This guide compares the Thermalright Frozen Notte 360 Black ARGB V2 against the Alphacool D-RAM Cooler X4 Universal. While the primary keyword thermalright vs alphacool aio liquid cooler suggests a direct CPU cooling battle, these products serve entirely different roles. The Thermalright unit is a complete 360mm AIO system designed for processor heat dissipation. In contrast, the Alphacool component is a passive heat sink intended solely for RAM modules. Understanding this functional divide is critical before you proceed.

Verdict: These products address distinct hardware needs and are not interchangeable. Choose the Thermalright Frozen Notte if you need primary CPU cooling. Select the Alphacool D-RAM Cooler only if you require dedicated memory heat dissipation for a custom loop.
CPU Cooler vs RAM Block
Primary Function
The Thermalright Frozen Notte 360 Black ARGB V2 is designed as an all-in-one CPU liquid cooler. It features a 360mm radiator and a pump block intended to remove heat directly from the processor. In contrast, the Alphacool D-RAM Cooler X4 Universal is a component-specific accessory. It is built to cool four RAM modules rather than a CPU. This fundamental difference means they solve distinct thermal problems. You cannot swap their roles. One manages core processor temperatures, while the other targets memory module heat buildup. Choosing between them depends entirely on which component you need to cool.
Socket Compatibility
Thermalright lists extensive socket support for its CPU cooler. It works with Intel LGA 1150, 1151, 1155, 1156, 1200, 1700, 1851, 2011, and 2066. It also covers AMD AM4, AM5, AM2, AM2+, AM3, AM3+, FM1, FM2, and FM2+. The Alphacool unit has no listed CPU socket compatibility. It is a universal RAM block that attaches to memory slots. If you need a CPU cooler, only the Thermalright option fits. The Alphacool product does not provide mounting hardware for any processor socket, making it incompatible for CPU cooling tasks.
Radiator Size
The Thermalright Frozen Notte 360 uses a 360mm radiator. This large surface area helps dissipate heat from the CPU loop effectively. The Alphacool D-RAM Cooler X4 has no radiator. It is a small block measuring 128 x 45.2 x 11.1mm. It relies on existing airflow or custom loops for cooling. It does not include fans or a heat sink matrix. If you want a complete cooling solution with a large radiator, the Thermalright unit is the only choice. The Alphacool block requires you to provide your own cooling infrastructure.
Lighting
Thermalright includes full ARGB lighting. The fans and water block support 5V 3-pin ARGB synchronization with motherboards. It offers 1600W color effects that can be connected in series. The Alphacool D-RAM Cooler X4 Universal does not list any lighting features. It is a functional block made of copper, acetal, and acrylic. It focuses on thermal performance and material aesthetics rather than programmable LEDs. If RGB synchronization is a priority, the Thermalright cooler provides this capability. The Alphacool block offers no lighting options.
Material Construction
Thermalright uses a full copper mirror plane base and black aluminum fins. The tubing is a high polymer woven protective pipe. The Alphacool D-RAM Cooler X4 uses copper and acetal for the block, with an acrylic top. Acrylic is often preferred for visibility in custom loops. Thermalright prioritizes heat transfer materials like copper and aluminum for its CPU block. Alphacool uses durable plastics and metals for its RAM block. The materials reflect their different purposes. Thermalright aims for maximum thermal conductivity, while Alphacool balances durability and visual appeal for memory cooling.
