Liquid Cooling Combo Stealkey Customs SC ResPro 240 D5/DDC D-RGB — pump and reservoir unit

Stealkey Customs SC ResPro 240 D5/DDC D-RGB is a combined pump and reservoir unit designed for custom liquid cooling loops in desktop PCs. Tailored for 240 mm radiator setups, this module accepts either D5 or DDC pump form factors and integrates addressable RGB illumination to match system lighting. The unit consolidates pump performance and reservoir capacity into a compact housing to simplify loop layout, improve coolant circulation, and support sustained cooling for high-performance CPUs and GPUs.

Advantages

The integrated design reduces tubing clutter by combining reservoir and pump functions into a single module, which can simplify installation and improve internal airflow compared with separate components. Compatibility with both D5 and DDC pump types offers flexibility for different flow and pressure requirements. Built-in addressable RGB lighting provides customizable visual integration with other D-RGB components. The SC ResPro 240 D5/DDC D-RGB is intended to support reliable circulation in 240 mm radiator-based loops, helping maintain lower operating temperatures under sustained loads.

Suitable for

• Custom liquid cooling loops using a 240 mm radiator configuration
• Systems requiring compact pump-plus-reservoir integration to save space
• High-performance or overclocked gaming PCs needing sustained coolant circulation
• PC builds with addressable RGB ecosystems seeking coordinated lighting

Key specifications

• Form factor: combined reservoir and pump unit compatible with D5 or DDC pumps
• Intended radiator support: 240 mm loops
• Lighting: addressable RGB (D-RGB) integrated into the module
• Material: durable housing designed for coolant containment and mounting stability
• Connections: standard liquid cooling inlet and outlet ports suitable for common tubing sizes

How to use

Install the SC ResPro 240 unit in the case where it can be securely mounted and connected to the radiator, CPU/GPU blocks, and fill/drain points. Choose and install a compatible D5 or DDC pump into the module according to the pump manufacturer’s instructions, then connect inlet and outlet tubing to complete the loop. Prime the loop with appropriate coolant, check for leaks, and run the pump at low speed initially to ensure full circulation. Configure the D-RGB connection to the motherboard or controller to synchronize lighting if desired.

Usage recommendations

Use approved coolant and corrosion inhibitors, follow the pump manufacturer’s maintenance intervals, and verify mounting orientation and tubing routing to avoid air traps. Perform leak tests before powering the rest of the system and monitor pump operation and temperatures during initial operation and after any loop changes.
