Thermaltake Pacific CL360 64mm Thick Copper Radiator - High Cooling

In this review the Thermaltake Pacific CL360 64mm copper radiator is examined for builders who need high thermal capacity in custom liquid cooling loops. It is aimed at enthusiasts and overclockers who want strong heat dissipation from a dense copper fin array and triple-row flat tubes; the single biggest reason to buy is its focus on raw thermal performance thanks to a 64mm thickness, brass tank and high-density copper fins optimized for pulling heat away from circulating coolant.

Key Features

• Triple-row flat tube design: the three-row layout increases coolant contact area so heat is transferred efficiently for demanding CPU and GPU loops.
• High-density copper fin design: 14 fins per inch and dense copper material improve heat conduction and make the radiator effective at both low and high airflow.
• Brass tank construction: a brass tank provides better corrosion resistance and thermal capacity compared with common alternatives.
• Stainless steel frame: side panels add rigidity and reduce weight while protecting the core during installation and long-term use.
• G1/4" threaded ports: standard threaded connections make installation straightforward and help ensure leak-resistant fittings when mounted correctly.
• Controlled atmosphere soldering: the manufacturing process promotes strong joints between tubes and fins for improved thermal transfer and durability.

Who It's For

The Pacific CL360 suits PC builders who prioritize maximum heat dissipation in triple 120mm fan mounts and are comfortable accommodating a thicker radiator in their case. It is particularly appropriate for systems running high TDP CPUs or multi-GPU loops where continuous, efficient coolant heat extraction is required.

It is less suitable for compact cases or users who need the slightest clearance margins, because the 64mm thickness can conflict with fan or component spacing; users seeking a shallower, ultra-thin radiator should look elsewhere.

Pros & Cons

Pros

• High thermal capacity from the triple-row copper tubes and high-density fins, delivering strong heat transfer under load.
• Durable construction with a brass tank and stainless steel side panels for long-term reliability and reduced weight compared with some full-steel designs.
• Standard G1/4" threads and quality soldering improve ease of installation and thermal contact between components.
• Optimized for both low and high airflow, so performance remains solid with high-static pressure fans.

Cons

• At 64mm thick, the radiator can present fitment challenges in many cases and with some fan configurations.
• Some users report mixed experiences with fin condition and occasional leakage issues, so careful inspection and proper mounting are advised.

Frequently Asked Questions

Will this radiator fit standard triple 120mm mounts?
Yes, it is designed for triple 120mm fan mounts, but verify your case clearance for the 64mm thickness plus fan depth.

Are the threaded ports compatible with common fittings?
Yes, the integrated G1/4" threads work with standard water cooling fittings used in most custom loops.

Is the radiator prone to leakage?
Most users report no leakage, but some have had issues; inspect joints and fittings carefully and follow proper assembly to minimize risk.
