You will find options with pure copper cores, which differ from the aluminum cores often found in pre-built kits. Some alternatives are slimmer, such as the 1.18-inch thick models, while others offer denser fin packs for custom loops. This guide compares these specs to help you find the right fit for your hardware.
Our top pick: Lian Li Galahad II Trinity 240 Black ARGB.
How these alternatives compare
Alphacool NexXxos 240mm Full Copper Radiator
The Alphacool NexXxos 240mm Full Copper Radiator is a standalone component rather than an integrated all-in-one system. It lacks pre-mounted fans and built-in lighting, which means you must source your own fans and controllers. This makes it ideal for custom loop builders who want proven copper performance without extra electronics. Unlike the Lian Li, which offers a complete plug-and-play solution with ARGB and a five-year warranty, this unit requires more assembly effort. You gain material purity and standard fittings but lose the convenience of a ready-to-install kit. It suits users prioritizing copper internals over all-in-one convenience.
Alphacool NexXxos UT60 240mm Radiator
The Alphacool NexXxos UT60 240mm Radiator is a dense, slim cooling solution designed for constrained spaces. It features six connection points, offering more flexibility for custom loop tubing routes than the Lian Li’s fixed design. This radiator is all-copper and lacks any integrated fans or lighting, requiring you to manage airflow and aesthetics separately. While the Lian Li provides 89.1 CFM airflow out of the box, this unit relies on your chosen fans. It is best for custom loop enthusiasts who need a compact footprint and dense copper surface area. You trade the Lian Li’s integrated convenience for specialized, space-saving custom loop compatibility.
Alphacool NexXxoS Monsta 240mm Radiator
The Alphacool NexXxoS Monsta 240mm Radiator is a solid choice for custom loop builders who prioritize copper construction. It is a standalone radiator without pre-mounted fans or ARGB lighting, differing significantly from the Lian Li’s all-in-one approach. This unit requires you to source compatible fans and control hardware separately. It fits standard 240mm mounting patterns but lacks the integrated controller found in the Lian Li CPU head. This option is for users who want heavy-duty copper performance and standard compatibility. You give up the ease of installation and included lighting in exchange for a pure, high-quality copper core that integrates into a custom loop system.
Alphacool NexXxos ST30 240mm Copper Radiator
The Alphacool NexXxos ST30 240mm Copper Radiator is a slim, high-performance cooling solution for builds with limited space. It measures 1.18 inches thick, making it suitable for slim cases where the Lian Li’s 1.1-inch radiator might also fit, but without the pre-mounted fans. This unit is all-copper and lacks any integrated electronics or lighting. You must provide your own fans and control systems. It is best for builders who value copper internals and compact dimensions over the convenience of an all-in-one kit. Unlike the Lian Li, which offers a complete package with a five-year warranty, this radiator is a component for custom loop assembly.
Alphacool NexXxos XT45 X-Flow 240mm Copper Radiator
The Alphacool NexXxos XT45 X-Flow 240mm Copper Radiator is designed for custom loops prioritizing copper core performance. It features standard G1/4 inch ports and lacks pre-mounted fans or ARGB lighting, unlike the Lian Li. This radiator is heavier and requires you to source all peripheral components. It is ideal for users who value material purity and heavy-duty construction over lightweight convenience. The Lian Li offers a complete, integrated solution with included fans and a controller. This Alphacool unit provides a pure copper core for custom builders who are willing to assemble and manage their own fan and lighting setups for maximum thermal performance.
Alphacool NexXxoS ST25 240mm Copper Radiator
The Alphacool NexXxoS ST25 240mm Copper Radiator is a slim, all-copper core designed for maximum thermal performance. It lacks pre-mounted fans and lighting, requiring you to integrate it into a custom loop with separate components. This contrasts with the Lian Li’s all-in-one design, which includes fans and ARGB out of the box. This unit is best for builders who demand material purity and compact dimensions. You gain a dense copper core suitable for tight spaces but lose the plug-and-play convenience and integrated controller of the Lian Li. It is a specialized component for custom loop enthusiasts who prioritize copper construction over all-in-one ease.
