The fans make extremely annoying sound that I cannot stand. They can range from quiet annoying and most of the time, loud planes. It seems that when I lightly push down the sticker area of the fan (in the middle) the sound goes away. And yes, it is mounted correctly. Does anyone have an idea as to why they sound like this? Please help, this is getting ridiculous.

I uploaded a video demonstrating the noise coming from the fans:

Here's how it regularly sounds: https://www.youtube.com/watch?v=xnf3V_W0me8&feature=youtu.be
Case: Nzxt H440

And also another thing: The fans begin to sound like drilling noise in even intervals

Here's a lad with the SAME fans as me, doing the same sound as my fans:

My GFX card fans did that too and the support team told me it was the bearings. Getting a replacement, but I think it was the fan's blades being off, causing it to rattle regardless of if it was mounted correctly.

It's maybe that, I'm going to test it because the sound is unbearable. (pun intended)

Wait man before you jump to conclusions and junk them, turn them on and look really closely at the edge of the propellers spinning. If they're tilting, that's the cause. It's pretty common with larger fans. If you've ever bought a ceiling fan and got those little weights for adjusting the blades, that's what they're for. I'm just presuming that because it's not a constant sound, it's in intervals (like my ceiling fans do when they're tilted).

P.s. Nice case

Yes, they ARE tilting. I even let loose a screw each fan and lifted them and the sound was gone. I tried this a few days ago. The question is however, how can I fix it w/ proper mounting?

And thanks.

I bought one, had it for 3 days. threw it away. Out of the box it sounded like the first video you linked. I had mine mounted on a side panel.

After buying a bunch of real cheap Cooler Master fans, I'll probably never touch another as long as I live. Except for the Jetflos, but in that price range there are better options. lol.

You know what guys? I disconnected the fans and Everything is so quiet now. I think I'm going to remove the blades and keep the Red LEDs on and that way I can enjoy the show without disturbing sound. What a sad way to spend 30 bucks on. Oh well.

Any fans you can recommend? (That don't sound crappy like mine)

I don't really care about noise but when I do, it's when the fans start to rattle loud like the current ones I have it and I can hear it through my headphones when listening to Music.

When I disconnected the fans it sounded like heaven compared to before. No rattle, no bs.
