BLEMISH - Signature V2 CPU Block - Intel

BLEMISH BLOCK SALE - 30% OFF

"Blemish" blocks are A+ performance blocks with small cosmetic imperfections.

We're hyper about quality and we only ship perfect A+ grade product. Of course, this means we have numbers of blocks didn't make the cut. Anything from smudge on a cold plate to a tiny scuff on a bracket will make a product a "blemish".

Blemish blocks will typically look like A-grade in a final PC build. The blemishes are typically only visible when examining up close.  In some cases, you may not even be able to find the blemish. Sometimes the blems are in the cold plate fins, so specs or marks are visible, but performance isn't affected. 

NOTE: we cannot send pictures of each blemish block to pick and choose.

  • A++ Optimus performance
  • Includes all hardware, instructions, paste, etc.
  • Imperfections can be: small scratches, scuffs, slight color differences, etc.

Leveraging our experience in aerospace manufacturing, the Signature V2 features many industry-only and world-first features not seen in consumer hobby-grade liquid cooling parts. The Signature V2 is the top choice for high performance PCs, from artificial intelligence and high frequency trading to CG rendering and all around performance.

MAXIMUM COOLING FOR THE LATEST INTEL CPUS


The Signature V2 is custom made for modern Intel CPUs, the latest 9th gen+ and HEDT models with higher cores and even higher thermal requirements. Due to the Signature V2's extreme cooling, you can achieve bigger overclocks with lower temps. If you're chasing world records on liquid, the Signature V2 is the best block in the world.

PERFORMANCE-FIRST DESIGN


Never ones to stop innovating, the Optimus Signature V2 outdoes our own Signature V1, recognized as the best CPU block ever made. The V1 achieved numerous "world's firsts" including the finest CNCed fins, best construction and, most importantly, top cooling for the latest CPUs.

The V2 builds on the V1 and provides up too an extra 2-7 degrees better cooling. We've upgraded our cold plate to the Gen2 design with even higher surface area and finer cold plate finish. A new flow channel design takes advantage of the Gen2 cold plate, simultaneously increasing thermal dissipation and flow rate.

ZERO FLEX UNIBODY CONSTRUCTION


A CPU block is only as good as the pressure it applies on the CPU, allowing thermal transfer from the IHS to the fluid.To achieve the absolute perfect pressure, our unibody design has zero flex, even surpassing our own Foundation CPU blocks, which already set a new bar for rigidity.

Creating a unibody block means starting with a solid 3.25 lb block of US-sourced ultra pure 360-grade brass. The top, legs, sides, everything except the cold plate is one single piece. Achieving this level of precision is both extremely time consuming and exacting. Any imperfections can't be covered up or compensated.

BANISHING FLAKY ELECTROPLATED NICKEL

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?

PRO-XE NICKEL

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.

SAFE FOR H2O

Aside from reliability, our Pro-XE 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.

MEASURABLY PERFECT FINS


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.

CNC VS SKIVED FINS


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 and fin 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.

INTEGRATED VS STEEL JET PLATES


The Optimus Signature V2 features an integrated jet design to force fluid through the fins to maximize heat dissipation. Other designs on the market use a cut steel jet plate to create pressure. While cheaper to manufacture, the steel jet plates often rust and cause galvanic corrosion when in contact with the fins, causing problems in the loop. By integrating the jet design into the unibody block, the Signature eliminates steel from the loop, reducing potential for rust and corrosion. Moreover, we're able to tailor the cold plate bow to match the CPU IHS perfectly.

FAQ

  • COPPER VS NICKEL COLD PLATE? Choose raw copper for highest theoretical performance (depends on overclocking and overall system). Choose nickel for aesthetics and/or liquid metal compatibility
  • ACRYLIC VS ACETAL? Our cast acrylic is actually far stronger than acetal, the traditional professional choice. Acetal won't ever crack, but it's soft and will deform with pressure and easily scratch. Our cast acrylic will survive far more abuse than acetal. So for all users, acrylic is recommended, unless you want the black look.
  • LIQUID METAL? BARE DIE?Go for it! Remember, liquid metal will etch copper immediately, though some builders like the performance of pure copper. Liquid metal will discolor nickel, but etching will take far longer. In both cases, the performance of the cold plate won't be affected.
  • THERMAL PASTE? We include US-made Ceramique thermal paste. However, numerous thermal pastes are also excellent. Thermal Grizzly Kryonaut and Arctic MX4 2019 are two of the highest performance we have tested.
  • FLOW DIRECTION? Fluid needs to flow in a specific direction -- center of fins and then out. On acrylic blocks, the "in" is connected to the center channel. On acetal blocks, the "out" shows the fins inside, while the fins can't be seen on the "in" port.
  • FLUSHING?All Optimus products have already been cleaned before shipping. You'll only need to flush your radiators and non-Optimus products. In fact, heavy system prep chemicals can be detrimental if they remain in small quantities in your loop. This can easily happen with fluid pressurized into o-ring grooves through heating.
  • CLEANING? Microfiber is your friend. Dish soap and water is ideal for our products. Always use microfiber glass cloths to prevent any scratches, especially on cold plates. Do not scrub, simply hand rinse. Isopropyl alcohol is not needed and can cause discoloration.
  • COPPER OXIDATION? Copper will immediately begin to oxidize (turn brown) when exposed to air. This is normal and expected and won't affect performance unless the oxidization is extreme, like the Statue of Liberty. But you're not leaving your blocks out by the ocean, are you?
