The Centerpiece of your System


THE HEART OF YOUR COOLINGThe XC7 RGB CPU Water Block combines premium construction, vivid RGB lighting and extreme cooling performance. A precision machined nickel-plated copper cold plate and more 60 high-efficiency micro-cooling fins draw the maximum amount of heat from your CPU, dropping temperatures and letting you push your clock speeds to their maximum. A transparent flow chamber shows off your coolant in all its glory, lit by 16 individually addressable RGB LEDs for 360° of customizable RGB lighting, controlled by adding a CORSAIR Lighting Node PRO or Commander PRO. Powered by CORSAIR iCUE software to deliver nearly limitless lighting customization and control.

Know Exactly what your PC Needs


ADJUST YOUR TEMPERATURE TO YOUR SYSTEMS NEEDSThe XD3 RGB Pump/Reservoir Combo is the heart of your custom cooling system and is ready to unleash it's potential. An adjustable Xylem DDC PWM pump provides powerful flow rate for multi-block loops, while an integrated 180ml reservoir guarantees the XD3 fits easily into most systems, even compact cooling systems. With sixteen built-in RGB LEDs, when combined with a CORSAIR iCUE Lighting Controller and powerful CORSAIR iCUE software, they display vibrant customizable lighting. An included temperature sensor gives you real-time performance data from inside your system, for accurate cooling adjustment. Universally compatible with G1/4 fittings and with both 120mm and 140mm fan mounting brackets included.

Add Ambience to your Cooling


CUSTOMIZE YOUR COOLThe iCUE SP120 RGB PRO Performance Fans include eight individually addressable RGB LEDs each that line the fan hub to create incredible lighting. Enjoy excellent cooling that works in tandem with immersive visuals. The translucent 120mm fan blade spins at speeds up to 1,400 RPM and pushes up to 52 CFM of air. Enjoy excellent performance with high airflow and static pressure without taking the spotlight from your colourful lighting.

Made to Lower the Temperature


DIRECT HEAT AWAYThe XR5 360mm Water Cooling Radiator delivers extreme custom liquid cooling performance, with 30mm radiator thickness and 25 micron thin cooling fins maximizing heat dissipation surface area. A premium copper radiator core core is optimized for use alongside copper CPU and GPU water blocks, further increasing the thermal transfer rate. Intuitive extras such as Integrated Fan Screw Guides and built-in Screw Protection Plates make it easy to install fans, without worrying about damaging the radiator.

Take Control of all your Lighting and Fans
