## Long description

The Alphacool 11687 refill kit supplies everything required to fill an Eisbaer CPU water-cooling loop. Designed by Alphacool for use with Eisbaer series all-in-one water cooling units, the kit includes a funnel with a G1/4" thread, a syringe of thermal paste, a pump adapter cable (SATA to 3-pin) and an ATX jumper plug to power the pump externally during filling.
Advantages
The refill kit is compact and contains tools tailored for safe and controlled filling of an Eisbaer unit. The G1/4" threaded funnel fits common fill ports, the included thermal paste ensures proper CPU contact when reassembling, and the adapter cable together with the ATX jumper plug lets you run the pump without the mainboard connected. Instructions describe how to avoid running the pump dry and how to expel trapped air.
Suitable for
Refilling Alphacool Eisbaer CPU water-cooling systems
Maintenance and topping up of custom loop and AIO Eisbaer units
Situations requiring external powering of the pump during bleeding and filling
Key specifications
Brand: Alphacool
Model / MPN: 11687
EAN: 4250197116879
Funnel thread: G1/4"
Included items: threaded funnel, thermal paste syringe, SATA to 3-pin pump adapter cable, ATX jumper plug
How to use
Power off the computer and remove the Eisbaer unit. Unplug the 24-pin ATX connector from the motherboard and attach the supplied ATX jumper plug to the power supply. Place the radiator on a stable surface and set the Eisbaer CPU/pump/reservoir assembly on a slightly elevated platform. Screw the G1/4" funnel onto the fill port, connect the pump to the power supply using the SATA to 3-pin adapter, and slowly fill the reservoir until it is nearly full. Switch the power supply on via the ATX jumper to run the pump; stop the pump occasionally while filling to avoid running it dry. Once filled, close the fill port, run the unit outside the case while gently moving it so trapped air can rise into the reservoir, and top up as needed. Aim for approximately 90% reservoir fill at the end of the procedure.
Usage recommendations
Always ensure the pump does not run dry and keep the radiator positioned lower than the reservoir during bleeding to help air escape upward. Follow ESD and safety precautions when disconnecting and reconnecting the 24-pin ATX connector.
