How can I replace the optical drive temperature sensor (922-9214)?
I have a late 2009 21.5" iMac and the fan runs at full speed constantly.
My friend knows a lot more about iMacs than I do and so she tried some resets and has also run some tests on it. She found that the optical drive temperature sensor needs to be replaced.
I have ordered the part (922-9214) and would like a step by step guide on how to put it in the machine.
I have a cousin and a friend who have both pulled apart and put together computers before, so I am planning to ask one of them to put it in for me, but I want to give them a guide to follow.
Any help would be much appreciated. Thanks.
Is this a good question?
