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