So I have a 3- to 4-year old laptop and the fan has recently been acting very erratically. Sometimes, it works just fine; other times, it makes a significant amount of noise and DOESN'T blow any air out of the laptop. It's split at about 50-50 at all times, changing from functioning fine to not functioning fine every few minutes. And restarting it is just like flipping a coin too; heads means it'll work fine and tails means it won't. I sent it to a repair shop and they said all the connections are fine. What they did was disable the automatic fan speed control; now, they said, the fan would constantly blow at maximum rpm. Needless to say, I wouldn't be posting this if that had worked; it's still going on exactly the way I described. I brought it back to them and they offered to have a new fan shipped here for me from Hong Kong (I live in the Philippines, and passing through customs in the Philippines takes FOREVER!). So do you guys think I should get a new fan and that that is indeed the problem: an old, dying fan? Or do you guys think it's some sort of other problem with my laptop?
