Agreed with tigerbay. BACKUP FIRST!!!
Most likely a noise will be dust in the fan(s).
0. Do a backup.
1. Figure out where the fan or blower is. Just wet your finger and feel around any grilles. Many Dells have their fan on the underside.
2. Get a compressed air can blow into the fan grille. This should dislodge any dust.
3. If that doesn't work, check warranty fixes.
- Repeat cleaning regularly. Better to prevent than to cure.
- Eventually, the fan will get really fouled. I would personally open up the machine and clean it properly then, but it's not for the novice. And it will void the warranty if you still have it.
