The title tells it all. I am asking as I replaced the original fan on my current Sonnet 1.2GHz card and I am now going to upgrade to a Sonnet 2x1.6GHz card. I don't think that Sonnet has replaced the fan to a less loud one on that card? I have seen pictures of the Sonnet 2x1.6GHz with both 1 and 2 fans. So I am a bit confused now.
