When you boot your system up.. does the fan on the card rev up like a [really loud something-or-other] and loud as hell? My systems does this "boost" startup thing.. where it's loud for the initial 5 seconds and then when the Windows splash screen shows up it goes back down to normal levels where it's not noticeable. Is that normal?
