Installation and mounting manual for EK-FC7970 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.ekwaterblocks.com for updates.
Before installation of this product please read important notice, disclosure and warranty conditions printed on the back of the box or our home page.
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. The use of an algaecide and corrosion inhibitors is always recommended for any liquid cooling system.
STEP 1: GENERAL INFORMATION.

STEP 2: PREPARING YOUR GRAPHIC CARD.
1. REMOVING STOCK COOLER: Remove four encircled
screws on the bracket:
STEP 2 cont.: PREPARING YOUR GRAPHIC CARD
1 cont.. REMOVING STOCK COOLER. Remove all encircled screws. All heat sink assembly
screws should be removed. There are 11 screws on the back of the graphic 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 recommend
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 ™ 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, 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: 1x Thermal Pad B – 0.5mm (75x50mm), Thermal Pad A – 0.5mm (100x16mm).
STEP 3: INSTALLING 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-FC7970 DCII series water block.
