EK-FC1080 GTX Ti FTW3 RGB is a high-performance full-cover water block for EVGA® GeForce GTX 1080 Ti FTW3 based graphics cards, based on NVIDIA Pascal™ architecture (GP102). The water block comes with pre-installed 4-pin 12V RGB LED strip. This water block directly cools the GPU, RAM, and VRM (voltage regulation module) as water flows directly over these critical areas thus allowing the graphics card and it's VRM to remain stable under high overclocks. EK-FC1080 GTX Ti FTW3 RGB water block features a central inlet split-flow cooling engine design for best possible cooling performance, which also works flawlessly with reversed water flow without adversely affecting the cooling performance. This kind of efficient cooling will allow your high-end graphics card to reach higher boost clocks, thus providing more performance during gaming or other GPU intense tasks. Moreover, such design offers great hydraulic performance allowing this product to be used in liquid cooling systems using weaker water pumps. The base of the block is CNC machined out of nickel-plated electrolytic copper while the top is CNC machined out of high-quality acrylic material. The sealing is ensured by quality rubber O-rings. Screw-in brass standoffs are pre-installed and allow for safe, painless installation procedure. This product is compatible with popular RGB sync technologies from all major motherboard manufacturers. The arrow marking on the 4-pin LED connector is to be aligned with the +12V marking on the RGB header. EKWB recommends the purchase of aesthetic retention backplate which improves the looks of your graphics cards and also provides some passive cooling to the circuit board VRM section. The EK-FC1080 GTX Ti FTW3 RGB water block is compatible with EK-FC1080 GTX Ti FTW3 Backplates and the factory EVGA backplate as well.
