The Shunmaii RAM Radiator Heat Sink is a clip-on aluminum RGB cover designed for DDR4 and DDR5 memory modules. It combines a decorative “armor-style” heatsink shell with 5V 3-pin ARGB lighting, mainly aimed at improving aesthetics in gaming PC builds rather than delivering significant thermal performance gains.
It’s very similar in function to other RGB RAM coolers like ALLOET and is commonly used in glass-side RGB showcase builds.
