Description

Thank you for purchasing a graphics card water block

manufactured by aqua computer. The aquagrATIx for

HD6990 has been specifically designed for graphics

cards according to reference design of the chip man-

ufacturer. The aquagrATIx for HD6990 effectively

cools the RAM, voltage regulators and GPU of your

graphics card. The base part of the water block is

manufactured from pure copper for outstanding per-

formance and durability.

Installation

Step 1:

Remove the originally installed air cooling unit from

the graphics card. The procedure necessary to per-

form this might vary slightly depending on the graph-

ics card. Use extreme caution not to damage any of

the highly sensitive components of the graphics card!

Remove the screws holding the air cooling unit (see

red marks in the figure) and lift the air cooling unit off

the graphics card while disconnecting the fan con-

nector.

Step 2:

Remove all thermally conductive pads from the graph-

ics card and clean all surfaces with direct contact to

the cooling unit from remaining thermal compounds

using benzine if necessary.

Apply a thin layer of thermal compound to the GPU

and the RAM modules (indicated by red marks in the

figure). The thermal compound must not be electric-

ally conductive! Cut fitting pieces from the thermal

pad supplied with the water block and place them on

top of the voltage regulators and the bridge chip (in-

dicated by green marks in the figure).

Step 3:

Attach the aquagrATIx for HD6990 to the graphics

card. The backplates of the air cooling unit are being

the four screws adjacent to the GPU, afterwards the

remaining screws:

Four screws M3x4 mm, green marks in the figure.

Four screws M3x6 mm, blue marks in the figure.

Seven screws M3x8 mm with countersunk head, red

marks in the figure, three of them fixated with hex nuts

on top of the PCB.

Step 4:

Carefully check that the water block has level contact

to all relevant components of the graphics card. Do

not put the graphics card to work if the cooler does

not perfectly fit the graphics card! In this case, disas-

semble and repeat the mounting procedure. All

screws must not be overly tightened to prevent the

PCBs from twisting!

Step 5:

Insert the graphics card to your PC and integrate the

water block into your cooling system. Be sure not to

connect any water blocks in parallel but only consec-

utively. A detailed instruction on building a water

cooling system and plug&cool connectors as well can

be found on our website

www.aqua-computer.de

please check the section support/download.

Step 6:

Put the water cooling system into operation, but do

not connect any other PC components to the mains

supply! Check the water block as well as the fittings

for leakages and do not put your PC into operation

unless you can definitively eliminate the possibility of

coolant leaking from the system! If any component

has been in contact with coolant, do not put it into

operation before it is completely dry again! For oper-

ating the graphics card, the water block must be cor-

rectly mounted and be connected to a water cooling

system featuring adequate cooling performance! For

corrosion inhibition, "Double Protect Ultra" or a mix-

ture of water and ACfluid according to the prepara-

tion instructions provided with ACfluid must be used

as coolant!
