The Accelero X2

The fan and top of the cooler are painted black with a large Artic Cooling sticker across it. The AC logo is very prominent, along with the name of the product (Shown with a large X2 on the right hand side).

The underside has a copper core that is covered in Artic Cooling's own brand of heatpaste. The heatpaste is designed to be the perfect size to fill all the mircoscopic gullies in the base of the heatsink. Using AS5 anyway can sometimes yield temperature improvements, but usually in this kind of situation it is best to stick with what you're given; though it can't hurt to experiment.

The copper core is surrounded by a large surface area aluminium heatsink with a large set of aluminium fins:

Running through these fins are three copper heatpiptes. Heatpipes are hollowed pipes (Usually copper) that are either filled with a liquid with a high heat conductivity or a fine powder (Again, usually copper). Both these methods are far more effective than using solid copper or aluminium to transfer the heat therefore they are used to provide a pathway for the heat to travel from the core to the large surface area of the heatsink fins.

The fan supplied with the Accelero X2 is quite small compared to some of the larger coolers out there, but hopefully this will not hinder the performance of the cooler. One nice point to mention here is that the fan is backed and mounted on a small piece of rubber which helps reduce vibrations and hence reduces noise.
