240mm Liquid Cooling Radiator Alphacool NexXxoS HPE‑30 — white

The Alphacool NexXxoS HPE‑30 240mm — white is a slim liquid cooling radiator designed for custom PC water cooling loops. Its 240mm length accommodates two 120 mm fans and provides a compact heat exchanger for CPU or GPU cooling in small-form-factor and mid-tower systems. The white finish supports a clean visual aesthetic while the low-profile design helps fit into constrained case layouts where space is limited.

Advantages

The slim construction reduces overall thickness compared with standard radiators, making it suitable for builds with limited clearance. Compatibility with two 120 mm fans allows flexible fan selection for silent or high-airflow configurations. As a component intended for custom loops, the radiator offers effective heat dissipation for processors and graphics cards when paired with appropriate pumps, blocks, and coolant. The white color integrates with light-themed builds and helps maintain a uniform appearance.

Suitable for

• Compact and small-form-factor PC builds where radiator thickness is a constraint
• Mid-tower systems requiring a 240 mm radiator for CPU or GPU cooling
• Custom water-cooling loops combining slim radiators with 120 mm fans
• White or light-themed builds seeking a coordinated component appearance

Key specifications

• Form factor: 240 mm radiator designed for two 120 mm fans
• Color: white finish
• Profile: slim / low-profile radiator construction
• Application: liquid cooling for CPU and GPU in custom loops

How to use

Install the radiator in a suitable position inside the case where a 240 mm radiator fits and where fan airflow is unobstructed. Mount two 120 mm fans on the radiator according to preferred push, pull, or push–pull configurations and secure with appropriate screws. Connect the radiator to the custom loop using compatible fittings and tubing, ensuring proper orientation of inlet and outlet ports and secure, leak-free connections. Fill, bleed, and cycle the loop following standard liquid cooling procedures and monitor temperatures and leak points during initial operation.

Recommendations

Use fans with compatible mounting depth to match the slim radiator profile and choose fan speeds that balance noise and cooling performance. Pair the radiator with components (pump, reservoir, blocks) sized for the intended thermal load and use coolant and corrosion inhibitors recommended for PC water-cooling loops. Regularly inspect fittings and tubing for tightness and check for dust buildup on fins to maintain optimal thermal performance.
