Installation and mounting manual for EK-FC 6970 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
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 1: GENERAL INFORMATION.

STEP 2: PREPARING YOUR GRAPHIC CARD.
1. REMOVING STOCK COOLER: Remove encircled
screws:
STEP 2 cont.: PREPARING YOUR GRAPHIC CARD.
1 cont.. REMOVING STOCK COOLER. Remove all encircled screws.
All heat sink
assembly screws and backplate should be removed. There are 15 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 Q-tip, 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 both GPUs
and bridge chip with electrically non-conductive thermal interface material (TIM) - for
example: Arctic Cooling MX-2™ or MX-4™ 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, 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 and 3 will have to be cut by
user to match all small power regulation 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. Brass standoffs are obligatory in order to attach
this water block to the printed circuit board of the graphics card. Please use the
encased key to screw them to the copper base of the water block.
