2. ATTACHING 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. By using Philips head screwdriver screw in 6 (six) enclosed M3x4 DIN7985
screws (see picture below for reference). Make sure there is original self-adhesive
plastic washer underneath each screw. Do not attempt to install the water block without
the washers.
2. cont
. By using enclosed Allen key 2mm screw in 4 (four) enclosed M3x9 DIN7991
screws. By using Philips head screwdriver secure the backplate using 2 (two) enclosed
M3x4 DIN7985 screws.
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 cirucit. 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 at http://www.ekwb.com/support.
STEP 5a: REPLACING THE ORIGINAL I/O BRACKET
STEP 6: INSTALLATION OF FITTINGS AND TUBING
Remove two hexagonal nuts securing the original two-slot I/O bracket to the
circuit board. Replace the original I/O bracket with enclosed EK-FC7990 two-slot
I/O bracket and install it using 4 (four) original hexagonal nuts. Secure both
bracket tabs using M3x4 DIN7985 screw.
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-FC7990 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 5mm please use the enclosed 1.8mm nickel plated distancer! 5mm is the maximum
allowed G1/4” thread length!
In order to move the ‘Turbo’ button from the original, three-slot I/O bracket to
the EK provided two-slot I/O bracket take the following steps:
1.
release the latch on the Turbo button and slide the button through the
opening.
2.
Remove the wires from the 5-pin connector. Use a needle (or equivalent)
to release the latch (see sample photo below).
3.
Slide the button and it’s cable through
the opening in the original I/O bracket
and reinsert in the EK provided two-slot
I/O bracket. Make sure to remember pin
position!
4.
Reinstall the cable pins to the 5-pin
connector. Install the connector to the
circuit board to complete installation.
STEP 6: FINISHING INSTALLATION - INSERTING THE GRAPHICS CARD IN YOUR PC CHASSIS
At this point you may 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.
