German manufacturer Alpenfohn specialise in cooling solutions.  Whether it be VGA, netbook or just old plain and simple fans.  The K2 comes from their mountain range (Sorry couldn't resist) of CPU coolers and is currently the biggest cooler Alpenfohn produce.  I do get the feeling that by naming it after the second highest peak in the world Alpenfohn have left themselves a bit of room for an even larger cooler should they decide that the K2 simply isn't big enoughStanding 160mm tall, with twin towers and no less than 8x6mm heat pipes the K2 falls into the category of super tower, directly challenging the likes of the D14 and the Silver arrow.
