using my iFixit bit set, I'd have to say that the tiny screws for Airport card & cover, as well as fan bezel, are actually T5, not T4 - came very close to stripping the heads on two of the Airport card screws with the recommended T4 bit, but firm pressure and a steady hand with T5 bit got them out. Thanks for the guide - many careful steps to get a scrap of scotch tape out of the fan where its gentle ticks-ticka was driving us crazy thinking something far worse was going wrong.....
Ha! I wondered what would happen if some tiny flotsam was dropped in through the top - terrible! Thanks for the tip!
Likewise, I've had a random noise in the fan at startup, and finally took the fan assembly apart to grab it. It was some even tinier screw from somewhere that had lodged in part of the fan housing. All is very, very well now!!!!
Hey Colin, I have same fan startup nois in my MP. Can you help me and tell how to fix in few steps?
Using Macs Fan Control, I noticed the baseline fan speed of my “trashcan” slowly creeping up from 790 RPM (the usual) to 8 or 900 RPM. Using this guide I took the fan assembly off, and vacuumed and dusted everything with a vacuum, soft brush and canned air. It wasn’t necessary to disassemble the fan unit itself. That did the trick - fan speed is back down to 790 RPM after putting it back together.
PS - in Step 5, a Torx T8 screwdriver seemed to fit just fine for the fan cable bracket screws.
