Product description:

Granzon gives you the power to perform at your peak and create stunning visuals. We push the boundaries of innovation, and our products are unrivaled in quality. Our products are a perfect blend of art and technology. This full coverage block directly cools the graphics cards core (GPU), graphics memory (RAM), and voltage regulator modules (VRM). By directly cooling these components, you can achieve great temperatures and reach higher overclocks or extend the overall lifespan of your card by running at below-factory temperatures.

The block is constructed of high-purity copper that is nickel electroplated to prevent oxidation. A high-flow design is used to allow multiple blocks to run in series. Top and bottom ports can be used to configure parallel or serial designs in multi-block setups.



Block material: nickel electroplated high purity copper 

Armor material: black anodized aluminum (not in contact with coolant)
