    This might already be posted here, but I've never seen it anywhere.

    My ACER laptop fell off a chair. Started it up, and the CPU heatsink fan started making a noise like it is rubbing something. But I noticed it would quit when the laptop was tipped on it's side, or upside down.

    Took the back off, and could not see anything that looked like it was crooked, or bent. Removed the fan housing, and noticed that the fan blade was loose, and wobbly. I have a couple of heatsink fans from other laptops laying around, and checked them. Nice and tight. No way to modify one of those to work, and did not see the correct fan for sale online.

    So, I decided to see if I could pry the fan off, and then replace it with one of the good ones. When I lightly pried one side of the fan down, and then pried the other side....it popped into place. No wobble, nice and tight! So I looked at the other two fans. All of them have what appears to be a fiber washer between the fan and housing, but do not rest against it. There is like a mm space.

    So.....check that before you order a replacement fan if yours suddenly starts making noise after a bump.
