The NC-3 is a stylish RAM cooler from Jonsbo . The two modules for two RAM bars are easy to install, improve cooling and also come with addressable RGB lighting . The connection is made via a 3-pin RGB connector (5VDG, 5V). Four thermal pads and all necessary mounting material are included in the scope of delivery for installation . All common DDR modules are supported that are equipped with memory chips on both sides (double-sided). For single-sided bars, thicker thermal pads would have to be used - these are not included in the scope of delivery. Note: In order to use the adapter plates, any existing original heat sinks must be removed from the RAM bar to be cooled, which will result in the loss of the manufacturer\'s guarantee.Specification:- Model: NC-3- Colour: ARGB- Specs: 4PCS/box- Dimension: 141MM (W) * 8.5MM (D) * 43MM(H)- Material: Aluminum and ABS- Connector: 5V 3PIN+6PIN- Voltage: 5V RGB- Weight: Net 0.5KGScope of delivery:- 2x RAM cooler- 4x thermal pads- Mounting material
