Who it fits

Key specs explained for you

Radiator Size: 480mm

This length provides a large surface area for heat exchange. You gain more cooling capacity compared to smaller 120mm or 240mm units. This spec suits cases with ample space for long radiators. It helps maintain lower loop temperatures under heavy loads. Check your case dimensions to ensure this 480mm length fits before purchasing.

Material: Copper

Copper offers high thermal conductivity for efficient heat transfer. You get better cooling performance compared to aluminum radiators of the same size. This material is dense and durable for long-term use. It is ideal for custom loops where maximum heat dissipation matters. Compare this against aluminum options if weight or budget is your primary constraint.

Weight: 15.9 ounces

This weight indicates a solid, dense construction typical of copper. You should ensure your case mounts can support this mass without sagging. It suggests robust internal fins and tubes rather than hollow or thin materials. This spec helps you evaluate structural integrity. Heavier radiators often correlate with better heat retention and dissipation capabilities.

G1/4 thread

This standard port size allows easy connection to common fittings. You benefit from widespread compatibility with various tubing and connectors. It simplifies installation and removal for maintenance or loop changes. This spec is crucial for custom builders who mix components. Verify your fittings match this thread standard to avoid leaks or compatibility issues.

Design and Build Quality

According to the listing, this radiator is constructed from high-grade copper. Copper offers superior thermal conductivity compared to aluminum, which means it transfers heat from the coolant to the fins more efficiently. This material choice supports sustained cooling performance in custom loops. The unit weighs 15.9 ounces. This weight is manageable for mounting but requires sturdy case brackets to support the load without sagging. The compact and portable design suggests it fits well in standard ATX or E-ATX cases that accommodate long radiators.

The listing notes exquisite workmanship with no weak welding or glue marks. This implies a durable construction that can withstand the pressure of continuous liquid circulation. The presence of G1/4 threaded ports allows for easy installation and removal of fittings. This standard size ensures compatibility with most common tubing and connectors in the DIY liquid cooling market. You do not need special tools to attach your hardware.

FOSA markets this unit for various high-power cooling needs, including computer water cooling, beauty equipment, and large LEDs. The low-noise design is optimized for quieter operation. This makes it suitable for users who prioritize acoustic performance alongside thermal efficiency. The 480mm size provides a large surface area for heat exchange. You gain more cooling capacity than with smaller 120mm or 240mm units. This spec suits cases with ample space for long radiators. It helps maintain lower loop temperatures under heavy loads.

Setup And Everyday Use Guide

Installing this FOSA radiator involves connecting standard G1/4 threaded fittings to the ports. The listing notes that these ports allow for easy installation and removal, which simplifies loop assembly and maintenance. You should ensure your tubing and fittings match this standard thread size for a secure connection. The unit weighs 15.9 ounces, making it manageable during placement within your case. Its 480mm length requires a chassis with sufficient space to accommodate the long form factor. You must verify that your case supports this radiator size before purchase. The copper construction suggests efficient heat transfer, which supports stable temperatures during operation. FOSA describes the workmanship as delicate and compact, with no weak welding or glue marks visible. This implies a robust build that can withstand the pressure of a custom loop. The low noise design is achieved through specific optimization, aiming to provide better cooling performance without excessive fan speed. This feature is relevant for users who prioritize quiet operation alongside thermal efficiency. The radiator is suitable for various high-power cooling needs, including computer water cooling and large LED equipment. Daily use relies on the integrity of your loop’s coolant and pump. The copper material is noted for long-term use, indicating durability under standard liquid cooling conditions. You benefit from the high-grade copper’s thermal properties, which help dissipate heat effectively. The G1/4 ports ensure compatibility with a wide range of common fittings, reducing the need for specialized adapters. This setup is ideal for builders who value straightforward connections and reliable thermal performance in a compact, portable package.

Before You Buy This Radiator

Before you buy this 480mm copper radiator, verify your case has enough space. A 480mm length is long, so you need ample clearance for fans and tubing. You must also check port compatibility. The listing specifies G1/4 threaded ports, which is standard, but confirm your fittings match this size to avoid leaks. Since this unit is just a heat exchanger, you will need separate pumps, reservoirs, and tubing to complete your custom loop. Copper offers excellent thermal conductivity, but it requires careful maintenance to prevent corrosion if you use non-premixed coolants. Ensure your coolant choice is compatible with copper components. This radiator fits users who prioritize high heat dissipation in spacious builds. It suits those building extensive custom loops rather than those seeking plug-and-play AIO solutions. If you lack space or prefer simplicity, consider smaller radiators or all-in-one units instead. Proper planning ensures your cooling system runs efficiently and quietly over time.

Check before you buy

• Verify your case fits the 480mm length with fan clearance.
• Confirm your fittings match the G1/4 threaded ports.
• Ensure your coolant is safe for copper components.
• Check that you have a pump and reservoir ready.
