Replacement CPU Cold Plates

Individual Optimus Gen2 cold plate with latest micron fin design, providing even higher surface area, flow and cooling. Both plates will provide extreme cooling for all applications. Some builders prefer raw copper because it provides the best heat transfer. Our electroless nickel finishes are extremely fine and provide industry-best nickel heat transfer.

  • Choose corrosion-proof electroless nickel finish when using liquid metal.
  • Choose raw copper for absolute highest performance.

COMPATIBILITY: Signature V2 Block, Foundation Blocks (Intel+AMD). Not compatible with the Signature V1 block.

NOTE: Lines and shadows seen in the pictures are due to monitor interlacing and scaling as well as photography. Our fins are so fine, they cause moire patterns on monitors.

Select Cold Plate Finish:



Taking our world's best cold plate design to the next level with the industry's finest fins, highest surface area and best heat dissipation. Our 100% CNCed cold plate sets a new bar for Intel and AMD cooling performance.



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 achieve 0.1016mm (0.004”) fins with 0.2032mm (0.008”) micro channels. This isn't just superior craftsmanship, it's generations beyond other fin designs.



Optimus fins and channels are perfect from first to last. It has taken years to create the tools needed for this level of accuracy, but the thermal benefits are worth it. This makes Optimus the world’s first and only truly micro CNC fin cold plate on the market. By achieving thinner fins, the Optimus cold plate has the most surface area of any CPU block available. And surface area = cooling performance.


In water cooling, there are two ways to manufacture fins: CNCing and skiving. Unlike the CNC process Optimus uses, skived fins are created by scraping a blade across a metal block, then flipping that shaving up to create a fin. While skived fins are the most common type and found in all-in-one units and water blocks, the shaving-style fins are never straight andfin collapse happens with nearly every skived plate. Open an AIO and see what has happened to the fins, upwards of a quarter of the fins will have deformed on the edges from the pressure of the o-rings and block tops, blocking flow channels, even breaking off.

CNC fins are typically much thicker than skived fins. Look at most open loop water blocks, the fins are quite large. The downside is the surface area is much lower compared to thin-fin designs.That's why the Optimus ultra thin CNC fins are the best of both worlds -- the highest surface area with CNC precision to ensure long lasting performance.


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, including opaques, 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 fittings survive basic H2O?

Alas, eletroplated nickel is the PC industry standard. What's the solution?


Optimus parts are finished with only industrial-grade corrosion-proof nickel, called electroless nickel.Electroless is an aerospace industry finish with extreme chemical resistance, hardness and superior fluid lubricity. So why isn't everyone using electroless? Cost and appearance. 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 .


Aside from reliability, electroless nickel is able to withstand saltwater, corrosive chemicals and, yes, even plain water.With Optimus, you can use distilled water without fear of flaking. Distilled, aside from being cheap, is also the highest performance coolant readily available. Anti-corrosive additives lower the thermal conductivity of the liquid.That's why we can offer a 10 year warranty, even with regular H2O. It has been a herculean task to create Optimus's electroless products, but the results look great and are nearly indestructible.


Optimus sets another record for flattest cold plate on the market. Optimus machines blocks less than 1 micro-inch (µin) in flatness. This is 0.000025mm of roughness (measuring the peaks and valleys of the surface).Other companies are over 400% rougher than Optimus coldplates.

The only way to truly guarantee 0.000025mm level of accuracy is to CNC the cold plate perfectly with diamond bits. Optimus created proprietary diamond tooling that allows the cold plates to come off the CNC with a perfect mirror finish.

Additionally, because we control the fins and cold plate to such a precise level, we can make the distance between CPU IHS and the fins extremely small. Thin cold plates are able to transfer heat from the CPU faster than thicker cold plates.
