Please refer to the X440 datasheet: Fan Speed and Acoustic Noise: http://learn.extremenetworks.com/rs/extreme/images/Summit-X440x-DS.pdf
Has the noise increased over time?
If it is excessively loud, I would suggest opening a case with GTAC to troubleshoot the fan issues.
It is optional to do a dB(A) test to verify the noise level.

the general answer is to decrease the temperature. there are different fan speed levels based on temperature.

what temperature is recommended for all these switch mentioned above

as per the following article - below 30 (sensor temp) the fan will run on half speed and >30 on full speed

you mean to say that if it is (low temp below 30) switches run normally no noisy sound or if it is (high temp) switches make noisy sound.?

<30 = half fan speed
>30 = full fan speed
So the fan will allways run no matter what the temperature is.
But if the temperatur is greater 30 the fan will run with full speed = max noise.

Offtopic - is there any loud specification about Extreme EPS-500?

I turn it off when I need to be in server room... 🙂
