ZADAC now offers an M.2 RGB heat spreader. It is an M.2 heatsink that cools NVMe SSD, embedded with addressable RGB built in. By itself, not big news, but admittedly I do like the looks of this one.
Detailed specifications are unknown at present but it should be compatible with most M.2 SSDs sold in the market. Remember though, you need a compatible motherboard with 5V pins for the RGB part. Zadac mentions "It has a phenomenal heat diffusion capability", and that can be seen from the looking down image cut that it is a considerably thick heat sink.
