2. PLACING THE BLOCK ON TO THE GRAPHICS CARD
. Carefully position the water
block with preinstalled 2.5 mm standoffs on to the graphics card. During this process
please make sure you align mounting holes on the PCB with holes on the water block
(same applies for other tops). Also pay attention not to use too much force by pressing
the block down to the PCB. Chip dies are prone to cracking.
3. ATTACHING THE BLOCK TO THE GRAPHIC CARD
. Use a Philips screwdriver
screw with the enclosed M3x4 DIN 7985 screws. EKWB recommends users to start
tightening the screws around the GPU core and continue outwards.
Always use a
plastic washer under each and every screw!
STEP 4: CHECKING FOR CONTACTS
If necessary 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 intended integrated circuit. Then repeat sub-steps in previous section to re-attach the block.
In case you
fail to obtain good contact, please check again that your thermal pad thickness or contact our support service at http://www.ekwb.com/support.
STEP 5: SECURING I/O BRACKET
STEP 6: INSTALLATION OF FITTINGS AND TUBING
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 the Philips head screwdriver while
holding the M3 nut with your thumbs firmly.
Screw in the two G1/4 threaded male fittings. Attach the liquid cooling tubes and connect
the water-block(s) into the cooling circuit.
EKWB recommends using EK-PSC fittings
with the EK-FC 780 GTX Classy 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.
CAUTION:
In case of using connectors other than EK-PSC series compression fittings, take
special attention to the length of the fittings’ male G1/4” thread. In case the thread is longer
than 5 mm please use the enclosed 1.8 mm nickel plated spacer!
5mm is the maximum allowed G1/4” thread length!
STEP 7: INSERTING THE 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.
