How the alternatives compare

Alphacool NexXxoS XT45 180mm Triple Radiator

The NexXxoS XT45 180mm Triple is a compact copper radiator designed for space-constrained builds. At 23 inches wide and 7.17 inches long, it is significantly smaller than the 17.4-inch long original. This model weighs 4.73 pounds, making it much lighter than the 10.2-pound 1260mm version. It uses a 180mm size format, which limits its total cooling surface area. You should choose this option if your case cannot accommodate the larger 1260mm footprint. It retains the full copper construction for reliable heat dissipation. However, you sacrifice raw cooling capacity for a form factor that fits in small chassis. It is ideal for builders who prioritize fit over maximum thermal headroom.

Thermaltake Pacific C240 Copper Hard Tube Kit

The Thermaltake Pacific C240 Copper Hard Tube Kit includes a 240mm radiator rather than a 1260mm unit. This kit is an all-in-one solution for hard tube loops, prioritizing ease of assembly. It weighs less than the original Alphacool model, though specific weight data is not listed. The dimensions are 20.7 inches long and 16.1 inches wide. This product is best for users who want a complete copper aesthetic with DDC pump compatibility. You give up the massive surface area of the 1260mm radiator for a more manageable 240mm setup. It suits builders who value streamlined installation and copper fittings over extreme cooling potential. It is not a direct radiator replacement but a complete loop component set.

Alphacool NexXxoS UT60 1080mm Copper Radiator

The NexXxoS UT60 1080mm is a dense copper radiator measuring 14.2 inches long and 14.9 inches wide. It supports nine 120mm fans, whereas the original supports 140mm fans. This unit weighs 8.2 pounds, which is lighter than the 10.2-pound original. It offers high performance in a compact frame, prioritizing copper performance over maximum length. The height is 2.56 inches, making it thicker than the original. You should pick this if you need dense cooling in a smaller footprint. It provides similar material quality but with a different fan configuration. This option is ideal for builders who want strong thermal performance without the bulk of the 1260mm model. It fits compact high-performance loops well.

YXHGeeek RTX 4090 AMP Copper GPU Water Block

The YXHGeeek RTX 4090 AMP Copper GPU Water Block is a specialized component for Zotac RTX 4090 AMP graphics cards. It is not a radiator but a water block for GPU cooling.
