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-FC1080 GTX 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 performance allowing this product to be used in liquid cooling systems using weaker water pumps. The base is made of electrolytic copper while the top is made of quality acrylic material. The top also features two pre-drilled slots for 3mm LED diodes. The sealing is ensured by quality rubber washers. Screw-in brass standoffs are pre-installed and allow for a safe and painless installation procedure. EK Water Blocks recommends the purchase of aesthetic retention backplate (EK-FC1080 GTX Backplate – Black, Nickel, Blue, Red, Gold) which improves the looks of your graphics cards and also provide some passive cooling to the circuit board VRM section. G1/4″ threaded fittings can be used on both sides of the FC Terminal. Up to four EK-FC1080 GTX 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.
