The CORSAIR iCUE H170i ELITE CAPELLIX XT Liquid CPU Cooler provides powerful, high-performance cooling for your processor, with CORSAIR AF RGB ELITE fans, a 420mm radiator, and ultra-bright CAPELLIX LEDs. All-in-one liquid coolers don't dissipate processor heat inside the case like traditional air coolers, but instead guide it to the edge of the case and blow it out with dedicated fans. This results in cooler components and less noise. The ELITE CAPELLIX XT is an upgrade to our most powerful CPU cooler. CORSAIR AF RGB ELITE PWM fans deliver massive low-noise airflow with AirGuide technology for extreme CPU cooling performance. Anti-vortex vanes ensure more uniform airflow over radiator fins and more optimal heat dissipation. All ELITE CAPELLIX XT AIOs include pre-applied CORSAIR XTM70 Extreme Performance thermal paste for maximum heat transfer from your high-end processor to the cooler cold plate. For reliably high cooling performance, every step in the heat transfer and dissipation chain matters. The ELITE CAPELLIX XT cooler pump head houses 33 ultra-bright CAPELLIX LEDs to go along with its RGB fans. When you add powerful, low-noise cooling to the mix, your system will look great and will run even better. When you want to take it to the next level, you can upgrade your CPU cooler by swapping the original pump cap with the ELITE LCD Upgrade Kit. An included iCUE COMMANDER CORE RGB lighting and fan speed controller gives you precise speed and lighting control over up to six CORSAIR RGB fans. Extended tubing length of 400mm (H100i, H115i) / 450mm (H150i, H170i), modular tool-free mounting brackets, and pre-applied XTM70 thermal paste make for easy installation on the latest Intel® and AMD® motherboard sockets, including LGA 115X, 1200, 1700, 2011, and 2066, plus AMD Socket AM4, AM5, and sTRX4/sTR4.
