The pure copper beefy block is $250 made in Chicago
What we bought is the XE nickle
Flaking, disintegrating nickel is a widespread problem in liquid cooling. After all, nickel PC fittings and blocks prohibit use with plain water, or you void the warranty. Instead, you must use anti-corrosive fluids to protect nickel components. Why? Because the industry standard electroplated (aka electrolytic) nickel is a cosmetic nickel finish that isn't meant to be used in liquid applications. Often called chrome or shiny nickel, electroplated nickel is cost effective and looks good.
Unfortunately, water, anti-fungals and fancy fluids will rapidly strip electroplated nickel. The gunk that will appear in block fins isn't just broken down fluid, it's often disintegrated nickel, paint and cheap plastics. If this seems crazy, it is. After all, the cheapest home faucet can handle tap water, so why can’t expensive PC parts?
"Optimus parts are finished with our proprietary nickel process called Pro-XE. Pro-XE Nickel is an industrial-grade professional
electroless nickel plating. Electroless is an aerospace industry finish with extreme chemical resistance, hardness and superior fluid lubricity. Pro-XE is specially tailored for liquid cooled PC components with both extreme corrosion resistance and excellent visual appearance. So why isn't everyone using electroless? Electroless is far more difficult to manufacture, especially when achieving perfect finishes needed for premium PC builds. And electroless can't achieve that easy chrome look of electroplating, which is why electroplating is the industry standard, even if it shouldn't be used."
THE FINEST FINS EVER CREATED
Over three years of development went into creating our truly next-level patent-pending fin technology. Using a fully CNC machining process, Optimus is able to achieve101 micron (0.1016mm, 0.004”) fins with 202 micron (0.2032mm, 0.008”) micro channels. This isn't just superior craftsmanship, it's generations beyond other fin designs. everything that they do and every aspect of their blocks are meant for extreme performance. I felt like their plating was very suitable for liquid metal. In addition to having the flatest coldplate which i needed for my direct die liquid metal 10900k. Guess what,
53 C max temp in cinebench r15 at 5.2Ghz Anyone who uses their blocks reports significantly better temperatures compared to ANY other block on the market and i can attest to that
Even gamers nexus was raving about the supreme performance and he doest rave about anything so there's that
