Thermaltake Pacific C240 Radiator

The Thermaltake Pacific C240 Radiator is a high-performance companion for custom water-cooling builds, delivering exceptional thermal efficiency in a slim 240mm footprint. Crafted with a copper flat-tube core, dense copper fins, and brass end tanks, it blends industrial-grade materials with precision engineering to provide reliable cooling under demanding workloads. Whether you're pushing a high overclock in a gaming rig or rendering complex scenes, the Pacific C240 is designed to maintain whisper-quiet operation by enabling you to run fans at lower speeds without sacrificing temperatures. Its rugged construction and thoughtful design make it a standout choice for enthusiasts who demand both performance and durability from their liquid cooling system.

• Exceptional cooling efficiency — The Pacific C240 pairs a copper flat-tube core with high-density copper fins to maximize heat transfer from coolant to ambient air. Copper’s superior thermal conductivity, combined with optimized fin density, translates to lower coolant temperatures, more stable loads, and a broader margin for overclocking. In real-world conditions, this radiator tends to outperform many all-aluminum rivals of similar size by delivering quicker heat removal and reduced thermal throttling. The result is cooler CPU and GPU temperatures, enabling sustained performance during long gaming sessions or crunch-heavy workloads, with fans able to operate at quieter speeds for a more pleasant overall system noise profile.
• Slim 240mm footprint for flexible builds — Designed to fit standard 240mm radiator mounts while maintaining a compact profile, the Pacific C240 is ideal for cases with tighter clearance or multi-radiator configurations. The slim form factor helps preserve memory clearance, enables easier cable routing, and fits in cases that prioritize airflow without sacrificing radiator capacity. This balance of size and performance makes it a preferred option for mid- to high-end builds where space is at a premium but cooling needs remain uncompromised.
• Durable brass end tanks and copper core — The brass end tanks and copper core are built for long-term reliability in demanding cooling loops. Brass tanks provide robust, corrosion-resistant ends that maintain a tight seal around the copper core, helping prevent leaks even under varying thermal loads. Meanwhile, the copper flat-tube design ensures consistent coolant passage and minimal flow restriction, supporting stable flow rates through pumps and blocks. This combination of materials is a hallmark of Thermaltake’s Pacific line, delivering both durability and performance that enthusiasts trust for years of service.
• Premium compatibility and mounting versatility — The Pacific C240 is engineered for easy integration into custom loops. It supports standard 120mm fan spacing and mounting patterns, making it straightforward to pair with a broad range of fans and case configurations. The radiator’s design accommodates various routing options, whether you prefer a push, pull, or push-pull setup. With standard G1/4" fittings in mind, it works seamlessly with widely used tubing, barbs, and fittings, enabling you to tailor your loop’s layout to your exact aesthetic and flow requirements while preserving optimal coolant flow and minimal turbulence.
• Optimized for quiet, stable operation — Cooling efficiency translates into quieter operation, especially when paired with high-quality fans and properly tuned fan curves. The Pacific C240’s core geometry and low-restriction design reduce the need for aggressive cooling fan speeds, allowing your system to maintain comfortable noise levels even when under heavy load. This makes it an attractive option for living room PCs, quiet workstations, or streaming rigs where a balance of performance and acoustic comfort is essential. Additionally, the robust construction minimizes the risk of resonance and vibration, helping maintain a stable, quiet cooling environment over time.

how to install Thermaltake Pacific C240 Radiator

To install the Pacific C240, follow these general steps. Ensure you power off and unplug your system before starting, and perform a leak test after assembly to prevent any coolant leaks from damaging components.

• Mount the radiator in the case’s 240mm location, aligning with the case’s fan brackets. Use the included screws or compatible hardware to secure the radiator firmly and minimize vibrations.
• Attach two 120mm fans to the radiator using the appropriate screws. Choose push, pull, or a combination based on your case airflow strategy and acoustic preferences.
• Route tubing from the radiator to your water block, pump, and reservoir in a clean loop order. Use standard fittings (G1/4") with clamps or compression fittings as required, ensuring tight seals and avoiding sharp bends that could restrict flow.
• Fill the loop with coolant and bleed air from the system. Re-check all fittings for leaks and tighten as necessary after the initial bleed.
• Power on the pump and run a controlled leak test for several hours. Monitor temperatures and inspect joints for any signs of leakage, addressing any issues before regular operation.
