Help with vibration problem Predator G3-571

Qua

I'm newer to the laptop/computer business, so I don't know many bits and pieces. I don't know many of the part names... so excuse my ignorance, please.

Here are the details:
Laptop (Predator G3-571) is vibrating constantly, and very audible. 
It is not the fans, the bearings are fine and the fans themselves do not vibrate and do not increase vibration... from what I can tell. (and I did clean them and re-screw.
I did add a SSD to the additional slot, which works.

When fans are low/auto:
Vibration is felt on top of extra SSD (keyboard side) but when I check it from underneath, it's not that bad. However, the vibration *is* mainly on the right side.

When fans are turned on max:
Vibrations are not near the SSD, more towards the power/usb area...?

The vibrations begin as soon as I turn on the laptop. They seem to fade away at random points, sometimes gone completely, then they rev up again to the point where I can't hear the audio over the vibration. It sounds like... buzzing. 

I will try to answer as many questions as possible ;=;
