Alpenfohn K2 Review

Up Close: The Cooler

Alpenfohn K2


Up Close:  The Cooler

The K2 is of the twin tower type, with 49 Aluminium fins in each stack.  Each stack is 50mm deep by 140mm wide at their widest point.  The 8x6mm heat pipes are distributed evenly in a linear pattern along the length of each stack.

The leading and trailing edges of the fins are left open for air to pass though, but as is becoming quite a common feature these days, the sides of the fin stacks are closed off giving a smooth edge to each of the outer edges of each tower.  The  inner facing surfaces of the stacks have a saw tooth effect, whereas both of the outwards facing surfaces have a large trapezoid finish to them, presumably to aid airflow over the fins.

With the fans attached we get a better idea of the size of the K2.  The fans can be mounted on either surface and in either direction, however it is intended that the 140mm fan sits in between the towers whist the 120mm fan sits on an outer surface.  In mounting the fans it is of course necessary to pay attention to their orientations.  If they're blowing towards each other they're not going to be doing a lot of good are they?

The fans themselves are quite nice little units.  The 120mm is of the traditional square open corner construction whereas the 140 has a more circular outer cowling.  both fans have mounting holes spaced for 120mm mounts and attach to the body by means of wire spring clips.  The inner cowling of each fan is made of a White hard plastic and appears to be removable as with the BitFenix fans I reviewed a little while back.  The black portion of each fan is finished in that rather sexy to the touch soft touch plastic rubber.  Mmmmm Niiiice.

thank you GW. yeah, it looked like a contender for the title, too bad the 4.4 test bloodied
the fight, but the nominal usage looks good. the fans are quite different with the 2-tone
feature. thanks again

Benchmark tests were done during case changes and were always within tollerances of each other.

ie: the cases used made no difference from one to another how the heatsink performed.Quote

This was the test i've been looking for!

I'm kind of surprised to see that the K2 falls behind the "big boys" significantly, while other reviews place it straight above the NH-D14!Quote
