We have seen a flood of new all-in-one liquid cooling solutions from many companies since CES ended this past January. Xtreme CPU has reviewed Swiftech’s H220 and the Corsair H110 is coming soon. Today, we mount Cooler Master’s Seidon 240M in our testing rig and see how it performs compared to the rest.

A refreshing bit of info on the Seidon 240M is that Cooler Master claims it is not a carbon copy from CoolIT or Asetek, but one of their own designs. Briefly scouring the OEM pages, we see no mention of Cooler Master as a partner. That is a good thing.

Our first introduction to the Seidon line of liquid coolers from Cooler Master came from the suite tour we had at CES. After seeing the unit there, we were very interested in testing it out, especially after seeing what other manufacturers had to offer. If you can remember back to 2004, you will recall that Cooler Master introduced the first AIO liquid coolers, the Aquagate series. A bit ahead of their time, no doubt. Adaption of liquid cooling was not as popular as it is today.

Simplifying water cooling has made these units easy to maintain, install and replace. What is of interest to us is performance, installation and maintenance. We will take a look at what makes the Seidon 240M different from the other products we have, test it and see where it stands.
