The sound is coming from the fans of a server.
By pulling out one of the fans, all other fans turn up to 100%.
The microphone is located above the air duct exactly in the middle of the case and thus between two fan fronts.
The soundfile starts with the fans on standard speed. After a few seconds the fans turn up to 100%.
I left them there for a few seconds and then quietly plugged the removed fan back in. This fan now also switches to 100% - this is the single, delayed "speed up" that can be heard from second 35.
About 10 seconds later, all fans return to normal speed. Unfortunately, a colleague came in at that time and ended up talking into the recording. Due to lack of time, I was unfortunately unable to repeat the audio that day, but will certainly do another re-recording in the future.
Feel free to use the sound; no attribution required.
Feel free to write me in the comments what you used the sound for.

Thank you for the detailed information on how you recorded the track, the formatting, and just the overall notes. Your attention to detail is more than appreciated. Thank you for sharing this track (as well as the many others). Keep up the great work (please) haha.
Cheers.

I've used the sound in combination with a few others to create a realistic-sounding turbofan engine. Result is here: https://twitter.com/ImSimplyAnna_/status/1385726553309466626
