How alternatives compare to KAGAUOAS
Phanteks Glacier One 360mm AIO
The Phanteks Glacier One 360mm AIO differs significantly as a complete all-in-one unit rather than a custom loop component. It measures 15.6 inches in length and weighs 2.43 pounds, offering a white finish. This model supports AM4, AM5, and LGA 1700 sockets with RGB lighting. It is ideal for users prioritizing VRM cooling and clean cable management. Unlike the KAGAUOAS block, it does not require custom tubing or fittings. You get a pre-filled system with a mesh pump cap. Choose this if you want functional benefits and a single-cable setup without building a loop from scratch.
EK AIO 120mm D-RGB Liquid Cooler
The EK AIO 120mm D-RGB Liquid Cooler is a compact 120mm unit designed for smaller cases or older platforms. It weighs 3.09 pounds and supports the AM4 socket. The D-RGB lighting allows for visual synchronization across your build. Its dimensions are 8.27 inches wide and 10.2 inches high. This cooler is a solid choice when space is limited. It gives up the multi-DIMM coverage of the KAGAUOAS block in favor of CPU cooling in tight spaces. Pick this alternative if you need customizable lighting and socket compatibility for older hardware rather than RAM-specific cooling.
Fo Sa 360mm Copper Radiator
The Fo Sa 360mm Copper Radiator is a passive component for custom loop builders. It is made of copper and features G1/4 threads for standard fittings. The unit weighs 15.9 ounces and comes in a 360mm size. It lacks any fans or pump, serving only as a heat exchange surface. This differs from the KAGAUOAS block by providing large surface area for heat dissipation. You must supply your own fans and tubing. Choose this if you are assembling a custom loop and need high-quality copper parts for efficient cooling rather than a ready-to-mount component.
FOSA 480mm Copper Radiator
The FOSA 480mm Copper Radiator offers even more surface area than the 360mm version. It is a 480mm copper radiator with G1/4 threads, weighing 15.9 ounces. This component is designed for cases that support large radiators. It fits users who already have fans and pumps ready to install. Unlike the KAGAUOAS RAM cooler, this provides maximum cooling potential for a custom loop. It gives up direct component coverage for sheer thermal mass. Pick this alternative if you need maximum surface area in a 480mm form factor for your custom loop build.
TT Racing AM4/AM5 Aorus RGB Bracket
The TT Racing AM4/AM5 RGB Bracket is a specialized mounting piece for AM4 and AM5 builds. It supports 280mm Aorus AIOs with RGB integration. The bracket measures 3.1 inches wide, 0.2 inches high, and 4.3 inches long. It provides precise socket compatibility for specific AIO models. This differs from the KAGAUOAS block by being an accessory rather than a cooling component. It does not cool RAM directly. Choose this if you need to mount a specific AIO to your socket platform with RGB synchronization, rather than cooling memory modules with a custom block.
ARCTIC Liquid Freezer II 280 RGB Cooler
The ARCTIC Liquid Freezer II 280 RGB Cooler is a complete AIO solution for LGA1700 builds. It weighs 4.87 pounds and includes a controller for fan speeds. The unit measures 6.11 inches wide, 6.7 inches high, and 14 inches long. It features integrated cable management and RGB illumination. This cooler offers tidy RGB cooling without custom loop complexity. It gives up RAM-specific cooling for comprehensive CPU cooling. Pick this alternative if you need LGA1700 support and value integrated cable management over the modular nature of a custom loop block.
