EK-FC580 DCII is a high performance full-cover water block for ASUS custom DirectCU II PCB design GeForce GTX 580 and -570 graphics cards. It is a high flow water block design that can be easily used with systems using weaker water pumps.

Base is made of electroless nickel plated (EN) electrolytic copper while the top is made of quality cast acrylic material. The sealing is performed by quality rubber washers. Block is mounted with enclosed M3x4 DIN7985 screws.

Enclosed is also a GPU reinforcer bracket - a metal plate which is mounted around the GPU with M3x4 DIN7985 screws which reinforces the PCB. The result is a perfect contact between the GPU core and the water block without any unwanted bending of the circuit board.

EK also encloses two-slot I/O bracket which replaces the original three-slot, in order to make installation of mutliple graphics cards easier.

Due to the size of the circuit board, the fittings (not enclosed!) can be used only on one side of the water block.

Enclosed:
- EK-FC580 DCII series water block
- EK-FC580 DCII 2-slot I/O bracket
- GPU reinforcer
- mounting mechanism with screw-in brass standoffs
- thermal pads
