 Cooler Master Seidon 120M

The Cooler Master Seidon 120M to me looks like a hybrid of designs I have seen in the past. The radiator and tubing are like the CoolIT Systems coolers. The tubing is a stiff corrugated tubing about 12 inches long. I do not care for this type of tubing, due to it stiffness. It just makes life more difficult when installing the unit. The 120mm radiator is 1.1 inches thick and can support up to two 120mm fans for push/pull configuration. The Seidon 120M comes with only on 120mm fan.

The pump/water block housing resembles that of Asetek units; a rounded body, with the 90 degree swivel fittings. What is different is the mounting system and overall outward aesthetic of the housing. Rugged looking, would fit well with Cooler Masters STORM line of cases. The power lead for the housing is XX inches long.

Unlike most sealed loop units I have looked at in the past the Seidon 120M is shipped with no thermal paste pre-applied. Cooler Master does supply a small tube of their thermal paste. This is fine with me, saves on the time to clean off what comes with it so I can use my preferred paste. On the outer diameter of the housing is 4 mounting lugs, these are what the mounting hardware attaches too.

Speaking of mounting hardware the Seidon 120M comes with everything you need to mount the cooler to all modern sockets and enough extra hardware to mount up a second fan.

The mounts fit into small grooves in the side of the housing and attaches to the mounting lugs. The mounting screws are attached to the mounts, when it comes to mounting this will be very handy because you will not have to fight holding the base to the CPU with one hand, while fiddling with loose hardware and a screw driver with the other.
