Introduction

The fan in this device is set in by only a few screws, but recognize that when removing it, there are a few wires that are wrapped behind other components. Make sure not to tug or pull too hard on the wires, and rather move them out from behind the other components before completely removing the fan. Also, keep track of your screws and where they were placed in the device as there is one screw that is different from the others. This will allow for a much less frustrating reversed process!

The screws marked in orange don't need to be removed, all they do is hold the magnets on the LCD.

  • For the first of the four wires (furthest away from the wire that is held in by a screw), grab onto the connector and pull slowly.

  • For the next connector, which is right next to the previous wire, there is a piece of tape that is sealing it to the board. Remove this first.

What is this connector for?

I imagine this connector is going to be for display data (i.e. LCD data).

I have been having trouble with fan noise -- a noisy, rapid thumping sound, especially on startup but getting worse over a few weeks and lately persisting all day. Following this excellent guide, I removed the fan and examined it. I could see nothing wrong except perhaps a fine layer of dust on the blades, no worse than could be expected. I did not manage to disassemble the fan itself, as its two-part housing is very firmly clipped together, but applied a vacuum cleaner hose to both the entry and exit sides to clean it up as much as possible. I put it back and reassembled the whole display, and am pleased to report that the noise has completely disappeared. This may be good news to anyone dismayed by the apparent non-availability of replacement fans.

I had the rumbling fan cleaned by a pro. but the rattling didn't go. I just finished replacing the fan on my 27'' Thunderbolt Display using these instructions, and so far so good after 3 hours. It usually started the rattling after 30mn!

I purchased the fan on eBay. There were a couple available then.

I got the fan for $18 and spent 30mn on the job. At the Apple certified spot in town, they were going to charge me $250! I bought this Apple Display second hand for $250! and now it is back to its old self, working like a charm :)

Thank you very much for this web page which walked me through the process.

By the way, for a succion cup I used the two small ones that are attached to my soap holder, from the bathroom tiled wall; worked just fine and I didn't have to spend $20 to buy one.

cheers
