I have a Sony Vaio VGN-CS120J. Basically, the computer fan it sounds like spins more and is louder than what it should be when the cpu is running more programs that take up memory. When i close out of some programs like firefox, itunes, or wmp, it will quiet down as the percentage of memory at use goes down because the program is closed. Why is it so loud?|||The percentage had better carefully go, and not be inordinately overcame on the whole business by the program|||You probably have a lot of dust in the fan.
Basically this is how it works... When you have more programs running, the CPU will get very hot causing the fan to work hard in an attempt to keep the CPU at a temperature that won't cause it to overheat. When you throw dust into the equation it makes it worse.
Dust acts as an insulation, it blocks airflow and keeps the heat inside, which will make the CPU even hotter and the fan will have to work even harder than normal to keep things cool.
Buy something like Endust (aerosol can, not spray) or dust destroyer and clear out the dust. It'll lower the temperature as well as make things easier on your fan.|||it maybe time to change your fan...
accumulation of dust can block the bearings in the fan
hope this helps =)
