Acer Aspire E5-574G Rattling Fan, the fan starting producing rattling sounds& it doesn't spin smooth

Hello, I've been using my Acer Aspire E5-574G laptop (Windows 10) for 3 years and recently the fan starting producing rattling sounds and it doesn't spin smoothly (without "sensed" overheating). The laptop's performance is normal.

I've got the inside of the laptop cleaned and the rattling stopped for about 2 weeks. However, it's just started rattling again.

It's also worth mentioning that I check the Task Manager when the rattling starts, and usually a "System Interrupts" task takes 100% of CPU then it suddenly vanishes. Does this imply that there's something wrong with the hardware (the fan, specifically)?

Also, I've performed a disk check scan using the command prompt and it showed no problems. The drivers are also supposedly updated according to the Windows updater.

If you have a 2.5" Sata-3 mechanical HDD installed check that out too but most likely it is a bad fan bearing that causes the noise, you have to replace the fan (only $13 and an easy job), here is a video how to do that (first disconnect the battery):
