Arctic Cooling Alpine 11 Pro is focused on silence, not on performance, as written on the box, "Ultra quiet cooling solution for Intel CPUs", and also by its TDP of just 95 W.

However, besides its poor performance compared to most coolers we reviewed recently, it was also not so good on noise level with our CPU under full load. Note, however, that our CPU has a TDP higher than the recommended for this cooler, plus it was overclocked. With low TDP CPUs it will probably keep a lower rotation speed and generate less noise.

But the good point is that it performed a little bit better than Thermaltake ISGC-100, another cooler focused on silence that did not performed well in cooling or in noise level. Besides its better performance, there is a point where Alpine 11 Pro is far better than ISGC-100: price. In this parameter this cooler shows its main advantage, being at least three times cheaper than any cooler we compared it to.

So, it can be an interesting solution to the user that has a low TDP processor and wants to replace the stock cooler without a great impact in its wallet.
