I think that the real question here is this....
each product on the market claims to offer an increase in performance usually 1or2C weather it be fans ,heatsinks ,thermal compound ,case fans or programs that allow your cpu to rest more ...I don't know!
what I do know is this.. there seems to be a lot of companies claiming to give you better performance, when its apparent that they don't... thermaltake case in point they consistently run behind the pack, but when you read there home page it would seem that they are the best thing since sliced bread, there latest greatest hsf has a c/w rating of .64 this fact of course is not made apparent ...to the unsuspecting this won't be realized until its to late after the money is spent and disillusionment sets in...
my advice to all newbies buyer beware wait a little while and look at the reviews ... if you buy on an impulse you might end up with a dead horse
sorry about getting so far off topic just felt the need to *****
