CoolerMaster MasterLiquid Pro 280 Review

 Up close:  Rad and Pump.

The Pro 280 is very similar to the 240 in all respects, but as the name suggested it's designed to work with a pair of 140mm fans as opposed to 140mm units.  The system uses what CoolerMaster refer to as FlowOp technology, which in essence is a series of measures made to Optimise the Flow of fluid away from the hot CPU and contact plate, while preserving the lifespan of the components.  The Pro 280 has a fin density of 21 fins/Inch, and has 19 visible water channels, making it quite dense.

The Pro 280 uses a design that a boring conformist from Helsinki might associate with.  These fins are designed to optimise airflow while maximising surface area.  We're not convinced ourselves, and as the fins on the radiator look nowhere near as "square" as the ones shown on the website graphics, we're not entirely sure that this person prom Helsinki is as un-hip as CoolerMaster would have us believe.  As you can see, the Pro 280 is also designed to work with 142mm fans as well as the 140mm fans its name would suggest, which might improve compatibility with cases only designed to take a 240mm unit.  Obviously you're going to loose a little oomph from the fans though.

CoolerMaster utilise a dual chamber pump, which is designed to keep the warm coolant in the lower chamber while the vital components reeside in the upper chamber.  This approach they claim will increase the lfe expectancy of the pump housing by a factor of 2.5.  Giving it a logevity of 127,000 hours, which in rough terms is just a smidge under 20 years, all of which is very impressive, but we're not sure it has real world advantages. 

The other thing worth mentioning with regards to the pump is that the tubing is attached to opposite sides of the housing.  Here at OC3D we've got mixed feelings, with some preferring the aesthetic, and others being a bit bothered by the way it can make the tubes sit when it's attached to the CPU.

The copper contact plate on the Pro 280 is a thing of beauty, with Coolermaster claiming it to have an internal structure with 657% more surface area.  More surface area than what, they don't say, so we can only assume they mean a flat sheet of Copper.

The Cooler comes with a pair of 140mm fans which are very far from being mere stock fans.  As you can see not only do they look sexy, but they also comes with rubber isolation dampeners on all contact surfaces.

Fitting the Pro 280 is a piece of cake, thanks to the intuitive design and well thought out instructions.
