My laptop makes a loud intermittent whirring noise, when opened up the noise seems to originate from the ssd area (bottom right of the key board). The fan noise is also extremely loud - there are currently no BIOS updates available, 'fan always on' has been disabled and the power save battery option has been selected with no effect on overall noise. There is also no dust within or around the fan. Any advice on how I can quieten my laptop? My sister has the same laptop and that is silent.
