Installation and mounting manual for EK-FC 780 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 GeForce 780 GTX DCII series graphics card.
STEP 2: PREPARING YOUR GRAPHIC CARD.
1. REMOVING STOCK COOLER: Remove encircled screw on the
bracket (required only on certain models):
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.
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 q-tip
, 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.
Wipe off the
remains (by using non–abrasive cloth or
q-tip ) of the
original thermal compound until the components and
circuit board are completely clean. Apply thermal
compound: lightly coat
NVIDIA GPU chip with enclosed
EK-TIM Ectotherm 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 D – 0.5mm (RAM 8x), Thermal Pad B – 0.5mm (75x50mm)
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: EK-TIM Ectotherm, 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-FC 780 GTX DCII series water block.

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

2. PLACING THE BLOCK ON TO THE GRAPHICS CARD
. Carefully position the water
block with preinstalled 2.5 mm standoffs on to the graphics card. During this process
please make sure you align mounting holes on the PCB with holes on the water block
(same applies for other tops). Also pay attention not to use too much force by pressing
the block down to the PCB. Chip dies are prone to cracking.
3. ATTACHING THE BLOCK TO THE GRAPHIC CARD
. Use a Philips screwdriver
screw with the enclosed M3x4 DIN 7985 screws. EKWB recommends users to start
tightening the screws around the GPU core and continue outwards.
STEP 4: CHECKING FOR CONTACTS
If necessary temporarily r emove the water block to check for uniform surface contact between the block and the components, pay special attention to the VRM section of the
graphics card. Check whether the water block makes contact with the intended integrated circuit. Then repeat sub-steps in previous section to re-attach the block. In case you
fail to obtain good contact, please check again that your thermal pad thickness or contact our support service at http://www.ekwb.com/support.
STEP 5: SECURING I/O BRACKET
STEP 6: INSTALLATION OF FITTINGS AND TUBING
Use one M3x6 screw, one PVC washer and one M3 nut to secure the I/O (also
known as PCI) bracket firmly to the circuit board (This may vary from model to
model). This will allow the computer chassis to carry the weight of the water
block thus reducing the tension to the PCI-express slot. Tighten the screw with
the Philips head screwdriver while holding the M3 nut with your thumbs firmly.
Screw in the two G1/4 threaded male fittings. Attach the liquid cooling tubes and connect
the water-block(s) into the cooling circuit. EKWB recommends using EK-PSC fittings
with the EK-FC 780 GTX DCII series water blocks. To ensure that the tubes are
securely attached to the barb/fittings, please use hose clamps or an appropriate substitute.
You can use any opening as an inlet/outlet port.
CAUTION: In case of using connectors other than EK-PSC series compression fittings, take
special attention to the length of the fittings’ male G1/4” thread. In case the thread is longer
than 5 mm please use the enclosed 1.8 mm nickel plated spacer!
5mm is the maximum allowed G1/4” thread length!
STEP 7: INSERTING THE CARD IN YOUR PC CASE
Carefully lift your graphics card with installed block and insert it in your PC’s
motherboard PCI-express expansion slot. Please bear in mind that your graphics
card is probably heavier than when it was equipped with original heat sink fan
assembly. One needs to be very careful when handling the graphics card. Avoid
all un-needed manipulation of the VGA/water block assembly that might damage
your card or water block during final installation.
