Installation and mounting manual for EK-FC 5870 V2 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
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 1: GENERAL INFORMATION. Sample picture of RADEON HD 5870 V2 graphic card.
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 6 to 8 screws on the back
of the graphic card. Some brands may have plastic attachments of mosfet heat sink (see
dashed encircled screws)
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 the GPU with for example Arctic Cooling MX2 ™ or
MX3 ™ thermal compound. Follow this link:
cooling.com/catalog/images/install_mx2_retail.pdf
for detailed
instructions. 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.) All thermal pads
are 1mm thick. Thermal pads #1 need to be cut to 4 pieces for RAM modules.
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. 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.
2. PLACING STANDOFFS ON BLOCK. Standoffs are obligatory to make this
block fully functional and safe mounting. 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.
