Hi,
Here are some troubleshooting steps that may help in identifying the issue.
- First is to open your laptop and make sure there's no dust on the fans and since it's already opened apply new thermal paste on the CPU and GPU that may help.
- If the clicking and vibrating sound is still present, take the HDD off your laptop then boot it up and observe if you'll still hear the weird sounds.
- While the HDD is out and if you don't hear those weird sound that means it's the HDD that is producing the sound.
