Alpenfohn K2 Review

Introduction and Technical specification

 Alpenfohn K2   

 

Introduction and Technical Specification

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 enough

Standing 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.

Twin tower with 8*6mm Heatpipes

  • The new Twin Tower Design can reach best results in noise and performance by using a combination of 2 fans.
  • The trapezoid finshape ensures better compatibility with VGA coolers by keeping the distance to the PCI-X Slot
  • All contact surfaces between Fins, Heatpipes and the baseplate are soldered.

 

Heatpipe/Baseplate

  • The U-Shape Heatpipes offer a large connection area to the baseplate for a better heat absorption
  • By CNC machining the surface of the baseplate is perfectly even and the thermal transfer is optimized.

 

Fins

  • K2 is the first cooler to feature the brand new Minimized noise Transfer at low Airflow-Technology. The advanced finstructure influences the airflow through the heatsink to increase the heat transfer to the air.

 

Wing Boost 120/140mm Dual-Combination

  • Equipped with integrated decoupling elements, WB technology and HD bearing K2 comes with each one 120mm and 140mm Wing Boost fans.

Top of the range dual tower heatsink from German manufacturers Alpenfohn but will K2 be a mountain or a molehill?

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.

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!

dude, it was just a friendly suggestion, no need to delete my posts, because you ran out of arguments.
