Special water block was designed for hard enthusiast users to get the most out of newest Sapphire Radeon 4890 Vapor-X graphic card. The graphic card has extreme overclocking potential, which can be only achieved with the best cooling.
The crucial part are power reguator chips (VRC/mosfets), that are the source for extreme overclocking. Therefore EK developed full copper base to supply maximal cooling for all chips that needs to be cooled.
Top is made of quality acrylic glass. The sealing is preformed by quality rubber washer (o-ring). Block is mounted with enclosed M3x8mm screws. Standoffs for safe mounting are enclosed.

Mounting mechanism is enclosed with 2 plugs are enclosed!

Fittings can be used on both side of the block (up and down),

This is a NON Reference Design Block!

Fittings are NOT included and are optional below!

Compatibility

• Real high flow internal design gives minimum flow restriction which allows lowest possible temperatures, not only at VGA water block, but also in the entire water-cooling system.
• Cools GPU, VREG, I/O CHIPs and MEMORY modules.
• Multiple barb/fitting position allows 4 different fitting configurations.
• Allows maximum flexibility for water cooling system setup also in CF.
• Reduces temperatures up to 50°C or more at maximum load.
• Much cooler components, allow maximum possible overclocking.
• Featuring a unique, modern look copper design High performance VGA water block for Radeon HD5870 reference design series graphic cards.
• EK FC series water blocks cover all chips on graphic cards that require cooling if overclocked.
• An extreme high flow path design and unique increased cooling surface over GPU keeps all your graphic cards components cool even at highest graphical loads and over clock.
• Blocks base is made of 99,99% electrolytic copper.
• High quality CNC manufacturing.
• Leak tested to 2 bar pressure (30psi).
• Safe, noob-proof mounting system with Standoffs.
