Time to replace my laptop fan?

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?

I'll give it a shot. I've never used compressed air on my laptop and the only time I brought it to a shop for cleaning was when they happen to not have any compressed air (I brought my brother's laptop for cleaning to the same shop beforehand and they just happen to have it back then)! So what do I do with the air? Just blow a bunch of it into my laptop's exhaust? Or do I have to have it dismantled first? I know having it dismantled first would be better but the time I brought it to that shop and they happen not to have compressed air was only a few days ago and I don't really wanna' go all the way back there again just to try this unless I SIMPLY HAVE TO.
 
I usually take my laptop apart as far as I can, but it gets tricky. you can try and locate the inlet areas and blow the air in there, but it will be less efficient. You can take your own compressed air to the shop - that may be the best. Ask for a discount. :) Buy 3 cans - use them in sequence, since the stuff inside freezes when used and it takes a while for it to warm up for max efficiency.
