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.ekwaterblocks.com for updates.
Before installation of this product please read important notice, disclosure and warranty conditions printed on the back of the box.
The barb hose fittings require only a small amount of force to screw them in; otherwise the high flow fittings might break. These fittings do not need to be tightened with much force because the
liquid seal is made using o-rings.

STEP 2: PREPARING YOUR GRAPHIC CARD.
1.REMOVING STOCK COOLER. Remove all encircled screws. All heat sink
assembly screws should be removed. There are 12 screws on the back of the graphic
card.
2.CLEANING THE PCB. Carefully detach the original heat sink after removing all
fasteners securing it to the board and bracket. 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 does not
recommend using any liquids for removing paste.
3.APPLYING THERMAL COMPOUND
Apply thermal compound: lightly coat the GPU with for example Céramique™ thermal
compound. Follow this link http://www.arctic-
cooling.com/catalog/product_info.php?cPath=39_&mID=127&language=en for
detailed instructions. EKWB recommends non-conductive MX-2, which should be
applied in cross form for best performance (see sample picture).
4.CUTTING THERMAL PADS. Your block comes with thermal pads, which have to
be placed on chips (PLEASE REMOVE FOIL ON BOTH SIDES OF THERMAL PADS
PRIOR TO INSTALLATION. WARNING: DIMENSION BELLOW ARE SCALED)
5.PLACING THERMAL PADS ON PCB. Place thermal pads on chips so that
numbers on chips match size of thermal pads. Thermal pad number 2 will have
to be cut by user to match all small mosfet chips (EKWB made sure users have
more than enough pads to cover all surfaces that need to be covered to make
block fully function). You can also use small drop of thermal grease on chips to
make thermal pads more adhesive.
6.PLACING STANDOFFS ON BLOCK. Standoffs are obligatory to make this block
fully functional. Please use small amount of thermal grease on standoffs and
glue them so they are concentric with mounting holes. Once they are stuck to
block be careful not to move them.

7. PLACING BLOCK TO GRAPHIC CARD. During this process please make sure you align
holes on PCB with holes on block. Also pay attention not to use too much force by
pressing block down to PCB. Chips are prone to cracking.
8. ATTACHING BLOCK TO GRAPHIC CARD. By using Philips screwdriver screw in
enclosed M3x8 screws. EKWB recommends starting around the GPU core and continue
outwards.
STEP 3: CHECKING FOR CONTACTS
Temporarily r emove the water blocks to check for uniform surface contact between the block and the components. Note the pattern of contact on a piece of paper. Then repeat
steps 5 and 8 to reattach the block applying more or less pressure to the areas where you have found it necessary.
STEP 4: POSITIONING FITTINGS AND CONNECTING TO WATER CIRCUIT
Please use spacer on copper base (see picture). Screw in the fittings and plugs, attach the liquid cooling tubes and connect the water-block(s) into the cooling circuit. EKWB
recommends using high flow fittings with the EK-FC 4890 VAPOR X series water blocks. To ensure that the tubes are securely attached to the barb/fittings, please use hose
clamps or an appropriate substitute. The use of an algaecide is always recommended for any liquid cooling system.
You can use any hole as an inlet/outlet hole.
