The NC-3 is a stylish RAM cooler from Jonsbo. The two modules for two RAM sticks are easy to install, enhance cooling, and come with addressable RGB lighting. The connection is made via a 3-pin RGB connector (5VDG, 5V). Four thermal pads and all necessary mounting materials are included in the package. It supports all common DDR modules that are populated with memory chips on both sides. For single-sided modules, thicker thermal pads would need to be used - these are not included. Note: To use the adapter plates, any existing original heatsinks on the RAM sticks may need to be removed, which may void the manufacturer's warranty.
