Pros: Works as intended , huge upgrade from stock, matched this with arctic 5 grease and my comp is running 26 degrees idle as compared to 37 stock. I am satisfied.

Cons: It says its max rpm is 2000 not a huge con but maxed out with the fan controller I'm only able to get 1350-1385rpm and thats way more then a +/- 10% difference. Either way not really a con at all because it cools extremely efficiently and is dead quiet in silent mode.

Overall Review: I think I bought the last one in stock =P, first review posted...ever
