Product information: EK-FC7970/R9 280X - Acetal CSQEK-FC7970 Acetal CSQ is a high performance full-cover water block for AMD reference design Radeon HD 7970 and -7950 graphics card.
This water block directly cools the GPU, RAM as well as 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-FC7970 water block also features a very high flow design therefore it can be easily used in liquid cooling systems using weaker water pumps.
Base is made of electrolytic copper while the top is made of quality POM Acetal material. The sealing is performed by quality rubber washers. Screw-in brass standoffs are pre-installed and allow for safe, painless installation procedure. Block is mounted with enclosed M3x4 DIN7985 screws.
EKWB recommends the purchase of aesthetic retention backplate (EK-FC7970 Backplate - Black CSQ) which improves the looks of your graphics cards and also provide some passive cooling to the VRM section.
