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.
3A. ATTACHING BLOCK AND ASUS BACKPLATE TO GRAPHIC CARD
. By
using Philips screwdriver screw in enclosed M3 DIN7985 screws, washers and M3
nuts. EKWB recommends the following procedure:
1.
Start screwing two (2) M3x4 DIN7985 screws on the MOSFET area and
continue outwards. Use a PVC washer underneath both screws!
2.
Place the ASUS factory backplate onto the graphics card circuit board
3.
Screw in four (4) M3x4 DIN7985 screws around the GPU core and three
(3) surrounding M3x6 DIN7985 screws directly to the standoffs on the
water block.
4.
Screw in the remaining four (4) M3x8 DIN7985 screws (which go through
PCB) and secure them with M3 nuts. Use PVC washer underneath each
nut!
3B. ALTERNATIVE MOUNTING OPTION WITHOUT USING ASUS BACKPLATE.
By
using Philips screwdriver screw in nine (9) enclosed M3x4 DIN7985 screws into each and
every standoff on the water block. 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. Note the pattern of contact on a piece of paper. Then repeat
substeps in previous section to reattach the block. In case you fail to obtain good contact, please check again your thermal pad thickness or contact our support
service.
STEP 5: REPLACING THE ORIGINAL I/O BRACKET
STEP 6: FITTING POSITIONING
Remove the four (4) screws and four (4) hexagonal nuts securing the original three-
slot I/O bracket to the circuit board. Replace the original I/O bracket with enclosed EK
FC7970 DCII I/O bracket and install it using the original screws.
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-FC7970 DCII 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.
STEP 7: INSERTING CARD IN YOUR PC CASE
Carefully lift your graphics card with installed block and insert it in your PC’s motherboard PCIe expansion slot. Please bear in mind that your cards is probably heavier than when
it was equipped with original heatsink 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.
