Vector² Arc A750/A770 D-RGB

Please note the installation of the product is intended to be undertaken

by an adequately trained and experienced person. You are installing the

product at your own risk. If you are not properly trained or experienced

or feel unsure about the installation procedure, please refrain from

installing the product yourself and contact our tech support for

assistance. We disclaim our liability for any damages to the product as

well as incidental, consequential, or indirect damages incurred due to

improper or inappropriate installation.

Before you start using this product, please follow these basic guidelines:

Remove your graphics card from the computer for the safest

mounting process to prevent any possible damage to your

GPU or its circuit board (PCB).

The EK Fittings require only a small amount of force to screw

them ﬁrmly in place since the liquid seal is ensured by the

rubber O-ring gaskets.

The use of corrosion-inhibiting coolants is always

recommended for liquid cooling systems and mandatory for

nickel-plated water blocks!

Do not use pure distilled water!

For best results, EK recommends the use of EK-CryoFuel

coolants! To reach optimal performance, make sure to

thoroughly bleed the air out of your water block!

PREPARING THE GRAPHICS CARD

Phillips Head Screwdriver

REMOVING THE STOCK COOLER

Place your graphics card on the ﬂat surface and carefully remove the

stock cooler. Do not forget to unplug all the LED and fan connectors.

Pay attention to the following steps in order to install the water block

onto the graphics card

PREPARING THE WATER BLOCK FOR INSTALLATION

STEP 1

Unscrew ﬁve (5) Screws AX1 M2.5 x 8 mm. Remove the backplate

together with the Screws and backplate standoffs. Standoffs must stay

on Screws AX1 M2.5 x 8 mm. Remove the PCB cardboard. Save the

removed parts for later steps.

Do not remove standoffs from screws! In case the

standoff detaches from the screw, replace it with a

spare one. When replacing the standoff make sure

that you screw it on the AX1 M2.5 x 8 screws. Do not

push the standoff onto the screw AX1 M2.5 x 8 mm.

STEP 1

For this step, you will need:

CUTTING AND PLACING THERMAL PADS

STEP 1

The GPU water block comes with thermal pads that have to be cut

into smaller pieces to cover all the VRM components, such as COILs,

MOSFETs, and drivers.

Remove the protective foil from both sides of the thermal

pad before installation.

Replacement thermal pads:

Thermal Pad F 1.0 mm – (120 x 16 mm) EAN: 3830046996732

Thermal Pad G 2.0 mm – (120 x 24 mm) EAN: 3830046996794

STEP 2

Once cut to the size, Thermal Pads should be placed on the PCB, as

shown in the picture.

Thermal Grease

STEP 1

Apply the enclosed thermal grease (thermal compound) on the

GPU heat spreader – IHS – as shown in the image. The layer of the

thermal compound must be thin and even over the entire surface

of the IHS.

The excessive or uneven application of thermal grease

may lead to poor performance!

APPLYING THERMAL COMPOUND

For this step, you will need:

ATTACHING THE WATER BLOCK

STEP 1

Carefully position the water block with preinstalled standoffs on the

graphics card. During this process, make sure you have aligned the

mounting holes of the PCB with the holes of the water block.

Pay attention not to use too much force when pressing

the block down to the PCB since chip dies are prone

to cracking.

Before attaching the PCB to the Water Block, make sure

all the Thermal Pads are placed correctly!

STEP 1

- 10 -

STEP 2

Use eight (8) M2.5 x 4 AX1 Screws and PVC washers to tighten

the PCB on the water block. Tighten the screws evenly using the

Phillips-head screwdriver. EK recommends you start tightening the

screws around the GPU core ﬁrst, and then continuing outward to

prevent damage to the GPU.

Screws must be present in the places marked on the picture.

For this step, you will need:

Polyamide Washer

(8 pcs)

M2.5 x 4 AX1

Screw (8 pcs)

Phillips Head

Screwdriver
