Closer Look


Front view

From the front we can see a deceivingly dense fin array that looks more open than it truely is. This is caused by the tapered trapezoid fin shapes and allows for better air penetration. From the copper base we can see the 6x 6mm U-shaped heatpipes pierce up through the sides of the fins up to the top plate.


Matterhorn Pure Base

The 6 heatpipes are sandwiched between a copper baseplate and a profiled lump of aluminium. Through the top of the base plate there are some thick fins and at the centre is a thick cut channel to house the retention plate. The heatpipes are slightly staggered in a left to right fashion which helps distribute heat amongst the fins more efficiently.


The baseplate is lapped to a reflective shine

The argument still rages as to whether a direct touch or flat baseplate to distribute heat is better, though I for one prefer a flat mirror like surface and the Pure doesn't disappoint. The baseplate measures 39mm x 50mm and easily covers a Sandy Bridge-E CPU.


Razor test

The baseplate is perfectly flat in all directions and passes the razor test with flying colours.


The 120mm WingBoost fan

Designed by Alpenföhn themselves, this PWM fan moves between 500-1500RPM moving up to 108m³h (that's about 63CFM) and has the duty to remove the heat from the tower. An interesting feature here is the 'Plus-function' which is an integrated splitter that allows you to 'piggy back' another 4 pin PWM fan via the same motherboard header to allow for a controlled push-pull setup. The only downside to this is that only 2 fan mounting clips are included so to use the Matterhorn Pure in push-pull you will need to source another 2 fan mounting clips.


Underside of the fan

On the rear of the fan we can see 4x anti-vibration mounts which can stop any potential noise or rattle while the fan is in operation.
