I think my fan makes some noises when my laptop is cold in the morning... Cold means 18°C... Is it dangerous?

After a few minutes or even seconds, the sound stops.

I’m a 21 y/o college student whose laptop fan was being too loud to use in class and I decided to take matters into my own hands so I took the risk of completing these replacement instructions and I’m so glad I did! My laptop fan no longer makes noise and I didn’t have to take it to Apple and have them overcharge me for something simple enough for me to do at home. Thank you!!
