The newest Volcano is here and it's a good one. Though I had problems with the variable speed fan, the design still proved itself to be effective and still maintain a stylish look. With more and more people going to a windowed case, good looks is playing a vital role in the sales of heatsinks. It's good to see that you can have a good looking cooler and also receive a respectable amount of actual cooling.
As stated earlier, though, if you have a lot of case cooling, then you might want to consider getting yourself a fan that doesn't change speeds on you. While the concept is very interesting, the high rate of air moving throughout the case won't allow it to heat up enough to activate the fan's higher rates of speed. It will, however, work well in a normally vented case. When I turned off some of the fannage running within my case, I was able to reach the better cooling capabilities of the fan.
Bottom line...If you're building a new system and want a heatsink that looks cool and can also keep your system at an acceptable temperature, then check out the Volcano7 HSF. It is an effective cooler and costs about US$10 less than the Alpha sink that was used as a comparison (and that's an Alpha without a fan).
Very smooth base
Lot of case airflow impedes the variable fan
