Product information

Description

THERMALTAKE R540S is an aluminium radiator block for custom liquid cooling loops, finished in black and sized at 179 × 615.3 × 36 mm. Weighing 1.14 kg, this slim-format radiator is engineered to transfer heat from coolant to airflow efficiently in compact and long-format PC cooling setups. The R540S uses a 13-flat-tube configuration and a high-density fin layout to improve heat exchange and is manufactured using high-temperature brazing for strong joints between tubes and fins. Integrated threaded ports and a slim profile make it suitable for a variety of custom loop layouts where reliable thermal dissipation and space-conscious installation are required.

Advantages

The aluminium construction provides a balance of weight and thermal conductivity while anti-corrosion zinc alloy treatment reduces electrochemical degradation over time. A high fin-per-inch design and slim form factor enable effective cooling with higher fan speeds and tight mounting spaces. The brazing manufacturing process produces robust tube-to-fin connections that enhance thermal transfer and long-term structural integrity. Integrated G1/4"-compatible threaded ports facilitate leak-resistant fittings and straightforward integration into existing custom loops.

Suitable for

  • Custom PC liquid cooling loops where a long, slim radiator is needed
  • Systems requiring a 540mm-equivalent cooling solution in a compact footprint
  • Multi-radiator configurations to spread thermal load across components
  • Enthusiast builds prioritizing efficient heat dissipation and modular installation

Key specifications

  • Material: Aluminium with zinc-alloy anti-corrosion treatment
  • Colour: Black finish
  • Dimensions: 179 × 615.3 × 36 mm
  • Weight: 1.14 kg
  • Tube design: 13-set flat tube configuration
  • Fin density: 13 FPI (fins per inch)
  • Manufacturing: High-temperature brazing for tube-to-fin joints
  • Ports: Standard threaded ports compatible with G1/4" fittings

How to use

Install the radiator into your case or external mounting location using the standard screw holes and recommended fan mounting positions. Connect fittings and tubing that are compatible with G1/4" threads and ensure all connections are tightened to manufacturer torque recommendations to avoid leaks. Mount fans to the radiator according to desired push, pull, or push-pull configuration to achieve the required airflow and cooling performance. When integrating into a custom loop, prime and pressure-test the system before powering the PC to confirm leak-free operation and proper coolant flow through the radiator.

Usage recommendations

Use corrosion-resistant coolant compatible with aluminium radiators, and avoid mixing dissimilar metals in the loop unless appropriate corrosion inhibitors or dielectric solutions are used. Regularly inspect fittings and tubing for wear, and perform a periodic coolant replacement schedule (manufacturer-recommended intervals) to maintain optimal thermal performance and prevent buildup. Ensure adequate case airflow to complement the radiator’s fin density and consider higher static-pressure fans for dense fin configurations.

Reasons to buy

Optimized Heat Dispatching for Reliable Cooling

THERMALTAKE R540S radiator block is engineered for demanding enthusiasts and custom liquid-cooling builds. Its brazed fin-and-tube construction creates a continuous thermal path that efficiently transfers heat from coolant to fins, producing consistent heat dissipation (typical fin temperatures around 32–35℃) and improving component reliability under sustained loads.

High-Density Fin Design for Improved Airflow Performance

The radiator features an optimized fin-per-inch (FPI) arrangement that accepts high air pressure and benefits notably from increased fan speed. This high-density fin layout boosts cooling capacity in compact, long-format configurations, making it ideal for systems that require strong airflow-driven heat removal.

Premium Brazing Process for Structural Strength and Thermal Conductivity

Manufactured using a controlled-atmosphere brazing process at approximately 1022℉ (550℃), the R540S achieves clean, strong joints between tubes and fins. This high-temperature brazing minimizes impurities and fusing imperfections so thermal transfer between materials is maximized for efficient heat evacuation.

Flexible Sizing and Modular Integration

The R540S is available in multiple sizes to support custom configurations and aesthetic builds. Its compact long-format dimensions (179 × 615.3 × 36 mm) and black finish make it easy to allocate radiators to specific components or install externally modular upgrades for a polished liquid-cooling loop.
