Windows 10: Laptop fan weird noise with video

Hello, while I was using my laptop the fan randomly started making weird noises and vibrating and it has been like that since. Here is a video: https://youtu.be/8EQD-wHJ7UE

Whats causing it to do that?

Laptop occasionaly turns restarts with blue screen and weird fan noise

I have a Lenovo G50 Laptop.
For past few months , sometimes while using it, it restarts with a blue screen and then there's a weird noise from the laptop like a fan getting stuck.

I checked the system logs, the error says memory management issue. So my assumption is something to do with RAM or Harddisk.

I tried the below:

1. I did a windows harddisk scan but it did not show any errors.
   
2. Checked speed fan SMART , but it shows no error.
   
   
   
   
   1. Lenovo also has hardware scan tool, and it scanned all devices but showed no error.
      

I'm thinking of upgrading my harddisk to a new SSD but not sure if the HDD is at fault.
What could be the issue?

 

Fan noise

Are there any problems with the fan noise? IS it loud or can you hear it at all? I currently have the Lenovo Yoga 920 and the fan is so loud!!! I need one with no fan noise or very very very quite noise.

Noise Issue

There is a weird buzzing noise coming from my laptop. I have checked and it is not noise from the fan. I researched it and found out that this noise resembled a noise coming from a hard drive with a stuck motor. It sounds like that, but my laptop has an
ssd not a hdd. Any suggestions to finding out what this noise is and how to possibly fix it would be greatly appreciated.
