Introduzione
Replacing a defective fan will keep your laptop running cool.
-
With the case closed, place the Unibody top-side down on a flat surface.
-
Depress the grooved side of the access door release latch enough to grab the free end. Lift the release latch until it is vertical.
-
The access door should now be raised enough to lift it up and out of the Unibody.
-
Grab the white plastic tab and pull the battery up and out of the Unibody.
-
Remove the following eight screws securing the lower case to the chassis:
-
One 3 mm Phillips screw.
-
Three 13.5 mm Phillips screws.
-
Four 3.5 mm Phillips screws.
-
Make sure you have a good quality Phillips screwdriver. Mine had removable tips and had a small play at the connection. As a result I didn't have a good feel and damaged my screws (those securing the fan and the top left in step 23). Game over for me installing new thermal paste...
Be very carefull with your screws! Especially those on the inside.
-
Using both hands, lift and remove the lower case off the upper case.
-
Use a spudger to pry the fan connector straight up off the logic board.
Is there anyway to solder the fan socket back on to the mother board? It broke off :(
Solder back to the mother board!
Me too!!! WHAT NOW?
solder back to the mother board
It helped me a lot to look at the closeup pictures of the fan connector socket on the motherboard and the fan connector itself. Then I could figure out where to apply the axial rotating pressure with the plastic "spudger" (a trimmed old credit card). Needed more force to remove the 7-year old connection than I felt comfortable with. The pic's helped with the leverage point to use - just past and under the fan wires BUT not on the board itself.
Excellent guide! Moved fan from MB to MBP and installed new fan in old MB.
-
Remove the following three screws securing the fan to the upper case:
-
Two 5 mm Phillips screws.
-
One 7 mm Phillips screw.
-
Screws were locktited and I have stripped head of right one while trying to remove it…
-
Lift the fan out of the upper case.
One of the screw was messed up. How can I remove it ?
Two of my screws did not want to come out when I used Philips #00 and it damaged the screw so now I don't know if I will manage to get it out. What can I do?
Don't know about ruined screw head removal, but for future reference: Place the tool lightly on screw head & rotate axially 'til the tool drops into the screw head for a comfortable, firm fit, before applying pressure & torque for screw removal. If the tool does not drop in the screw head for the comfortable, snug fit, you may have the wrong tool or the wrong size. Try a different size 'til U get the right fit before applying pressure & torque to remove the screw. It can save you grief from a ruined screw head.

This doesn't look ANYTHING like my A1278. You should check that not every A1278 is the same.
All Non-Retina 13" MacBook Pros and the Late 2008 Aluminum MacBook have the same A1278 Model Number (I guess due to the almost identical chassis).
