High pitch case fan niose

[Mr Muggles]

Hi guys

Just put two fans in the roof of my NZXT Hades and when I put the side panel on one of the fans makes this high pitch noise

Any ideas? Don't really want to not have the side panel on if at all possible.

I don't know what "pitch" noise means but I guess it's because of negative air-pressure in ur case? (exhaust fans r pulling more air out of the case than the intake fans pushing in the case ...or the opposite)
just guessing

If it only occurs when the side panel is on, I'd guess either the negative pressure, or that the fans are transferring vibrations to case? If so, do you have any rubber fan mounts to hand?

I thought you used roof fans to push the air out so, maybe I should reverse the one next to fan near the cpu cooler.

Don't have any rubber fan mounts james.

the 2 roof fans (one next to the other) will have opposite directions?

It's an odd one, just have to live with it.

Nice fans!
