I learned about skiving when I started researching building a watercooled PC. Optimus is building some nice heatsinks/water blocks in Chicago. They’re using a micro CNC process for very fine fins in their cold plates, and mention some of the differences on their site. https://optimuspc.com/products/optimus-gpu-replacement-cold-...
Thanks for this link, I was not aware of this company before and they look like an awesome waterblock company. Good USA based alternative to EK (with less selection obv.)
