Cooler Master Eisberg Prestige 240L Review

It’s clear from looking briefly over the Eisberg 240L that it is cut from a different crop to the other 240 mm water cooling units we’ve reviewed previously.  There are so many subtle differences here and there which we will now describe in more detail.

The CPU block could hardly be described as low profile and is very sizeable indeed compared to that of the Seidon 240M.  However, it contains a much beefier pump alongside small reservoir and a fill port.  Unlike any of the other units on the market, the Eisberg 240L has been designed so that users can extend the loop should they wish.  Cooler Master has used standard compression fittings throughout the loop to facilitate this.

Turning the CPU block, over reveals the cold plate which is made from 100% copper to aid heat flow.  It has a smooth finish and is secured in each corner with a regular screw.

There is also a small window in the side of the CPU block which lets you see the liquid inside the reservoir.

The pump is powered by a standard 3-pin fan header.  There is a voltage reducing adapter included which can reduce the pump down to 7V or 5V from 12V.

Moving on to the 240 mm radiator, it’s slightly thicker than the competition at 30 mm which should give it a slight performance advantage.

Cooler Master have used substantial 10/8mm hosing to connect the block with the radiator.  This size of tubing is readily available online should you want to add other items into the loop.  The hoses are given an extra layer of protection by the black wire coils which surround them.

The pair of included fans are Cooler Master branded and spin at 1600 RPM.  We were a little surprised that Cooler Master didn’t include a second set of screws to attach a second pair of fans to the unit but these can be easily found online.  We admire the inclusion of two rubber fan mounting grommets, though.
