Clicking fan

I have a rev A MacBook air, a few days ago it started making a clicking noise from the fan as if a piece of parr was catching, I took the back off and nothing seems to be catching, the sound comes and goes, does anyone have any ideas of the cause, and is it likely to be fatal, and is there any remedy other than booking it in for apple to look at.

Buy another fan. They cost about £2.

Sounds like a bit of crud in the fan. Not an uncommon problem. Have a look at this thread which gives instructions for cleaning and/ or lubricating it.

Ah but you never know. A new fan might have to be some proprietary fan that costs around 70 quid

I forgot what forum it was. It'll probably be a back to base repair job, £70 for parts, £200 labour and £300 for extra special applecare ultra membership cover.

Replacing a fan in my laptops is not a trivial task. It's not something I would undertake lightly.

Find me a laptop that isn't proprietary and bespoke.

Every single one has a different motherboard, internal layout, battery and even power connectors.

Thank you all for the replies, will give the fan a blast of air, and some oil tomorrow and see what happens.

Just a joke. i'd be surprised if the actual fans were propretary

$12.95 actually.
