you could undervolt it to reduce noise. The link to a guide is shown bellow, but I preffer centrino hardware control over rmclock.
Wow, is it just my imagination or is my laptop's fan getting noiser and noiser each week? Is it a sign of wear and tear as well?
Is there a way to replace the fan and have a much quieter one? It's gotten to a point where I need to turn off the laptop, so I can get some sleep!
