Thermaltake launches 3 new DIY hard tube water cooling kit on November 2nd 2026, providing a unified pump system to DIY custom liquid cooling. These new kits make DIY easier and more streamlined through ready-to-use package, which includes the necessary parts for a water cooling setup (Pacific PR22-D5 reservoir & pump combo, V-Tubler PETG Hard Tube) so users can avoid the hassle of hunting down parts and focus on the system setup straight away. These kits are perfect for those who wants to achieve reliable temperature management without the hassle of checking if the parts are compatible.
Thermaltake expands its Pacific series with three new DIY hard tube water cooling kits featuring the Pacific PR22-D5 pump and reservoir combo, V-Tubler PETG hard tubes, and varying radiator thicknesses to suit different case sizes and cooling requirements.
Thermaltake's new kits are Pacific Gaming RL360 D5, Pacific R360 D5 and Pacific R240 D5. All the kits share the high flow rate D5 pump & reservoir block, which guarantees a steady flow of liquid. The flagship Pacific Gaming RL360 D5 (model CL-W199-CU00SW-A) features a thick 64mm radiator and nickel-plated copper base water block for better thermal efficiency.
Spec comparison
| Spec | Pacific Gaming RL360 D5 | Pacific R360 D5 | Pacific R240 D5 |
|---|---|---|---|
| Radiator Size | 360mm | 360mm | 240mm |
| Radiator Thickness | 64mm | Slim (17FPI) | Slim (17FPI) |
| CPU Water Block | Pacific W1 (Nickel-plated) | Pacific W3 (Clear PMMA) | Pacific W3 (Clear PMMA) |
| Coolant Included | 1000ml C1000 Pure Clear | 1000ml C1000 Pure Clear | 1000ml C1000 Pure Clear |
For more customization, these kits have different technical specs to fit various case sizes and cooling requirements. Pacific Gaming RL360 D5 comes with a 360mm Pacific RL360 Radiator (14 fins/inch) and Pacific W1 CPU Water Blocks, also Riing Plus 12 RGB Radiator Fan (ARGB LED) for further customization. For more compact cases, Pacific R360 D5 and Pacific R240 D5 are designed with 17FPI slim radiator for greater flexibility.
Pacific R360 D5 comes with a 360mm Pacific R360 Radiator. Pacific R240 D5 comes with a 240mm Pacific R240 Radiator. Both of the slim variants use Pacific W3 CPU Water Block, which features copper base and clear PMMA cover.
To help users start using right away, the kits come with 1000ml Thermaltake C1000 Pure Clear Coolant. R360/R240 kit uses chrome-plated fittings that match the clear coolant/tubes.
Thermaltake has yet to announce the pricing and availability of the new cooling kits. Pricing and availability will be announced via official retail channels in the future. This announcement marks the expansion of Pacific Series.
Unified pump compatibility is the focus of this expansion. Further details on distribution timeline will be announced via official vendor information.
Does the 64mm thick radiator on the RL360 actually fit in standard mid-tower cases or is it just for full tower enclosures now?
The 64mm thickness is significantly thicker than the standard 25-30mm. It will likely block the rear fan intake in many mid-towers. You need to check your specific case clearance before buying the RL360. The R360 and R240 slim versions are safer for compact builds.
thick radiators are a pain to fit tbh 😬
I just want to know if the included 1000ml of coolant is enough for a dual loop setup. It feels like they always short change the fluid volume in these kits.
The unified pump system is the only smart move here. Proprietary fittings usually fail after two years. At least the D5 is a standard. We just need to hope the reservoir does not leak.
Will the nickel plated copper base on the W1 block cause galvanic corrosion if I mix it with aluminum parts in a custom loop?
Yes mixing copper and aluminum is a bad idea. The W1 block is nickel plated but the base is copper. You should use a dedicated aluminum water block or stick to all copper/nickel components. The coolant inhibitor helps but it is not a magic shield.
The 14FPI on the flagship radiator is inefficient for air cooling. 17FPI is the sweet spot for most fans. Thermaltake is pushing thickness over airflow performance here.
another expensive kit that costs more than a gpu 💀
I hope the software to control the Riing Plus fans does not include telemetry or forced cloud updates. Hardware should just work without phone apps.
