Constant humming that stops only when tipped at an angle

My brand new laptop, Lenovo Y700 has this constant low humming. It starts the moment you turn the laptop on, before even Windows loads. The fan also turns on when the laptop is turned on, but only when Windows loads, and runs constantly, even though the laptop is brand new, no programs are running and there's nothing installed except what came with it.

As I type this, I have nothing else open but one window on Google Chrome. Yet along with the humming, the fan is running loudly and it speeds up and slows down a lot. The low humming is more annoying than the fan though, but I don't see why the fan should be running so loud either.

The humming stops when you pick up the laptop and turn it in the air so it's not horizontal, but maybe at about a 45 degree angle. Doesn't matter if you tip the front, back or one of the sides, tipping it diagonally makes the humming go away.

I also know it's not something that is just normal with this model, since I already had a laptop of the same model that had other issues and I exchanged it for a new one within days of getting it. This is the one I got in place of it. The first one didn't have this humming problem and it didn't have the fan running constantly, it only ran loud when the pc got hot.

This laptop had another issue with freezing when i first got it, so I sent it in and they fixed that by changing the SSD and I've just gotten it back, but the humming problem still exists, wasn't fixed, and the fan thing too.

What could the humming be and why is the fan running so much?

(NT) Better return it if they can't fix it.

And if the next one does it, give the Asus ROG 17 inch model a look.
