This is the original V1 model of the Lumen cooler. There was a defect detected with this model that was replaced with a claim honored by Fractal Design (More information here: https://www.guru3d.com/story/fractal-lumen-water-cooler-recall-cooland-issue-raises-cpu-temps/#:~:text=Fractal%20Design%20has%20uncovered%20a,cooling%20block%27s%20fins%2C%20lowering%20temperatures.)

I used this cooler for 6 months with no issues, and kept it as a spare after claiming the recall with the manufacturer. It performs well and kept my 5900X well cooled. All parts for compatibility with AMD and Intel CPUs are included. If you have any questions please feel free to message me.
