Water block Corsair CT-9010011-WW Copper Nylon Black 400g

The CORSAIR XC5 RGB CPU water block (CT-9010011-WW) is a copper-and-nylon cooling component designed as the central element of a custom liquid-cooling loop. With a copper cold plate and a black nylon exterior, this 400 g water block provides efficient heat transfer from the CPU and integrates addressable RGB lighting for system illumination and synchronization with CORSAIR iCUE-compatible devices.

Advantages

The XC5 combines a copper cold plate with more than 60 high-efficiency micro-cooling fins to draw heat away from the processor, helping to lower operating temperatures and support higher clock speeds. Integrated RGB lighting uses 16 LEDs across eight zones for detailed lighting effects, and compatibility with CORSAIR iCUE software and an optional iCUE lighting controller enables synchronized customization across multiple CORSAIR RGB products.

Suitable for

• Custom liquid-cooling PC builds requiring a dedicated CPU water block
• Enthusiast and high-performance systems aiming for lower CPU temperatures and higher sustained clock speeds
• Systems where synchronized RGB lighting with other CORSAIR iCUE-compatible components is desired

How to use

Install the XC5 RGB as the CPU water block within a closed custom cooling loop following the motherboard and case manufacturer guidelines. Mount the block onto the CPU with appropriate thermal interface material and secure the fittings to the loop tubing. Connect the RGB cable to a compatible CORSAIR iCUE controller or header to enable lighting control via CORSAIR iCUE software. Verify leak-free connections and perform initial system testing at low pump speed before normal operation.

Usage recommendations

Use compatible fittings and tubing rated for your loop, apply an appropriate thermal paste to the CPU before mounting, and consider adding a CORSAIR iCUE lighting controller (sold separately) for full RGB synchronization. Regularly inspect tubing and fittings for signs of wear and check coolant level and quality per your loop maintenance schedule.
