Cooler Master Seidon 240M All-in-one Liquid Cooler Review - Final Thoughts

What impresses me the most about the Seidon 240M is not necessarily just its cooling performance, but how quiet it was while we were cranking 4GHz+ overclocks.  Once we got into the 4.2 GHz range the fan started to ramp up where the noise levels became more noticeable outside of the case.  At full speed, we were able to maintain low-50 degree Celsius temperatures with a 4 GHz overclock fully loaded for over an hour, and again the noise levels were something I could live with as my everyday computer.  We'll be testing this further with a push/pull configuration once our pair of matching fans arrives, and we expect this to allow some serious overclocking potential over the great performance we see out-of-the-box for those who are wanting to begin dabbling in watercooling or even seasoned overclockers.


Aside from its great performance, the Cooler Master-designed and manufactured Seidon 240M comes with a slim pump housing and industrial aesthetics that are simple without being boring either.  While some may prefer a simpler design on the pump housing, I doubt anyone will fret at the slim profile of the base itself, and lends itself nicely to keeping the processor socket looking clean and organized.  The blue LED, nicely diffused behind the smoke-grey housing, gives an aura of flowing water and is a subtle sign that work is being done under the plastic cover.


The bane of traditional watercooling setups, and many aftermarket CPU coolers for that matter, is the installation process.  The Seidon 240M has a pretty straight forward and easy-to-manage installation process that I showed can easily be done with only one pair of hands.  Cooler Master, for their last handful of cooler designs, does a great job of breaking up their mounting designs so that they can be done in bits-and-pieces as opposed to a single tricky operation requiring abundant patience and dexterity.  This also enables Cooler Master to easily design universal mounts for their coolers, so anyone packing Intel or AMD can get in on the fun.


At an MSRP of $99.99, Cooler Master also comes in $10-20 cheaper than the Corsair H100 series.  Cooler Master probably is afforded a bit more pricing flexibility since they manufacture the coolers and don't re-brand them from Asetek or CoolIT like most of the other all-in-one water cooling systems on the market.  For great acoustic and thermal performance, simple setup, and a competitive price, the Seidon 240M looks to be a winner for beginners to liquid cooling and enthusiasts alike.
