Radiator block Alphacool 14248 Brass Copper Steel Black 124x278x30mm

The Alphacool 14248 radiator block is a full-copper-design heat exchanger for watercooling systems, finished in black and sized 124 × 278 × 30 mm. It combines brass, copper and steel components to provide effective heat dissipation in PC cooling loops. The radiator is compatible with 120/140/180 mm fan mounting standards and uses standard M3 threads for fan and bracket installation.

Advantages

This NexXxoS series radiator features copper channel heads, fins and channels to improve thermal conductivity compared with radiators that only use copper for limited parts. Split channel heads and a flat end chamber support a high flow rate and reduce overall length for more flexible installation. The model includes inner protective edges to prevent screw damage to the fins and has 1/4" ventilation/fill threads on applicable variants to simplify bleeding and vertical installation. Fin spacing is chosen to allow good performance with slow to medium-speed fans, keeping acoustic levels low while maintaining cooling efficiency.

Suitable for

• Custom PC watercooling loops
• High-performance desktop systems requiring efficient heat dissipation
• Installations where compact radiator length is necessary

How to use

Mount the radiator in your case or external mounting position using the standard M3 threaded holes and compatible fan screws. Connect inlet and outlet ports to your loop using suitable fittings; the channel heads provide multiple attachment positions to reduce the need for angled fittings and to increase flow. If present on your variant, use the 1/4" vent/fill port to bleed air from the system during filling and to assist vertical mounting. Verify screw depth when installing to avoid contact with fins, though the inner protective edge provides additional protection.

Usage recommendations

For balanced cooling and low noise, pair the radiator with slow-to-medium-speed fans and ensure a high-flow pump to take advantage of the split-channel design. Use compatible 1/4" fittings for filling and bleeding where available, and allow sufficient clearance for fittings and tubing when planning installation.
