Bit-Tech published a review of the OCZ Vendetta 2
A quote from the article:
>> OCZ Vendetta 2 Review
While the OCZ Vendetta 2 isn't silent, or the absolute best thermal performer, it strikes an excellent balance between them considering the £23 price tag. In fact, in some respects we think OCZ might be selling itself short at this price, or we'd happily pay a few quid more for some spare screws and gromits... and a new mounting mechanism. While it might not be up there with the big boys of the Thermalright Ultra Extreme 120 or Noctua NH-U12P in performance, /for the money/ there is very little able to touch the Vendetta 2's performance, both thermally and acoustically.
