The Thermaltake Pacific C240 (CL-W227-CU00BL-A) is a premium 240mm custom loop water cooling radiator designed for PC enthusiasts building in space-constrained mid-tower or mini-ITX chassis. Part of Thermaltake’s renowned C-Series, it combines a highly efficient flat-tube copper core with a remarkably slim 27.5mm profile, providing builders with high-end thermal headroom without interfering with oversized motherboards or massive graphics cards.
• Key Features
Ultra-Slim 27.5mm Form Factor: Designed for maximum compatibility, the slim profile easily clears tight spaces in compact cases while still offering robust cooling surface area.
Premium Copper & Brass Construction: Features high-grade copper flat tubes and fins paired with brass tanks, ensuring maximum thermal conductivity and corrosion resistance.
Optimized High-Density Fins (17 FPI): The 17 Fins-Per-Inch array is precision-engineered to accommodate high air volume and high static pressure fans, ripping heat away from the loop rapidly.
Stainless Steel Side Panels: Built with rigid stainless steel side panels that guarantee durability, structural integrity, and a premium aesthetic that resists bending during installation.
Universal Dual 120mm Fan Support: Natively supports any standard 120mm cooling fans (2x 120mm), allowing you to customize your loop with RGB or industrial-grade static pressure fans.
High-Quality Manufacturing Process: The radiator is baked through a state-of-the-art soldering line, ensuring impurities are kept out of the loop and joints remain leak-proof under pressure.
• Performance / Technology
Efficient heat dissipation relies on pulling heat away from the coolant as fast as possible. The Pacific C240 achieves this via its optimized internal copper micro-channel flat tubes. By expanding the fluid contact area inside the radiator and pairing it with a high-density fin structure, this radiator effortlessly handles the heavy thermal loads generated by modern multi-core processors and flagship GPUs, preventing thermal throttling during intensive gaming or 3D rendering.
• Design & Ergonomics
Coated in a sleek, anti-corrosive matte black finish, the Pacific C240 blends seamlessly into any stealth or RGB-heavy build. Standard G1/4" inlet and outlet threads are perfectly machined into the brass tanks, ensuring 100% compatibility with any brand of rigid hard-tube or soft-tube fittings.
• Compatibility / Use Cases
The Thermaltake Pacific C240 utilizes universal G1/4" threads and standard 120mm fan spacing, making it universally compatible with EKWB, Corsair, Bitspower, and Alphacool custom loop components. It is the ideal radiator for Mini-ITX small form factor (SFF) builds, dual-radiator mid-tower setups, and custom gaming PCs where a thick radiator would block the motherboard components.
• Why This Product Stands Out
Many budget slim radiators cut costs by mixing aluminum cores with copper loop components, leading to catastrophic galvanic corrosion. The Thermaltake Pacific C240 uses a pure copper and brass internal structure, ensuring your custom loop remains clean, safe, and highly efficient for years, while its 27.5mm thickness makes installation completely hassle-free.
