EK-FC R9-285 is a high performance full-cover water block for AMD reference design Radeon R9 285 and -380 series graphics card. Please check our Cooling Configurator online compatibility system for detailed compatibility list!
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-FC R9-285 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. Moreover, such design offers great hydraulic perfromance allowing this product to be used in liquid cooling systems using weaker water pumps.

Base is made of nickel-plated electrolytic copper while the top is made of quality acrylic glass 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-FC R9-285 Backplate - Black) which improves the looks of your graphics cards and also provide some passive cooling to the VRM section.
G1/4" threaded fittings can be used on both sides of the FC terminal. Flow orientation doesn't matter and is thus not prescribed.
Up to four EK-FC R9-285 water blocks can be used on a single ATX form factor motherboard by using EK-FC Terminal (DUAL, TRIPLE or QUAD type) system or other means of interconnectivity. Please note that EK-FC Bridge & Link system is not compatible with this water block.
