Bykski N-AS4090STRIX-X-V2 Full Coverage GPU Block + Backplate for ASUS  TUF Gaming GeForce RTX 4090/ROG Strix GeForce RTX4090/O24GWHITE/GAMING/ROG STRIXGEFORCE RTX 4090D 24G GAMING G1/4

TL;DR: This full coverage block directly cools the GPU core, graphics memory (RAM), and voltage regulator modules (VRM) on supported ASUS RTX 4090 cards. The block uses nickel electroplated high purity copper with acrylic, paired with a black anodized aluminum backplate that is not in contact with coolant.

This full coverage block directly cools the video cards core (GPU), graphics memory (RAM), and voltage regulator modules (VRM). 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 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.

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 manufacturer reserves the right to alter the block design to expand compatibility. The delivered item may not 100% match the pictured item. The product does NOT come with English instructions. Please see the product gallery images for the install guide if available. 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.

Not responsible for any damage caused by or when using this product. Please use it at your own risk.
