How can I decided which model fan to buy for my Air?
I'm a bit of newb when it comes to Macs and I'm very protective of my Air.
Recently the fan has started to become really noisy. Luckily it still works and is quiet when get on a level surface.
I now want to replace the fan myself using the fantastic guide on this site, but I am really unsure about which fan I should be buying.
How do I find out which model fan I need?
I have an A1237 Air.
