6 Best Alternatives to the Phanteks Glacier One 360mm RGB (2026)

How each alternative compares

Phanteks Glacier One 420D30 X2 AIO Cooler

The Phanteks Glacier One 420D30 X2 offers a larger 420mm radiator compared to the 360mm unit. Its dimensions are 20.1 inches long, which exceeds the 15.6-inch length of the original. This extra surface area provides superior cooling for VRMs and memory modules. It retains the Evolv X2 pump cover design and D-RGB lighting. You should choose this if your case supports larger radiators and you need maximum thermal headroom for high-end CPUs. It sacrifices case compatibility for increased cooling capacity. The weight increases to 5.07 pounds, requiring sturdy mounting. This model is ideal for enthusiasts who prioritize thermal performance over compactness.

Thermalright 47mm Low-Profile CPU Cooler

The Thermalright AXP90 X47 is a low-profile air cooler with a height of 47mm. This is significantly shorter than the 1.06-inch height of the Phanteks AIO. It lacks liquid cooling and RGB lighting, focusing instead on compact fitment. It supports the same major sockets, including AM5 and LGA 1851. You should pick this if you are building in a small ITX case with strict height limits. It cannot match the cooling power of a 360mm AIO for high-TDP processors. The weight is just 1.1 pounds, making it very light. It is a specialized solution for builders who must prioritize fit over raw thermal performance.

Thermalright AXP90 36mm Low-Profile Cooler

The Thermalright AXP90 X36 is an even more compact air cooler at 36mm height. It is shorter than the 47mm Thermalright model and the Phanteks AIO. It uses a single fan and lacks RGB lighting. It supports standard sockets like AM4 and LGA 1700. You should choose this for ITX builds with extreme height constraints. It delivers adequate cooling for modest CPUs but lacks the capacity for high-end gaming rigs. The weight is 15.8 ounces, lighter than any liquid cooler. It gives up significant cooling power for the sake of fitting into tiny cases. This is a niche option for builders who cannot accommodate taller coolers.

Thermalright Peerless Assassin 120 Black Cooler

The Thermalright Peerless Assassin 120 Black is a dual-tower air cooler with six heat pipes. It lacks the liquid cooling and RGB lighting of the Phanteks model. Its height is 6.24 inches, which may interfere with tall RAM modules. It supports AM5 and LGA 1851 sockets. You should pick this if you want strong cooling performance in a mid-tower case without liquid maintenance. It fits users who prioritize thermal efficiency over aesthetic lighting. The weight is 2 pounds, similar to the AIO. It offers solid performance for mainstream CPUs but lacks the VRM cooling feature of the Phanteks pump cover.

Cooler Master Hyper 622 Halo Dual-Tower Air Cooler

The Cooler Master Hyper 622 Halo is a dual-tower air cooler with six heat pipes. It features ARGB lighting, similar to the Phanteks D-RGB. Its height is 6.3 inches, taller than the Phanteks AIO. It supports AM5 and LGA 1851 sockets. You should choose this if you need modern socket support with visible RGB effects in a standard ATX case. It delivers strong cooling for powerful processors without liquid cooling risks. The weight is 2.78 pounds. It lacks the dedicated VRM and M.2 cooling of the Phanteks Evolv X2 design. It is a robust air cooling option for builders who prefer traditional towers.

Thermalright Assassin X 120 RGB CPU Cooler

The Thermalright Assassin X 120 RGB is a slim air cooler with four heat pipes. It has a height of 5.83 inches and weighs only 3.53 ounces. It lacks the liquid cooling and VRM cooling of the Phanteks model. It features RGB lighting and supports major sockets. You should pick this for compact cases and standard desktop builds. It handles standard workloads well but lacks capacity for high-end gaming. It is an affordable option that gives up significant thermal performance. It is ideal for users who need a slim profile and basic lighting without the complexity or weight of an AIO liquid cooler.
