Phanteks Enthoo Pro has a weird grinding noise? Also, possible coil whine or something else?

[ProdigyInspired]

I have a Phanteks Enthoo Pro case which seems to have pretty odd behaviour, especially noticeable at night where its quiet.

It's kind of like a grinding noise, something like a metal rattling because of the fan being too strong. The fan is not touching the metal. I've checked all the fans, but I seem to have no clue on what's making the noise. Theres a 200m fan in the front and that probably makes the most noise. I've personally stopped each fan by either just touching it/turning it off, and nothing seems to be making it by itself. The GPU fans aren't running since I set it to be like that on idle.

I can only stop the noise by pressing against the case with my hand or lifting up the case a bit. Still extremely confused on what's making the noise.

I also receive some static from my earphones when I plug it in. My mic is plugged through the back, and I have a G1 GTX 970. Sometimes people can hear the static through my mic. I'm thinking most likely coil whine but I want to make sure.

Sorry for this vague question! If anyone can help that'd be great

What PSU do you have? Also the issue seems to be more of an issue with the angle of the fans considering you can touch the case and it makes it stop or go down. Can you prop a corner up for it to stop?

I have a 850W G2, its fairly new. The 200m is inbuilt and if it's really the angle of the fan then that's a really bad design flaw.

Don't really think its the angles since non of the fans themselves are causing it.

G2 is not the issue. It is one of the best units out there.

I have this case too and sometimes it acts very weird, but basically i think it's the acril window on the side that's vibrating. Notice that there's no amortisation or soft parts between the window and the metal panel. I found that it happens sometimes when there's some temp. changes in the case, but it's enough to lightly knock on the side panel to make it stop. Also try changing the speed of the fans as there's a theory that some fans tend to vibrate at around 900rpm, for example it happens on my corsairs h110i GT fans, but its enough to change set them below 900 or above 950.
