USER GUIDE
GPU WATER BLOCK
EK-Pro
RTX A5000

If this product is made from aluminum and can be only used
with other aluminum liquid cooling components, such as Al
fittings, water blocks and radiators. Mixing aluminum with
copper and brass products can cause galvanic corrosion of
the metal and render liquid cooling equipment useless. Such
misuse is not covered by warranty.
Before you start using this product, please follow these basic guidelines:
Please carefully read the manual before beginning with the
installation process!
Please remove your graphics card from the computer to
assure safest mounting process in order to prevent any
possible damages to your GPU and/or graphics card 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!
Make sure to thoroughly bleed air out of your water block, or
you will not reach optimal performance!

PREPARING THE GRAPHICS CARD
CLEANING THE PCB
Place your graphics card on the flat surface and carefully remove
the stock cooler. Do not forget to unplug all fan connectors. Pay
attention to the following steps when installing the EK-RTX A5000
water block onto your graphics card.
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. After that,
remove all remaining stock thermal pads from the PCB.
NONABRASIVE
CLOTH
STEP 1
Your 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.
You must remove the protective foil from both sides of the
thermal pad before installation.

STEP 2
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.

STEP 1
Apply the enclosed EK-TIM Ectotherm 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
STEP 1
Thermal Grease
For this Step, you will need:

- 9 -
Phillips Head
Screwdriver
After unboxing the preinstalled water block, carefully put it on soft
surface. Untighten four (4) screws AX1 M2.5 x 7 and remove foam
and RTX A5000 Backplate. Four (4) screws AX1 M2.5 x 7 and foam
you will not need any more.
UNPACKING AND REASSEMBLYING
For this Step, you will need:
FOAM
SCREW AX1 M2.5 x 7 (4x)
RTX A5000 BACKPLATE

- 10 -
This procedure is the same for all full-cover water blocks.
STEP 1
MOUNTING PCB ON THE WATER BLOCK
Firstly, stick three (3) Washer POLYAMID M2.5 0.7 mm selfglued, on
the top of 3 the biggest standoffs.
Carefully position the graphic card on water block with preinstalled
standoffs. During this process, make sure you have aligned mounting
holes of the PCB with holes of the water block.
Unscrew two (2) preinstalled M3 x 6 DIN7991 screws to properly
place the PCB power connector in power adapter. After placement
is done, tighten them on place again.
Pay attention not to use too much force when pressing
the PCB down to the block since chip dies are prone to
cracking.
Tighten four (4) screws AX1 M2.5 x 4 with belonging four (4) Washers
M2.5 x 0.5 as shown in the picture. Tighten the screws evenly using
the Phillips head screwdriver.
For this step you will need Standard mounting kit 2.
