My fan is always loud and running...

Specs: Windows 7
My fan is always on and running and it's driving me crazy! Even when it finally decides to quiet down, I still hear this whistling noise coming from the fan; I can always hear it no matter what! It's not very old (8 months) and is always used on a table, so I can't imagine it's very dusty. Can anyone tell me what it might be?

Are you sure it's the fan you're hearing?

If you have disk in your DVD drive, Windows will spin it at seemingly random times, even when you're not accessing it yourself, and it's activity led doesn't necessarily come on when it does that - optical drives can be quite noisy.

Get a can of compressed air & shoot a good blast into the cooling vents.

Yeah, I'm positive it's the fan haha. I know what the disc drive sounds like, but it's on the other side of the laptop. Do you think the can is worth it? Or should I get it checked out?

I just started researching this today and it has just been about an hour long where I think I might have solved my racecar sounding fan. I took off side cover and found loads of dust everywhere and on/around the 3 fan areas I have inside my HP; I put computer in "sleep" mode and made sure I didn't touch any electrical/hot areas and used a shop vac to clean it out. Could I have been this lucky??? On someone's post I saw this advice and didn't necessarily think it would work. Maybe when the fans have to push through smaller holes the friction turns to loud sound.

You were definitely lucky. Using a vacuum on a computer is asking for trouble. Jam's suggestion to use a can of compressed air is the proper way.

dust and dirt may always be the source of this...
but the fun may really be failing...

"Using a vacuum on a computer is asking for trouble."

They produce a tremendous amount of static electricity while running, unless they're specially designed to be used on computers, and can discharge that to anything on the computer from anything connected to the vacuum, including from the person who's using the vacuum.

Thank you guys!
I'm taking it in for professional cleaning because my warranty isn't up for almost another 2 years and I don't want to do anything bad with that can of air.. haha.
