Why is my computer so noisy?

Sometimes my computer sounds like it is taking off or like a vacuum cleaner sound. Is this normal or could it be there is something wrong with the fan?

This does not happen every single time I work on it, but it is kind of annoying.

I have a Dell Optiplex GX280.

Thanks for your help.

Take a cover off & clean out the dust, put an external fan on & see if it behaves with the extra cooling. Make sure all the fans ( including the power supply ) are spinning fast.

Try taking the CD(s) out of the CD drive(s) when you aren't using them.
Some CD drives are noisy because they vibrate, especially when they are spinning faster speeds, and if it has a CD in it Windows will spin the drive while you boot, and, this some people are not aware of - will spin occasionally while you are using your computer, even when you are not actively accessing the CD drive, and often without lighting up the activity led on the drive.
Also check for loose screws where drives are mounted - if some are loose a CD drive that vibrates will make more noise.

See response No.1 The cooling fins in front of your fans may be full of dust. How old is the unit? Your fan/s may be working overtime becaus the cooling fins are clogged. We dismantled a Toshiba recently and the dirt that came out looked like knitted felt.

Once I thought I was wrong, now I'm not so sure!

Thanks guys for your help. I am going to follow your advice and clean the system. We have had this system for about 2 years now and it is very likely it is all dusty inside.

I do not think this has to do anything with the CD drive, since the noise seems to come from the CPU.
