Question Noise from computer

[razu3811]

Hi, I hope everybody is doing well. I have had this noise from my computer every `0 - 20 minutes for 2 days. it happened 1 time 1 month ago and sometimes it stops when I tap on the cooling fan side. Here's the sound I recorded:

I opened my laptop case and the cooling fan seems clean from the outside.
Any idea why this could happen?

Model: Dell latitude e7450

Welcome to the forums, newcomer!

Did you remove the fan from the cooling assembly to see if there's hair follicles or dirt/debris impeding the fans rotation? While disassembled you can inspect the vents for any clogs and clean accordingly.

Just listened to the audio clip, that fans going to give out, might want to keep a replacement fan handy.
