Fan Noise really loud!

I do not know why this is happening, I have the default fans for everything that came in for the NZXT S340 and the H100I V2.

The AIO fans can be pretty loud, I replaced mine with Cougar Vortex (17 dBA). You could also use Corsair Link to adjust the fan curve on the AIO to be a bit quieter however it won't be as effective for cooling but as long as the CPU stays within safe limits it would work fine.
