Seven High-Performance Coolers for AMD and Intel Processors
 

Summarizing the results of this test session I can say that modern midrange coolers are not so far behind the so-called super-coolers even though there is a definite difference between these two categories. However, you can prefer an ordinary cooler like the ones you’ve just seen in this review without fear of a catastrophic performance hit. It’s hard to name an obviously best model among them because there’s a lot of things to see to as you’re choosing your cooler like noise parameters, ease of installation, availability, and price, which may vary a lot in different regions.

Scythe Katana CU truly is quite the performer and the included fan at low speed in my tests measured only 35dBA@50cm distance (inside a case) while performance doesn't suffer much.

for its compact size it offers suprising results.

poor review, has nothing on our master :)

their results are consistent with mine from what I can see
