## Summary description

THERMALTAKE R540S is an aluminium radiator block for liquid cooling systems. Finished in black, it measures 179 × 615.3 × 36 mm and weighs 1.14 kg. Designed to transfer heat from coolant to air, it fits custom loop and PC cooling setups where a compact, long-format aluminium radiator is required for efficient thermal dissipation.

## Long 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.
