Dell Optiplex AIO 7440 - High noise

Hi guys,

I have a problem with the processor fan on all my computers aio.

The equipment at rest and with work, the fan of the processor blows very high and the noise of the fan is not linear, it is like its rise and fall continuously.

It seems like a rollercoaster in terms of noise. And if it is annoying the noise of a computer, more is accentuated when there are 30 computers in the same room.

Does the same thing happen to you?

Configuration of the bios:

-  Fan Control Override  -  Disable

Performance:

- Multi Core Support - All

- Intel SpeedStep - Enable

- C Status Control - Selected

- Limit CPUID Limit - Disable

- Intel TurboBoost - Enable

- HyperThread control - Enable

Can somebody help me?



Thanks,

Regards,
