This product is compatible with Nvidia Quadro RTX 4000 graphics card.
It is intended for installation by expert users only. Please consult with a
qualified technician since improper installation may result in damage
to the equipment. EK assumes no liability whatsoever, expressed
or implied, for the use of these products, nor their installation. The
following instructions are subject to change without notice. Please visit
our website at www.ekwb.com for updates. Before the installation of
this product, please read important notice, disclosure, and warranty
conditions printed on the back of the box.
Before you start using this product, please follow these basic guidelines:
Carefully read the manual before beginning with the
installation process.
Remove your graphics card from the computer for the safest
mounting process and to prevent any possible damages to your
GPU or its circuit board (PCB).
EK Fittings require only a small amount of force to screw them
firmly in place since the liquid seal is ensured with the rubber
O-ring gaskets.
The use of quality market-proven corrosion-inhibiting coolants
is always strongly recommended for any liquid cooling system.
Do not use pure distilled water as a cooling liquid! For best
results, EK recommends the use of EK-CryoFuel Coolants.

PREPARING THE GRAPHICS CARD
STEP 1
REMOVING THE STOCK COOLER
Remove all encircled screws using a Phillips head screwdriver. All heat
sink assembly screws should be removed, including self-adhesive
washers on both sides of the PCB (if present). After that, remove the
I/O bracket.
STEP 2
CLEANING THE PCB
Carefully detach the original stock cooler after removing all screws
that are securing it to the board. Wipe off the remains of the original
thermal compound using a nonabrasive cloth or Q-tip, as shown
in the sample image, until the components and circuit board are
completely clean. EK recommends the use of denatured alcohol for
removing TIM leftovers.

STEP 3
APPLYING THERMAL COMPOUND
Lightly coat the GPU chip with enclosed EK-TIM Ectotherm thermal
grease. For best performance, EK recommends applying thermal
grease in the form of a cross (see sample image).

CUTTING THERMAL PADS
Your GPU water block comes with thermal pads that have to be cut into
smaller pieces to cover all the VRM components. You must remove the
protective foil from both sides of the thermal pad before installation.
Replacement thermal pads:
1. Thermal Pad F 1.0mm – (120x16mm) – (EAN: 3830046996732)
2. Thermal Pad F 0.5mm – (120x16mm) – (EAN: 3830046996725)
STEP 5
PLACING THERMAL PADS ON PCB
Once cut to size, thermal pads should be placed on the PCB, as illustrated
below. EK made sure to provide you with more than an adequate quantity
of thermal pads to complete this Step.

INSTALLING THE WATER BLOCK
STEP 1
PLACING THE BLOCK ON THE GRAPHICS CARD
Carefully position the water block with preinstalled standoffs on
the graphics card. During this process, please make sure you have
aligned mounting holes on the PCB with holes on the water block
(same applies to other tops).
Pay attention not to use too much force when pressing the block
down to the PCB since chip dies are prone to cracking.

STEP 2
ATTACHING THE BLOCK TO THE GRAPHICS CARD
Use a Phillips head screwdriver with the enclosed M2.5X4 and
M2.5X6 screws. EK recommends you start tightening the screws
evenly, around the GPU core first, and then continuing outward to
prevent the damage to the GPU. Always use a plastic washer under
each screw!

STEP 4
INSTALLATION OF FITTINGS AND TUBING
Screw-in two (2) G1/4 threaded male fittings. Attach the liquid
cooling tubes and connect the water block(s) to the cooling loop.
EK recommends using EK-Fittings with this water block.
You can use any opening as an inlet/outlet port.
Do not forget to plug the remaining two openings with enclosed
EK-Plug G1/4 or its equivalent.
CAUTION: In case of using connectors other than EK Compression
Fittings, pay special attention to the length of the fittings’ male G1/4”
thread. 5mm is the maximum G1/4” thread length allowed!
STEP 3
CHECKING FOR CONTACT
If necessary, temporarily remove the water block to check for uniform
surface contact between the block and 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 Steps from the previous section to re-attach the block.
In case you fail to obtain good contact, please check again or
contact our support service at www.ekwb.com/support.

STEP 5
INSERTING THE GRAPHICS CARD IN THE PC CASE
Carefully lift your graphics card with the installed water block and
insert it into your PC’s motherboard PCIexpress expansion slot.
Please bear in mind that your graphics card is very likely heavier than
before it was equipped with the water block.
You need to be very careful when handling the graphics card.
Avoid all unnecessary manipulation of the VGA-water block
assembly that might damage your card or water block.
