. It features an ARGB-accented pump face, a redesigned water block, pre-applied thermal paste and an on-radiator PWM fan hub with ARGB support to simplify installation and cable management. The cooler is available in black and white and supports a wide range of Intel and AMD sockets.

Advantages

Intelligent auto mode dynamically adjusts pump and fan speeds for quieter operation, while a switchable PWM mode on the pump face allows full manual control. The ARGB-enabled PWM hub centralizes fan and ARGB connections on the radiator for a tidier build. Pre-applied thermal paste removes the need for separate application during mounting. Broad compatibility with current ARGB ecosystems (Asus AURA, Gigabyte Fusion, MSI Mystic Light, Razer Chroma, ASRock Polychrome) enables coordinated lighting effects.

Suitable for

• Compact and mid-tower desktop builds requiring liquid CPU cooling
• Systems where cable management and neat installation are priorities
• Users who want ARGB lighting synchronized with motherboard software

How to use

Mount the radiator in a suitable position inside your chassis and attach the pump/block to the CPU socket following the included mounting hardware and instructions for your specific Intel or AMD socket. Connect the pump and fans to the on-radiator PWM hub and link the hub to the motherboard for power, PWM control and ARGB signalling. Use the pump face switch to select auto mode for automatic fan/pump adjustment or PWM mode for manual control through the motherboard or a fan controller.

Recommendations

Install the cooler on a powered-off system, ensure the pre-applied thermal paste makes full contact with the CPU, route fan and ARGB cables through the braided tube sleeves for tidier cable management, and verify compatibility with your motherboard ARGB software if synchronized lighting is required.
