i recently purchased the evga 7600gt co at 580/1500. i really do not think that this fan is noisy. (it does a quick spin on start up and sometimes during games). I was about to buy an extra fan that would replace the one on the 7600gt, but i am glad that i did not as this fan runs at acceptable noise levels. I know that this isn't the bfg which you are looking at, but i beleive they are very simmiliar.
if you are looking bfg looka t this neweg.com one
it is much cheaper and basically the same.
also for cheaper and a better card
really up to you though
