Is this a normal sound

280z/300zx

I was just curious if this was normal for the VQ engine. Since owning my 370z for the last 2mo (650miles) it's had this chirping noise coming from the engine while running. It's constant and seems to speed up as the engine speeds up. You can only hear it if you are standing outside the car while it's running. It's not very loud but enough to hear it if standing with in 5ft from the front of the car. Just not sure if this is a normal VQ sound just like the ticking you can hear at the top of the intake manifold. I'm probably going to go by Nissan tomarrow and listen to one of the Z's on the lot to compare. I just hate the thought of possibly having to take my car in for service and letting someone else drive it. Hoping it's nothing to worry about or possibly something I can take car of myself. thanks in advance.
