This article covers NZXT Kraken 120 RGB水冷CPUクーラー.

Overview

The NZXT Kraken 120 is a 120mm all-in-one liquid CPU cooler designed for compact builds. It combines a slim radiator with a customizable RGB pump cap and a quiet Aer P radiator fan, making it a solid choice for gamers and PC enthusiasts who need efficient cooling in a small footprint. With support for Intel LGA1700/1200/115x and AMD AM5/AM4 sockets, the Kraken 120 handles CPUs up to around 200W TDP. The pump features an improved thermal chamber for better heat transfer, while the 120mm fan uses fluid dynamic bearings for quieter operation at up to 2000 RPM (33 dBA max).

Connectivity & Compatibility

The cooler connects via standard 4-pin PWM headers for both pump and fan. RGB lighting is managed through NZXT's RGB controller, which can be integrated with motherboard RGB headers or daisy-chained with other NZXT RGB products. The pump head height is approximately 52mm, fitting most mid-tower and small-form-factor cases without clearance issues. However, the 120mm radiator's cooling capacity is limited compared to 240mm or 360mm models. It is not recommended for high-end CPUs like Core i9 or Ryzen 9 under sustained full load. Always check your case's radiator support (120mm fan mount) and GPU length before purchasing.

Product Info

Released in late 2021, the Kraken 120 sits in the entry-to-mid-range segment of the AIO cooler market. It carries a 3-year manufacturer warranty and includes Intel/AMD mounting kits, backplate, thermal paste, RGB controller, and manual. The official model number is RL-KR120-B1 (FN1640 for the Japanese market).

Best Use Cases

Small form-factor builds: Ideal for Mini-ITX or Micro-ATX cases where tower air coolers won't fit. The 120mm radiator fits most compact chassis. Quiet PC enthusiasts: The FDB fan and pump are nearly silent at idle. However, under heavy load the fan ramps up audibly; for absolute silence, consider a larger radiator. * RGB customization fans: The addressable RGB pump cap and ring LED can be customized via NZXT CAM software, offering a wide range of colors and effects. ## Alternatives
Direct competitors include the Cooler Master MasterLiquid ML120L V2 and Corsair H60x RGB Elite. The ML120L V2 offers pump-integrated RGB, while the H60x RGB Elite works within Corsair's iCUE ecosystem. The Kraken 120 stands out with NZXT CAM's intuitive software and daisy-chain connectivity for multiple NZXT RGB devices.

Things to Consider

A 120mm AIO often performs similarly to or slightly worse than a mid-range tower air cooler at the same price point (e.g., Noctua NH-U12S). For Ryzen 9 or Core i9 CPUs, thermal throttling may occur under sustained loads; a 240mm or larger AIO is recommended instead. The pump's lifespan is roughly 5 years, so plan for eventual replacement. Radiator thickness is about 27mm, which fits most cases, but front-mounting may interfere with long GPUs. Always verify your case's radiator support and GPU clearance before purchase.
