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 to PCB. Chip dies
are prone to cracking.
3. ATTACHING BLOCK TO GRAPHIC CARD
. By using Philips screwdriver 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!
STEP 4: CHECKING FOR CONTACTS
Temporarily remove 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: SECURING I/O BRACKET
STEP 6: FITTING POSITIONING
Use one M3x6 screw, one PVC washer and one M3 nut to secure the I/O (also known
as PCI) bracket firmly to the circuit board. This will allow the computer chassis to carry
the weight of the water block thus reducing the tension to the PCI-express slot.
Tighten the screw with Philips head screwdriver while holding the M3 nut with your
thumbs firmly.
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-FC680 GTX FTW 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.
INSTALLING EK-FC LINK:
Alternatively you can install the enclosed EK-FC Link which allows installation of both
EK-FC Bridge 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 DIN7985 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 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.
