Two silver JONSBO memory heat sinks with RGB lighting. - Brand: JONSBO - Model: Memory Heat Sink - Color: Silver - Features: RGB lighting - Quantity: Set of 2 - Included: Mounting parts, thermal pads These are 5v argb compatible memory heat sinks. I have been using them with DDR4 memory, but I no longer need them, so I am selling them. - Compatible only with single-sided memory (chips on one side). Please note. - The thermal pads show considerable signs of use. They are placed between the heat sink and the memory, so they are not visible once installed, but please be aware of this. Thank you for looking.
