Installation and mounting manual for EK-FC7850 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.ekwb.com for updates. Before
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. 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.
3. This water block is compatible with CSQ series EK-FC Bridge only!
4. The use of quality, market proved corrosion inhibiting coolants is always strongly recommended for any liquid cooling system.
STEP 1: GENERAL INFORMATION. Sample picture of AMD Radeon HD 7850 graphics card (PCB 109-C40337-00)
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 factory heat-sink fan solution to the printed circuit board.
There are up 9 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 recommends the
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 ™,MX-4 ™ or GELID GC-Extreme ™
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 @ EKWB web shop: Thermal Pad A –1mm (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 “2”) in order to even
further improve the thermal performance of the EK-FC7850 series water block.

2. PLACING BLOCK TO GRAPHIC CARD. Carefully position the water block with
preinstalled 2.5mm standoffs on to the graphics card. During this process please make
sure you align mounting holes on PCB with holes on the water block. Also pay attention
not to use too much force by pressing block down onto PCB. Chip dies are prone to
cracking.
3. ATTACHING BLOCK TO GRAPHIC CARD. By using Philips screwdriver gently
screw in enclosed M3x4 DIN7985 screws. EKWB recommends start screwing the
screws around the GPU core and continue outwards. Always use a PVC washer under
each and every screw –use EK provided washers only when your card has no washers
by default!
STEP 4: CHECKING FOR CONTACTS
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 VRM. Then repeat sub-steps in previous section to re-attach the block. In case you fail to obtain good contact,
please check again your thermal pad thickness or contact our support service.
STEP 5: FITTING POSITIONING
STEP 6: INSTALLING EK-FC LINK
Screw in the fittings in the G1/4 threaded openings on plastic top of the water block.
EKWB recommends using EK-PSC fittings with the EK-FC7850 series water blocks. 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.

Alternatively you can install the enclosed EK-FC Link which allows installation of both
EK-FC Bridge CSQ system as well as the use of G1/4 threaded fittings.
Please remove the middle M4x8 DIN7984 screw, install the EK-FC Link together with
OR 14x1.5mm gaskets and secure it with enclosed M4x25 DIN7984 screw. Use
enclosed 2.5mm Allen (hex) key!
Once installed you can install two (preferably angled) G1/4 threaded fittings or any EK-
FC Bridge CSQ series interconnect ( serial or parallel )
STEP 7: INSERTING CARD IN YOUR PC CASE
Carefully lift your graphics card with installed block, inspect visually for any unwanted contacts that may cause shorting out 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.
REQUIRED TOOLS AND ACCESSORIES:
scissors philips screwdriver thermal grease
Use 5 enclosed PVC washers
underneath each screw! In
case the card is already
equipped with washers you
may reuse the original
washers!
