Radiator Aqua-Computer airplex radical 4/480 — Aluminium/Copper/Stainless steel, 520×140×73 mm

Aqua-Computer airplex radical 4/480 is a high-capacity liquid-cooling radiator for PC water-cooling loops, built from aluminium, copper and stainless steel. With overall dimensions of 520 × 140 × 73 mm, the radiator provides dense fin and channel arrays for effective heat dissipation in desktops and workstations. The airplex radical design follows a no-weld production method so the coolant contacts only seals, Delrin, copper and stainless steel, reducing the risk of internal residues and preserving thermal performance. Threaded nickel-plated brass inserts are integrated into the mounting system to simplify fan alignment and reduce the risk of damage from overly long screws; inserts can be inverted for a flush installation without fans.

Advantages

The radiator combines aluminium fins, copper channels and a stainless steel frame to balance thermal conductivity, structural rigidity and corrosion resistance. No welding is used during production, eliminating welding residues inside the coolant path. Threaded nickel-plated brass inserts that protrude into fan mounting holes ensure reliable and fast fan alignment, deeper threads and safer screw positioning away from tubes and fins. Slide rails on both sides enable flexible insert placement and locked positioning. The compact external dimensions relative to fin area deliver high cooling capacity while simplifying installation in constrained enclosures.

Suitable for

• High-performance desktop and workstation custom water-cooling loops
• Multi-fan radiator configurations requiring secure and aligned fan mounting
• Systems where reduced internal contamination and material compatibility are important
• Builds that require a large fin area in a compact external footprint

Key specifications

• Materials: aluminium fins, copper internal channels, stainless steel frame
• External dimensions: 520 × 140 × 73 mm
• Design: multi-fin, multi-channel radiator for liquid cooling
• Mounting: threaded nickel-plated brass inserts with slide rails and locking notches
• Finish: chromated dark gray rear of stainless steel frame

How to use

Install the radiator in the PC chassis where airflow is available and compatible with radiator dimensions. Mount fans using the supplied threaded inserts on the side delivered with the product; align the fans so screw threads engage the inserts and tighten screws to manufacturer-recommended torque to avoid over-tightening. If installing without fans, invert the inserts to create a near-flat mounting surface. Connect radiator ports to the loop using appropriate fittings and tubing, ensure correct flow direction and fill the loop with compatible coolant. Perform a leak test before powering system components.

Recommendations

Use corrosion-resistant coolant compatible with copper and aluminium components and avoid mixing dissimilar metals in the loop where possible. Use screws of the correct length and thread type; the supplied inserts allow safer screw placement away from fins and tubes. Periodically inspect the radiator and fittings for leaks and clean external fin surfaces to maintain optimal airflow and heat transfer.
