One of the two fans in my laptop (Acer 3820TG) has started to make noise at low speeds. It sounds as if it was slightly hitting something light to create a high frequency "clicking" sound (like when you put playing cards on the wheels of your bicycle when you were a kid). This is only during low fan speeds, so could this be that the fan is unbalanced? If so, could it be harmful to the system? (it does seem to blow out the hot air as it should)
Problem is, I can't seem to get the bottom removed. After removing all the screws it is still tight shut... And unfortunately I can't get to the fan without opening the whole thing up!
It does not cause any notable vibrations, so I don't think the wobbling - if present - is very bad. It's just, I REALLY DON'T want to send it back for a 3 week repair now that I finally got a good laptop and SC2...
Gosh I hate to necropost, but you're going to have to open up the whole laptop to the innards.
If you're not savvy enough to tinker around with the components then I think you should just RMA with the manufacturer.
