Clutch noise, is it normal?

speedlover

Ive tried doing a search for this, but nothing that came up matched my car symptoms. At any rate, I just noticed my car has a whining/rattle noise. Which goes away when you press on the clutch and returns while in gear or with the clutch depressed in neutral. As you speed up, regardless of gear, the whining gets a bit louder/more noticeable, it becomes more high pitched. Is this normal for Zs? This is first Z i've ever owned, and would like to know if I should take it in to the dealer. My car is a 6 spd mt with sport package.

I don't drive this car often, it's pretty much my weekend fun car. But when I do drive it, the noise is absolutely annoying. Any advice would be greatly appreciated. Thanks!
