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.

i have to open the whole laptop so to look at it.

Hello atSizzlers;

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

The sound puts me in mind of a fan blade rubbing up against a foreign item (a piece of cardboard or other debris?). Or maybe something internal in the laptop near the path of the spinning fan blade - a wire drifting over near the fan?

A bright light and a visual inspect of the exhaust port before diving into the internals?

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.

I'd get to studying up on how to get at the fan if I were you.
In the long term, I'd worry if it's some internal wire rubbing on the fan.

 

[atSizzlers]

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

 

[WR2]

Any rubbing on a wire is not a good thing.
'hardly hear it' isn't the same thing as 'not rubbing'.

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

 

[WR2]

Still under warranty?

 

[atSizzlers]

Yes it is.

 

[WR2]

I'd give Acer a chance to help you out. Nudge them a bit.
See if you can get the service manual or fan access instructions from them.

 

[atSizzlers]

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

No problem. Most tech's who work on laptops on a regular basis can handle that type of job.
