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.
Also pay attention not to use too much force by pressing the block down to the PCB.
Chip dies are prone to cracking.
3a. ATTACHING THE BLOCK AND MSI BACKPLATE TO GRAPHIC CARD
. By
using Philips screwdriver screw in enclosed M3x4, M3x6 DIN7985 screws and washers.
EKWB recommends the following procedure:
1.
Screw in four (4) M3x4 DIN7985 screws around the GPU core. Do not tighten
the screws firmly just yet.
2.
Start screwing eight (8) M3x6 DIN7985 screws to secure the backplate to the
water block.
3.
Once all twelve (12) screws are in position tighten the screws completely.
Please note:
You may need to widen (re-drill) the holes on
the backplate to 3mm using electric power drill in order to
re-use the backplate!
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 3b:ATTACHING THE WATER BLOCK (W/O the Backplate)
STEP 5: INSTALLATION OF FITTINGS AND TUBING
Gently fasten M3x6 DIN7985 screws into pre-installed standoffs. There is no need
to use excessive force on screws as you may over-tighten them and make
damage to standoff/screw connection.
When reinserting MSI’s GPU reactor, be careful to precisely reattach PCB and not
force it downwards as you may bend the connection pins. Re-insert the lid to
finish installation.
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-CSQ fittings
with the EK-FC 780 GTX Lightning 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-CSQ 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 5: 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.
