Cooler Master Eisberg 120L Prestige Liquid Cooler Review

The provided fans are relatively plain looking and use 3 pin connections. This lack of PWM support is slightly disappointing but the provided adapter does support three 3 pin devices at reasonable speeds (5v for the pump and 2 X 7 volts for the fans or if you want 12 volts plug them directly into motherboard CPU headers).

On the rear we can see the cables are black all the way up to the motor which is always nice to see. It suggests attention to detail. These fans use a rifle bearing.

The fans use a standard 25mm thickness.

As far as I can tell the Cooler Master Eisberg 120L Prestige is based off the Alphacool ST30 except it doesn’t feature the Alphacool branding on it.

Here is a close up on the radiator fins, you can’t really see that they are copper but trust me they are!

The tubing is is flexible plastic and features a coiled plastic around it which prevents the tubes getting tangled or kinking.

The radiator is exactly 30mm thick just like the Alphacool ST30.

The Cooler Master Eisberg 120L is expandable as mentioned and it uses G 1/4 inch fittings to allow you to easily add other things in.

The pump unit includes the reservoir and is a unit made especially for Cooler Master and comes emblazoned with the Cooler Master Eisberg logos.

You can see the unit is actually quite tall given the rather skinny Asetek ones we are used to seeing.

The pump unit features a small acrylic window where you can see the internals of the pump in action.

The base is fully copper and is very smooth and flat.
