[Vortez] Alpenföhn K2 CPU Cooler Revisited

post #1 of 5

A few months ago, Alpenföhn allowed us to take an exclusive look at their monstrous twin-tower flagship cooler, the K2. In the original review, we concluded that despite the K2’s good performance and superbly sleek finish, it failed to live up to its true potential much to our disappointment. Lagging behind its main rivals; the Noctua NH-D14, Thermalright Silver Arrow, Phanteks PH-TC14PE and even the more compact Thermalright Venomous X, the K2 left itself in a difficult position. So when Alpenföhn contacted me to test a second sample which they promised would give improved performance, I was very sceptical, much of that stemming from the fact that our testing procedures are extensive and there seemed little that could possibly change our results. The reason behind this was the claim that the second sample would be straight out of the production batch rather than a mere pre-production ‘hand-made’ prototype which the previously reviewed cooler was. As such, the cooler we have here today features superior manufacturing and is fully representative of what customers will be able to buy at retail. Perked by my curiosity of potential performance gains, I duly accepted their request so let’s find out if the K2 can live up to its expectations.

It's 8 heatpipes.

I'm not surprised it did not perform as well as some where expecting, at least two of the heatpipes do next to nothing on most CPUs.

Maybe they should have tested it on a G34 processor...

If I'll ever be rich enough to replace my NH-D14 just because of the looks, this will be it.

I don't know why but those fans remind me of those old timer car tires that are partly white.. biggrin.gif

It's surprisingly cheap from what I've seen at CaseKing in Germany and OCUK in England.
