Radiator Aqua-Computer airplex radical 4/360 — Aluminium/Copper/Stainless steel, 400×140×73 mm

The Aqua-Computer airplex radical 4/360 is a 360-class radiator for PC liquid cooling systems, built from aluminium, copper and stainless steel. With compact external dimensions of 400 × 140 × 73 mm and a fin array sized for triple-fan configurations, this radiator is designed to provide efficient heat dissipation in high-performance water-cooling loops. The airplex radical construction avoids welding inside the cooling circuit so coolant only contacts seals, Delrin, copper and stainless steel, reducing risk of contamination and corrosion. Threaded nickel-plated brass inserts are fitted into the fan mounting holes to simplify fan alignment and allow safer screw clearance from the fins and tubes; inserts can be reversed for a nearly flat mounting surface when installing the radiator without fans.

Advantages

The radiator combines aluminium, copper and stainless steel to balance thermal performance, durability and corrosion resistance. Its no-weld manufacturing process eliminates welding residues inside the coolant path. Threaded inserts provide reliable fan alignment, deeper thread engagement and lower risk of damage from overly long screws. A stainless-steel frame with a dark gray chromated rear enhances structural stability and appearance while keeping overall dimensions compact relative to the fin area.

Suitable for

• High-performance custom PC water-cooling loops
• Triple-fan radiator mounts in full-tower or mid-tower cases
• Systems prioritising corrosion-resistant materials and clean coolant paths
• Builds requiring simple, repeatable fan alignment during installation

Key specifications

• Type: 360-class liquid cooling radiator (triple-fan)
• Materials in coolant path: copper and stainless steel; seals and Delrin components
• Frame material: stainless steel (rear chromated dark gray)
• Overall dimensions: 400 × 140 × 73 mm
• Manufacturing: no-weld construction to prevent internal welding residues
• Mounting features: threaded nickel-plated brass fan inserts with slide rails and locking notches

How to use

Mount the radiator in a compatible case position designed for a 360 mm (triple-fan) unit. Install the included threaded inserts into the slide rails on one side; additional inserts for the other side are available separately if needed. Attach fans to the radiator using the inserts so the fan holes align automatically with the threads, and use appropriately sized screws to avoid contact with fins and tubes. When installing the radiator without fans, reverse the inserts to create a near-flat surface between radiator and case. Integrate the radiator into your water loop following standard filling, leak-testing and drainage procedures for PC liquid cooling.

Recommendations

Use fans rated for static pressure to optimise airflow through the fin array. Select screw lengths that clear the radiator fins and tubes; the deeper insert threads reduce risk, but verify clearance visually. For long-term reliability, use corrosion-inhibited or mixed-metal compatible coolants and perform periodic maintenance and leak checks according to your cooling loop schedule.
