Alienware 15 - Chassis Vibrations

Hey everyone!

I recently purchased an Alienware 15. Everything works great, but I have one concern ...

Whenever the GPU fan starts (I think), the chassis starts vibrating. The vibration is very minimal and cannot be seen or heard. However, if you place your hand over the chassis (e.g. to the left and right of the trackpad), you can feel the vibration slightly. It's like a buzzing feeling.

Although the issue seems small, it does get kind of annoying when I'm using the keyboard (my wrists rest on the chassis). The keyboard also (to a lesser extent) has that buzzing feeling, but you have to concentrate to notice it. 

I'm wondering if this is a common issue to the new Alienware 15 (or Alienware 13/17 for that matter)...

Does anyone else have this problem? Or is it just designed this way?

Thanks!
