The crew at techPowerUP, despite saying EVGA Hydro Copper GTX 1080 water block being very expensive and providing relatively poor GPU and VRM thermal performance, gave the GPU water block a score of 8.2 out of 10. 😕
As mentioned above, the Hydro Copper GTX 1080 is a full cover block in that it covers and cools the GPU core, VRAM, and VRMs. The design does not appear to have changed from when EK made these, with a monochrome color scheme, an EVGA cutout in the front aluminum fascia, a long six-port manifold, and integrated lighting.
