After working on two computers with this guide may I add a few things:
- remove the old adhesive on both sides (screen and casing) just after opening. You can already put the new strips on the casing but keep the adhesive covers on the other side
- I would always remove the logic board instead of working with screwdrivers behind. The risk of damaging something would be too high for me and it doesn’t take ages and isn’t too hard
- if you have no magnetic screwdriver and a hard time getting the screws for the air duct in, use a tad of hand cream or similar on the screwdriver. That should make the screw stick if you have slow movements
- always try the computer before you glue the screen back on after finishing! The first time I did glue everything together just to learn that the RAM was faulty. And it is much harder to re-open new adhesive strips.
All in all a superb guide, making a complicated repair quite simple.
I did change my fan according to this solution as it became louder every day.
Getting the fan was a bit of a search - I finally found and ordered it directly from an online shop in China.
When changing the fan the rubbers holding it are quite something to handle - you need a lot of tamper to make that happen.
Being very careful regarding the connector and it’s socket at least to me there was no difference to other connectors compared to eg. a 2013 iMac where I just changed the HDD and the RAM.
So if you are careful and don’t use at lot of force the connector shouldn’t be a problem.
I didn’t have to use a heat gun, the heat the old hard drive of my TC (which I also changed) was quite enough to peel the bottom layer of.
Thanks for this guide!
