HEATKILLER® GPU-X²4870/4890
The HEATKILLER® GPU-X² 4870/4890 guarantees the highest degree of cooling power. The unique
design ensures maximum performance on a level with current high-end CPU coolers. Extremely fine
microstructures cool both graphic processors very effectively. All other relevant components (e.g.
RAM, NVIO, VRM) are also cooled.
The top and bottom parts consist of highly pure electrolyte copper.

Attention: Conversion at your own risk. Non-observance of the installation instructions may damage
the graphic board. Watercool will assume no liability for damage to the hardware. In case of

Dismantling the original cooler may lead to the loss of the manufacturer's warranty. In case of
uncertainty, please contact the manufacturer of the graphic board.
Preparing the graphic board
Remove the original cooling element and all remainders of the thermal pads.
Now fit each of the four M 3 x 8 screws in the GPU area with a washer and press them through the
card from the GPU area below. The red spacers are subsequently positioned from above. It is easier
to screw the screws into the spacers than to press them into them.
Then place the pre-cut pads onto the graphic board, as shown below.
Evenly apply thermal grease to the GPU area.
