Installation of the cooler
Then place the cooler onto the prepared graphic board and turn it over, including the board. Screw the
screws in the GPU area in slightly – crosswise and uniformly.
PLEASE NOTE: Do not tighten screws yet!
Now screw the two M3 x 5 mm screws into the cooler, in the area of the voltage converters, using one
washer each. Do not tighten these screws either.
Once all screws of the cooler have been positioned, these can be tightened slightly. To do this,
carefully tighten the screws in the GPU area crosswise. Then tighten the screws in the voltage
converter and NVIO areas slightly.
Installation and leak test
After the installation, a check and test run must be performed! The coolers are constructed on the
reference design; still, all sections of the board have to be checked for possible contact to the cooler.
In addition, the contact of the GPU to the cooler must be checked along with the bending of the board.
A slight bending of the board is normal.
A leak test should preferably be performed outside of the computer. If this is not possible, the
hardware may not be turned on during the test run!
Once all of the cooler elements were tested, the computer can be put into operation. Check the
temperature of the GPU immediately after the start!
General information
The HEATKILLER® GPU-X² 4870/4890 has a defined input/output. The port on the left (pointing
towards the slot cover) is the input. The output is located on the right, and the connections can be
installed either on the top or the bottom.
We recommend using demineralised or deionised water (distilled water) as cooling medium. To
prevent the build-up of algae, use common citric acid, which reliably prevents the spread of algae.
