Re: gtx 480 users, what speed (% wise) do you have your fans at?
Stock (44%) ranges around 44-46C and full load 86C (65%). With a custom fanprofile that raises the speed in a more linear way I have obviously the same idle speed/temp but under full load its 75C at 75%.
I only have a single 480 and two slot space between the card and the X-Fi.
