The V8 outperformed all the coolers in the comparison, although not by much in a couple of cases. Frankly, I expected a bit better performance out of a cooler of this immense size, particularly at full fan speed. But, there's no question that this is a very good cooling solution.

Nice cooler, I have one in my rig

That is one monster cooler and its good to see CM can play with the top dogs when it comes to CPU coolers.
