What's inside?
Inside you have a huge heatsink with a lot of cooling area. You can also see how three heatpipes per direction lead away from the copper base toward the edges of the cooler, always making contact with the fins. A very nice innovative design.
When the fan is running it will suck air in from the outside and blow it over the fins. Unlike previous coolers from Arctic Cooling hot air will not be exhausted outside the case.
The cooling fan is made by Arctic Cooling and is very quiet as our testing later shows.
