The pictures and article describe this as Freezer i32 product; that product has fluid dynamic bearing. The Freezer i32 CO product has dual ball bearing. Please confirm which fan design is included in this review. It would have been interesting to include a Hyper 212 product in the comparison as Artic has marketed the Freezer i32 as cooler than that product line. Seems unusual to review this product since it has been out for some time and Artic released an updated version compatible with all recent Intel and AMD sockets, the Freezer 33. But, they are so similar in design I'm sure one can infer 33 performance from the i32.
Lastly, what do people think of weight as another factor to consider? There have been several times for me that I see only marginal difference in heatsink performance, but see that one is significantly lighter (say 30%) than another. Wouldn't the lower weight have a positive attribute in that it may reduce stress on your mounting and motherboard and thus result in better reliability?
