Vloeistofkoelingsset Alphacool T38 12 cm zwart 2500 RPM hydraulisch

The Alphacool Core Ocean AiO is an all-in-one CPU liquid cooler designed for users seeking a cost-effective entry into performance-oriented water cooling. Unlike Alphacool's expandable Eisbaer series, the Core Ocean is a closed AiO solution not intended for adding additional radiators, GPU coolers, or expansion tanks. The unit supports common mainstream AMD and Intel sockets and is engineered for long service life with low maintenance.

Advantages

The aluminium T38 radiator includes additional cooling channels that increase cooling capacity without restricting water flow, while its 38 mm height allows installation in compact cases with single-fan mounting. The included PWM fan is controllable from 0–2500 rpm and delivers high airflow and static pressure suitable for radiator use. The combined pump and copper base feature fine cooling fins and a nozzle plate for even, optimised heat transfer across the cooler base. Integrated 5V addressable RGB LEDs in the pump provide digital illumination, and a high-conductivity thermal paste (7.5 W/mK) is supplied.

Key specifications

• Radiator: T38 aluminium, height 38 mm, single-fan configuration
• Fan: 4-pin PWM, 0–2500 rpm, airflow 62.8 CFM, static pressure 2.13 mm/H2O, 40 cm cable
• Pump: PWM controllable, speed range approx. 2500–3500 rpm (±10%), connected via 4-pin fan connector
• Compatibility: Common mainstream AMD and Intel CPU sockets
• Hoses: 40 cm FEP, sleeved, rotatable 360° fixed connections (non-replaceable)
• Lighting: 12 × 5V digitally addressable aRGB LEDs, JST 3-pin connector, requires digital RGB controller or compatible motherboard
• Thermal paste: included, thermal conductivity 7.5 W/mK

How to use

Install the Core Ocean AiO according to the motherboard socket mounting instructions: mount the radiator with the fan in the chosen case location, apply the supplied thermal paste to the CPU heatspreader, and attach the cooler base to the CPU socket following the included mounting hardware steps. Connect the fan and pump to the motherboard or an external PWM controller using the provided 4-pin connectors. For RGB lighting, connect the pump's JST 3-pin aRGB plug to a compatible digital RGB header or controller and configure lighting through the motherboard software or controller.

Recommendations

For reliable operation, ensure adequate case airflow and secure routing of the 40 cm hoses to avoid strain on the fixed 360° connections. Use a compatible 5V digital RGB header or controller to control lighting. The Core Ocean is not expandable — do not attempt to add radiators or external cooling components. Periodically inspect fittings and clean dust from the radiator and fan to maintain optimal cooling performance.
