Full review

The Corsair H100i Elite Capellix is a 240mm all-in-one liquid CPU cooler designed for enthusiasts and builders who want serious thermal performance without stepping up to a full custom loop. At its core sits Corsair's upgraded pump design, featuring a magnetic levitation pump engine that runs quieter and more efficiently than previous Hydro Series models. Paired with a pair of 120mm ML RGB fans, the radiator dissipates heat effectively even under sustained loads from high-core-count CPUs, making it a popular choice for gaming rigs and content creation workstations alike. The low-profile pump housing also makes installation cleaner, with less interference around tall RAM modules or motherboard VRM heatsinks compared to bulkier coolers.

Visually, the H100i Elite Capellix stands out thanks to Corsair's Capellix LED technology, which packs 33 individually addressable RGB LEDs directly into the pump head. These LEDs are brighter and more power-efficient than traditional RGB lighting, and they allow for vivid, customizable lighting effects that sync seamlessly with Corsair's iCUE software. Through iCUE, users can control fan curves, pump speeds, and lighting patterns, as well as monitor real-time temperatures and system performance. The software integration extends to compatibility with other iCUE-enabled components, letting builders create a cohesive aesthetic and unified control scheme across their entire PC build, from RAM to case fans.

Built with a durable low-evaporation tubing material and a sleek braided sleeve design, the H100i Elite Capellix is engineered for long-term reliability as well as visual appeal. The radiator and fans mount easily into most mid-tower and full-tower cases that support 240mm configurations, and the straightforward bracket system works across major Intel and AMD sockets, including modern LGA 1700 and AM5 platforms with included or separately available mounting kits. Whether used to cool a mainstream Ryzen or Core processor or a higher-end CPU under heavier overclocks, this cooler delivers a balance of acoustic comfort, thermal headroom, and customizable RGB flair that fits well into a wide range of PC component and custom build projects.
