and my main switch a Cisco 3750G.
I thought its the Cisco one so i looked at logs and such all seemed normal * even at env temp shown at 50-51 degrees Fan reports OK and Temp OK *not even yellow alert*
when it did noise the next evening i checked inmediatelly but I saw all is still ok temp is the same 51 degrees celsius.
I turned it off... And guess what the noise did not stop even tough I could have sweared it was coming from there
