This includes a funnel with G1/4" thread, a high-quality thermal paste in a syringe, an adapter cable for the pump and an ATX jumper plug.\nEasy to use\nDisconnect the Eisbaer from your system and turn off the power supply. Then unplug the 24-pin ATX connector from the motherboard and mount the ATX jumper plug to it. Place the radiator on a table and the cooler-AGB unit on a slightly elevated spot. You then simply mount the funnel on the fillport. Using the SATA to 3-pin adapter cable, you can now connect the Eisbaer's pump to your power supply. Now slowly fill the Eisbaer with your liquid until the expansion tank is full. Now you can switch on the power supply again. Through the ATX jumper plug, the power supply will start and the Eisbaer's pump will begin to work. It is important that you switch off the pump in between to refill liquid again. The pump must never run dry.\n\When the Eisbaer is filled, you can close the fill port again. Then let the Eisbaer run outside your enclosure for a bit while you shake the Eisbaer in all directions. Ideally, you should always keep the radiator lower than the radiator-AGB unit while doing this, so that the air can move up into the expansion tank. You may find that you need to add some more fluid if necessary. The expansion tank should be filled to about 90% at the end of the entire procedure.
