So my laptop fan is making a rattling noise, very noticeable in idle. Called ASUS customer support and they told me I should get it replace, however my warranty doesn't cover it. Not in a position to spend a lot of money, I also don't want any trouble with continuing using my laptop. Is there any other options I can do to fix my laptop fan? (I should 100% listen to ASUS but really really can't spend money but I really have to fix the fan). If I can't there's nothing I can do, what would happen if I don't fix this issue for the next few weeks?
