      Description

      The N-GV3090GMOC-TC-V2 block directly cools the video cards core (GPU), graphics memory (RAM), and voltage regulator modules (VRM) on both sides of GPUs. By directly cooling these components you can achieve great temperatures along with the ability to reach higher overclocks or extend the overall lifespan of your card by running at below factory temps.

      The block and active backplate are constructed of high purity copper that is electroplated to prevent oxidation. A high flow design is used to allow multiple blocks to run in series. Access to top and bottom G1/4 ports is required on bridge block.

      Specifications
      • Block Material: Nickel Electroplated High Purity Copper / PMMA (Acrylic)
      • Active Backplate Material:  Electroplated High Purity Copper /PMMA (Acrylic)

      Warnings

      This is a repair or replacement-only item. Returns are not accepted on compatibility issues or if the block has had water/fluid run through it.

      The product does NOT include printed instructions. Please check the product gallery images for the installation illustration. The manufacturer reserves the right to alter the block design to expand compatibility. The delivered item may not 100% match the pictured item.

      Generally, thermal pads should be installed on the card where the block has corresponding raised contact points, except the GPU core, which uses thermal paste. Installing pads on other components can lead to improper contact and poor performance.

      Works-ish, has a few flaws

      I don't know how this block performs single. But terrible in a quad set up.
      I've been struggling to get enough water flow to satisfy them. A single card set up the included manifold puts the active backplate in series with the main block. Using the Quad gpu maniford it puts all blocks in parrelell, but the active back plates have a different head pressure than the main block. I'm anly pumping threw a 360x60mm alphacool rad atm to test, playing with 4x D5's combining and mixing series/parrelell set ups to satisfy these. Currently the bent combined flow i could achieve is 18L/min (1080lr/hr) and could not get enough flow rate threw the blocks since they take path of least resistant mainly,and srow right down threw the gpu blocks.
      Due to case restraints i modified the manifold to allow me to set the cards in a reverse parrelell set up to try and help out.

      Durring assembly for some odd reason one block needed modifying so i could line up the inlet/outlet ports. Frustrating but possible.

      Been pluckin away at this set up for a couple weeks now under water, using nothing but fresh distilled water, the active back plates look fine, but the copper coating is already all gone for oddly only the gpu blocks, while the active backplates look fine. I only just discovered this and said nuffs enough time for a review. I'm scared to remove the gpu's to see what the full damage is. Luckily my entire loops is all copper so no mixed metals. But i'm just not sure what to do about the bare copper.
      Please ignore the green hue in the active backplate picture, it's refraction from the ram. I can confirm they're qrystal clear.
      If i'm able to edit reviews i'll update with a picture while i pull the gpu blocks to see the true damage after on a mere couple weeks of use, didn't even get a chance to add inhibitors ar anything, just pure distilled water while i'm waiting for a lga 4189 cpu coper block and finally crack the code to these blocks to get them to have some water flow! Maybe i'll try reversing water flow, tho so far following their included picture to water direction since bykski is notoriously bad with directions /manuals.

      Overal, the block ''works'' i'm sure it'll be fine in a single card system. Or a 3/4 slot 2 card set up using included single card manifold's.
      But so far the quad card set up is terrible and the nickle plating i'm hoping is a ''fluke'' and since I bought all at once was a batch error. Afterall the active barkplates are flawless, it's jush gpu side that's shot.
