Is This Normal?

Well, I'm kind of new to Neoseeker, so if there's a better forum for this question than this one, please redirect me.

I'm wondering if my Wii is normal... Here's a list of some things (mostly sounds) that make me think it may be on the verge of breaking:

• It makes a weird beeping noise when I turn it on and put a disk in it.
• It's usually quiet up until I put a disk in, then it beeps and the fans start.
• It makes a very loud and obnoxious noise that I can't really explain whenever it's loading, and sometimes in-game.
• It gets hot quite quickly.
• It gets dusty rather quickly.

My Wii is the standard white kind, and I have had it for about 2 years. I always have it standing vertically, on the stand.
I know a lot of people say their Wii makes a loud, lawn mower-like sound when they turn it on and it's continuous... mine definitely doesn't do that.
Is there a problem?
Do I need to clean it or change it's position? Is there anything I should buy? Do I need to call Nintendo? If so, where can I get their number?

Thanks.

Well, it's definitely not a high pitched whine. It almost always happens in the following pattern whenever I turn it on or put a disc in:
High pitched beep (not loud or obnoxious, just a small, bleep), low pitched beep, then (when I put a disc in) I hear what I think may be just the disc spinning for a second and then the fans come on.
I saw some videos online where other people's Wiis were doing this...

Okay, thanks.

The beeping noise lets you know when you have put your disk on the Wii.

That's normal. I remember reading somewhere that the Wii was voted the noisiest console of it's time by someone... and it's true. So yeah. Don't worry. As long as it's not doing that lawnmower sound, you're all right. If it starts, trade it in.

I'm sure the disc reading noise is loud, but the Dreamcast's was far louder. As well, I'm sure that the fan on my PS3 (when it kicks in) is a lot louder than anything the Wii can kick up. Just personal experience though.
