The right fan of my MacBook Pro was humming and rattling like crazy.
The 26 Piece Bit Driver Kit and the Spudger came in very helpful of course. The MacBook was ready for the operation in no time. The fan is fixed with 3 philips screws. One of these was fixed so strongly I damaged the screw in my efforts to unscrew it before it came loose. With the two other screws out, I managed to tilt the fan until the attachment broke. My new fan is fixed with two screws only but it works perfectly and more important, silently!
I got help from an Indian technician who dropped by at the office to fix something else.
