EVGA 400-HC-1289-B1 RTX 2080 FTW3 Hydro Copper Waterblock

The EVGA Hydro Copper 400-HC-1289-B1 is a purpose-built waterblock engineered to replace the air cooler on EVGA's GeForce RTX 2080 FTW3 series graphics cards. Its full-cover design spans the entire PCB, making direct thermal contact with the GPU die, VRAM modules, and voltage regulation components through a nickel-plated copper base plate. An optimized pin matrix etched into the copper base increases surface area and improves heat transfer to the liquid coolant passing through the block, resulting in lower and more stable temperatures under sustained GPU loads such as gaming, rendering, or compute workloads.

The transparent acrylic top plate lets builders see coolant flowing through the internal channels, adding a visual element to custom loop builds. Pre-installed thermal pads cover all critical contact points, so installation is a matter of mounting the block to the card and connecting standard G1/4" fittings to your existing loop. While the block is strictly limited to EVGA's FTW3 variant of the RTX 2080, owners of that card who run custom water cooling will find it a well-matched, well-built cooling solution that keeps temperatures in check while maintaining the card's boost clock headroom.
