Recently I posted that my laptop fan died and I needed to replace. I did. It worked well for a day until it started to do the same things the other one did right before it died . It makes a loud sort of buzzing noise like zzzzzuzzzzzuzzz, it's not steady sort of wavering. Before I supposed the fan had just worn out and was dead. Now I am wondering if I can do anything to stop it from getting worse and dying again. That fan wasn't cheap. Anybody have any suggestions?
