I had these custom made several years ago for passive cooling some COB (chip on board) LEDs. They were very good at their job but haven't needed them for a long time. If there is any interesting I have 5 more of these, I still have the LEDs too but I am not sure if they're working. I have the LED driver still too. I'd be happy to dig them out and test them if somebody if somebody is interested in purchasing these items, but for now this listing is simply for the one heat sink pictured. This is not designed to be used as a CPU heatsink!!!!!! This is not to go inside your computer!
