Laptop CPU fan buzzing only when flat on a surface

Hi, I hope this is in the right spot. This is my first time posting on the forum.

I recently bought an Asus g752vt laptop, which has two fans. One for the cpu and one for the gpu.
The gpu one works great. However, the cpu fan buzzes faintly, but only when it is on a flat surface.

For example, if I pick it up, the buzzing immediately stops, and, of course, right when I set it back down the buzzing starts up again.

I can even set it on my knee so that the part of the laptop where the cpu fan is located has nothing underneath, and it doesn't buzz at all.

Also, if I just pick up the side where the cpu fan is located just a millimeter, then the buzzing goes away.

So, it looks like the only times it buzzes is when it is set flat on a surface.

I was thinking maybe some sort of vibrations caused by the fan are rattling something, but overall, I was wishing someone here could help!

Oops missed a word there, these fans are blower style cooling devices, when they get worn they easily get out of balance. The blower fins are usually a soft rubberized plastic and when you dirt or wear they get out of balance and cause noise and vibration.

You can disassemble and clean the fins on the blower, but this rarely works, if you're going to all that trouble you might as well have a new one in hand and just change it because that's what it needs.

Sorry, where you saying it is a little loose? And if so, is there anyway to maybe fix it without buying a new fan?
