Installation and mounting manual for EK-FC680 GTX DCII water block
This product is intended for installation only by expert users. Please consult with a qualified technician for installation. Improper installation may result in damage to your equipment. EK Water Blocks assumes no liability
whatsoever, expressed or implied, for the use of these products, nor their installation. The following instructions are subject to change without notice. Please visit our web site at www.ekwb.com for updates. Before
installation of this product please read important notice, disclosure and warranty conditions printed on the back of the box.
Before you start using this product please follow these basic guidelines:
1. Please carefully read the manual before through before beginning with the installation process!
2. Please remove your motherboard from the computer to assure safest mounting process in order to prevent any possible damages to your CPU and/or motherboard’s circuit board (PCB).
3. The EK High Flow and EK-PSC type fittings require only a small amount of force to screw them firmly in place since the liquid seal is ensured by the rubber o-ring gaskets.
4. The use of corrosion inhibiting coolants is always recommended for any liquid cooling system.
STEP 1: GENERAL INFORMATION. Sample picture of nVidia GeForce GTX 680 (NVA P2002 equivalent)
STEP 2: PREPARING YOUR GRAPHIC CARD.
1.REMOVING STOCK COOLER / BACKPLATE ASSEMBLY: Remove
four encircled screw on the back side of the graphics card:
STEP 2 cont.: PREPARING YOUR GRAPHIC CARD
1 cont.. REMOVING STOCK COOLER. Remove the stock GPU HSF assembly. Remove all encircled
screws attaching the backplate and VRM heatsink to the circuit board as well as two screws attaching the
I/O bracket to the HSF. There are up to 12 screws on the front of the graphics card.
2. CLEANING THE PCB. Carefully detach the original stock cooler
after removing all screws securing it to the board. Wipe off the
remains (by using non–abrasive cloth or
qtip
, as shown on sample
photo) of the original thermal compound until the components and
circuit board are completely clean. EKWB recommends the use of
denatured alcohol for removing TIM leftovers.
3. APPLYING THERMAL COMPOUND. Apply thermal
compound: lightly coat
AMD
GPU chip with for example
Arctic Cooling MX-2 ™,MX-4 ™ or GELID GC-Extreme ™
thermal grease. EKWB recommends to apply thermal
grease in cross form for best performance (see sample
picture).
4. CUTTING THERMAL PADS. Your block comes with thermal pads, some of which are already pre-cut. Others
have to be cut to smaller chunks in order to cover all the VRM components such as MOSFETs and drivers. PLEASE
REMOVE THE PROTECTIVE FOIL FROM BOTH SIDES OF THE THERMAL PADS PRIOR TO INSTALLATION.
Replacement thermal pads: Thermal Pad B –0.5mm (75x50mm), Thermal Pad A –0.5mm (100x16mm).
STEP 3: INSTALLING THE WATER BLOCK
1. PLACING THERMAL PADS ON PCB. Place thermal pads on chips so that numbers on chips match size of thermal pads. EKWB made sure users have more than
enough pads to cover all surfaces that need to be covered to make block fully functional). EKWB recommends using small drops of electrically non-conductive (for
example: Arctic Cooling MX-2 ™, MX-4 ™ or GELID GC-Extreme™) thermal grease on each phase regulator (that is being covered with thermal pad) in order to even
further improve the thermal performance of the EK-FC680 GTX series water block.

(for memory IC):
2: Thermal pad B –0.5mm
