Weird Harddisc(?) Noise coming from my iMac 21.5", please advise...

I bought my 21.5" iMac back in August when the new batch launched.
It has been working fine until a few days ago..
I noticed a weird sound after I switched it on...
I tried to restart it but the noise is still here..
It goes away after.. around 20 - 30 minutes of usage..
But I am still very paranoid as to what has caused the sound!

Attached is a video where I managed to capture this weird noise...
p.s there are construction noises in between but the HD noise is still very evident.

What should I do???

Defiantly the fan. You're machine is under warranty, bring it to apple and they will replace the fan.

thanks a lot for your help.
It doesn't bother me that much as the sound goes away after 15 or so minutes
but I am just scared that it might cause damage to my machine or sth
is it a problem?
of course, i don't mind bringing it back to apple to fix it, but only if its necessary. this thing is heavy man...
 
it seems to bother you , so why the hesitation to go to apple and get it fixed as you got apple care and exact thats the reason someone gets apple care , just for the case if something doesn't work like it should ,ok if you can live with it , but if a fan starts making noises it wont be too long before it fails and that could cause trouble , especially when it happens after your apple care ends in two years and you have to pay for the fix ;)

so dont wait until its to late , if you would hear a sound that unusual and wasn't there before coming from your car , you would not wait until the car breaks down would you?
