Strange laptop sound

Hey guys wanted to give me quick opinion of my laptop sound is this normal http://www.youtube.com/watch?v=M8U [...] AAAAAAAAAA

Iv been long time pc user but switch to laptop and not very into this thing yet so to ask ya.Some say its perfectly normal,but i dnt recall hearing this when bougth the laptop week ago.Its acer aspire 5750g i3 2.10ghz 4gb ram 500HDD

Sounds like your fan. May be its not set right or is loose or bearings are shot. Try and take a look at your fan, it should be accessible, see if you can see anything not right. If not, go back to Acer and see if they can help.

Hello atSizzlers;

It's certainly seems to be coming from that upper left quadrant where the cooling fan is probably located.

Strangly i hit it a lill bit on the fan and noise aint so constant as it used.I suppose somethink is inside rubbing on the fan.So im gonna open it and check it

hahah now sound is less noticable when not playing game or watching video.Lol myself was afraid to open the laptop since its all electronics in there.So i blow up nicee air on it and seems it is part gone.

Yea but if it was a wire wouldnt be non stop rubbing atm i hardly hear it.Btw i would study but older acers got it easier while on mine i must remove the whole back to check the fan

I cant find anywhere on how to disamble 5750 series mate,not videos anywhere

Yes it is.

Nah im not americano mate so this acer is far from me,the company i bougth from ima go tommorow and ask em to open it for me and check it.Stil thx for replying
