Introduction
Le ventilateur de cet appareil n’est fixé que par quelques vis, mais il faut reconnaître que lors de son retrait, quelques fils sont enroulés derrière d’autres composants. Veillez à ne pas tirer ou tirer trop fort sur les fils et à les écarter plutôt que derrière les autres composants avant de retirer complètement le ventilateur. Aussi, gardez une trace de vos vis et de l'endroit où elles ont été placées dans l'appareil car il y a une vis qui est différente des autres. Cela permettra un processus inversé beaucoup moins frustrant!

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.
This guide made the power supply replacement quick and easy.
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
Many thanks to Mr. Laverty and the other contributors. I followed this guide to install a new power supply in my darkened 27” Thunderbolt Display to bring it back from the dead. While the instructions were specifically for replacing the fan, I found that after following them to remove the LCD panel, it was easy to replace the power supply as well. For anyone else who may suspect a failed power supply (loud buzzing and then black), I ordered mine directly from China, supposedly a brand new one. It looks identical to the original in every way and does have a 2018 sticker affixed to it. It took a month to arrive but did the trick. I paid $70.50 for it from wwon_one off eBay (https://www.ebay.com/itm/273134311780). Thanks again for the extremely helpful guide!
