This is a preliminary review of the Coolermaster Seidon 240M self contained liquid cooling system. The Seidon 240M is a large all-in-one liquid cooling solution built around a 240mm aluminum heat exchanger equipped with twin 120mm fans. The large heat exchanger is intended for top-mounting in full sized gaming cases. Small diameter FEP tubing connects the integrated pump/waterblock to the radiator and the waterblock incorporates micro skived copper base plate. Coolermaster's Seidon 240M installs onto Intel socket LGA775/115x/1366/2011 and AMD socket AM2/AM3/FM1/FM2 processors. Retail price is about $85 USD / CDN. Please see coolermaster.com for the full spec sheet.

NOTE: In an effort to keep up with the increasing pace of heatsink releases and provide a timely reference to our readers, Frostytech has decided to release its heatsink test results in a preliminary review format as soon as the data is compiled. Contained within this preliminary article are the complete set of test results charts for Frostytech's 125Watt AMD, 150W & 85W Intel LGA115x/775 and 200W Intel LGA2011 synthetic thermal test platforms, acoustic measurements and a 360° pictorial overview of the thermal solution. This preliminary look at the Coolermaster Seidon 240M will be updated to the complete review at a later date.

Mounting Hardware

The Coolermaster Seidon 240M is compatible with Intel socket LGA2011/1366/115x/775 and AMD socket FM2/FM1/AM2/AM3 processors. The cooler ships with a universal motherboard bracket and a pair of metal mounting brackets that attach to the pump head to facilitate each particular socket. A rubber gasket is included which sandwiches between the fans and heat exchanger, cutting down on errant noise and creating a bit of a plenum behind the fans.

This heatsink will be tested on FrostyTech's Intel and AMD version of the Mk.II synthetic thermal temperature test platform, and compared against hundreds of reference Intel and AMD heatsinks. The whole test methodology is outlined in detail here if you'd like to know what equipment is used, and the parameters under which the tests are conducted.
