Hi
At the risk of sounding facetious, what sort of noises?
The only moving part is a fan, and if that is noisy it may be about to fail. If it does the switch may overheat and fail totally, so a hardware fix is required for the fan.
The only other things that make a noise are the power supply, which may again be about to fail so needing a hardware fix, or possibly 'crackles' from a poor contact on the mains lead/receptacle as AC enters the switch. Reseat/clean this to fix.
