Installation and mounting manual for EK-FC DCII water 780 GTX Ti

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 for updates. Before www.ekwb.com

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 Ti 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 screws securing it to the board. Wipe off the all

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 78 GTX Ti DCII series water block. 0

1: Thermal pad D –0.5mm

(for memory IC):

2: Thermal pad B – 0.5mm

(for VRM/MOSFET):

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 Philips screwdriver a

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: INSTALLATION OF FITTINGS AND TUBING

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 blocksTi . 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 6: 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.
