    • Remove five 5.1 mm T10 Torx screws from around the outer perimeter of the fan assembly.

    You don't have to remove the fan assy to get to the wifi board & card. It can be done with the fan assy still attached.

    Fat Mango is correct. That said. If you do pull the fan assembly note that the screws are all held in with blue Permatex and breaking them free takes a fair amount of effort. Getting a good set of Torx screwdrivers is a must.

    • The fan assembly is attached to the rest of the computer by two cables on the IO board side.

    • Tilt the assembly up away from the IO board.

    • Do not try to remove the fan assembly yet, as it is still attached by two cables.

    • While supporting the fan assembly with one hand, loosen the two T7 captive screws in the fan cable bracket.

    • These screws are captive in the Mac Pro. Do not try to remove these screws from your Mac Pro.

    On my Mac Pro (assembled mid-2017) these are T8 screws. In fact, there were no T7 screws anywhere in my machine.

    • Remove the following screws from the top of the fan assembly:

      • One 10.4 mm T10 screw

      • Three 3.7 mm T4 screws

    'T4' screws here VERY tight - iFixit T4 bit spun out on 2, but managed to get them to turn with T5 bit and firm downward pressure....

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.....

vbob - Antwort

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!!!!

Colin Wright - Antwort

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.
