Asus Eee PC noisy fan.

Not a lot to this one as I unfortunately didnt take any pictures of the interesting bit.

An Asus Eee PC 1000HD had an intermittently noisy fan. The case came apart fairly easily, starting with keyboard removal, there are sprung loaded tabs along the top row of keys and some tabs that you push on the underside.

You then need to remove all underside screws to release the heatsink plate / top shell.

Here is a pic of it at that stage, you can see the fan on the left, it is between the bottom shell and the mainboard.

Finally remove the screws in the screen hinges / remove all cables to allow the mainboard to be moved clear of the bottom shell, the fan can them be removed.

On the bench the fan was running fine but the fault was intermittent.

Here is a library picture of the fan

The metal plate was removed by taking out the three screws, what was evident was that the fan blades had been rubbing on the metal plate and scored a groove in it, its possible this was creating the noise.

The blades lift off , the shaft is located in a brass bushing, wear of this part may have caused the rubbing. The bushing was lubricated and the plate re fitted with washers spacing it slightly away from the blades to prevent rubbing.

We will see if this gives it a new lease of life, I will report back how it runs in the long term. A new fan is not so much £10, if I had known before I was asked to look I think I would have just told them to get one to replace.
